A .125″ thickness of acrylic is 2 to 3 times more impact resistant than double strength window glass, 4 to 5 times more impact resistant than wire glass or other glasses. A .250″ thickness of acrylic is 9 to 10 times more impact resistant than wire or other glasses.
Acrylic Sheet is harder and more rigid than Polycarbonate and therefore it is less likely to scratch than the softer more flexible Polycarbonate.
By nature Acrylic resin has a high level of UV resistance. In fact when blended with other plastic materials in the manufacturing process, the amount of acrylic resin added to the blend determines the UV resistance of the end product. Polycarbonate on the other hand tends to optically degrade with exposure to UV light and gradually takes on a slightly purple cast.
Most Acrylic Sheet manufacturers guarantee that their sheets will show no visible yellowing for 30 years. They also guarantee that their sheets will retain a high level of light transmission for 30 years. On the other hand Polycarbonate manufacturers offer only a 10 year guarantee.
A 10″ carbide tipped circular saw with 80 teeth.
Yes they are designed to bore rather than cut and they are available at Industrial Plastics & Paint stores
Over the years there have been many products that claim to glue ALL PLASTICS, up to the writing of this FAQ we have not found one that works well. It is however possible to achieve reasonable adhesion if you have a large surface area and do not need to rely on peel strength. 3M Spray 90 works well in this situation but nothing we have found will glue two edges together with any measure of success. Polyethylene, Polypropylene, UHMW all fall into this NON GLUE-ABLE category.
The best answer to this question is "that depends on the intended use". Methylene Chloride is a good solvent cement for an interior application, but it is not good in wet or exterior applications. Weld On 16 is a thickened cement that is an improvement over MC, however it is very difficult to achieve the invisible joint that you get with MC, so no good for Display work. The very best adhesion is achieved with a 2 part thickened cement but once again requires a deft hand to product a clean joint.
NuFlex® 333 Aquarium Silicone Sealant is a one-part, moisture curing, 100% silicone sealant that has been specially formulated for the construction of aquariums. It will never shrink, dry out or crack; remains permanently flexible and is harmless to fish and plants.
A sticky or greasy film which forms on the top of some amine or poly-amide-cured epoxy resins. It is removable by scrubbing with soap and water.
Yes. However the white solid or haziness is a mass of resin crystals and crystallized resin will not cure properly. Therefore you will need to melt them by heating the container to 120°F. The resin will clear up and be as good as new.
Probably. Hardeners yellow and darken over time due to contact with air and sunlight. This does not affect their performance. To satisfy yourself do a small test and make sure it cures properly.
All solvent-free epoxies have essentially unlimited shelf lives so long as they are stored in sealed containers. The resin may crystallize or the hardener may darken but this does not affect its performance. If the material is more than a year old do a test to satisfy yourself that it cures properly.
In general, polyester resins won't cure properly or bond well to epoxy resin products without a "tie-coat" barrier resin in between. System Three SB-112 resin system can be used as a tie coat in between epoxy laminating or coating resins, and polyester laminating or gelcoat resins. Using this resin allows you to gelcoat an epoxy-built or epoxy-repaired boat.
The preferred method is with System Three paste pigments. You can add these up to 10% by weight of the PYesart A resin. You can also use universal paint colorants from the paint or hardware store, but only up to 2% by weight of the resin.
The only way to speed the cure of our epoxy resin products, once they've been applied, is to heat the room or the area that your project is in. Every 18°F increase in temperature cuts the time it takes for the resin to cure in half.
No. As long as the epoxy is completely cured, the physical properties will not be affected.
Cured epoxy systems are very chemical resistant, and need to be removed with an epoxy-type paint stripper containing methylene chloride, or by a combination of heat for softening followed by scraping. Uncured epoxy resins and hardeners can be cleaned up with ketones, alcohols, or lacquer thinner. White vinegar will clean up unmixed resin components.
No. Any wood that's been coated with epoxy will be sealed, and when it's cured it won't accept stain. Stain wood first; then apply epoxy resin.
Dye stains are preferable because they leave no surface film. But in general, any stain can be used so long as it is completely cured before applying mixed epoxy resin. However, it is prudent to do a test by staining some scrap and then applying epoxy. Check for appearance and bonding.
Yes we carry a product called Por15 Tank Sealer that is impervious to gasolene>
Yes we sell Cold Cure Epoxy Resin that will cure 35ºF / 0ºC in 100% Humidity. It will even cure underwater!
Polyester Resin will not adhere well to Epoxy resin, howver you can apply Epoxy over Polyester Resin
Epoxy adhesives, being gap-filling glues, need only enough clamping to close the joint. Unlike other glues epoxy does not require high pressure to make a proper glue joint. In fact too much pressure will cause the epoxy to be squished out of the joint resulting in a starved joint and poor adhesion.
I made a large batch and found a few areas that are still sticky after most of the surface is cured hard. What happened?
The material was probably not thoroughly mixed and unmixed material was scraped from the container onto the surface. When mixing always be sure to mix from the bottom to the top and scrape the sides of the container and the stick. Experienced users dump and scrape the mixed material from the first container into a second and then mix again. This totally avoids the problem described above.
I made a large batch and found a few areas that are still sticky after most of the surface is cured hard. Can I fix it?
Yes. First, scrape off what you can. Then pour or wipe a suitable solvent on the surface. Wear a respirator or provide proper ventilation when working with solvents. Wipe or scrub the resin surface. This will remove residual uncured resin but won't harm any cured resin. Sand the underlying cured resin and apply a fresh coat properly measured and thoroughly mixed. Note: Over bare wood the fresh coat of resin will need to be worked into the wood with a stiff-bristle brush to mix any residual uncured material into the fresh material. This will ensure that the fresh coat will adhere properly to the wood.
Uncured epoxy is removed as you would spilled resin. Scrape as much material as you can from the surface using a stiff metal or plastic scraper-warm the epoxy to lower its viscosity. Clean the residue with lacquer thinner, acetone, or alcohol. Follow safety warnings on solvents, and provide adequate ventilation.
FRP panels may be used in this application; however we do not manufacture FRP doors.
FRP can be installed directly over ceramic tile, however non-porous surfaces require the use of rivets unless the surface of the tile is opened by sanding or use of a chemical abrasive. Adhesive should be used on porous surfaces only. We recommend using Advanced Polymer Adhesive.
FRP can be installed with metal fasteners. Pre-drill holes (use 3/8" drill bit) in the Glasbord panel on 16" centers. Using pre-drilled holes in FRP as a pilot hole, drill, fastener holes in metal with a bit no larger than 9/32". Seal all joints with a silicone sealant.
Painting FRP is not recommended because the finish is designed to be a non-adherable surface. If painting is necessary, an epoxy or acrylic-based paint is suggested.
FRP can be used as a tub surround, although there will be seams as the product is only available in 48" widths. Install the seam to the far end of the tub away from water spray. Silicone caulk well and leave expansion room at the joints.
FRP is commonly specified for food preparation, pharmaceutical, and medical settings where sanitary highly cleanable walls are required
FRP is ideal for this setting. FRP is known for its moisture and corrosion resistance in high humidity installation. It won’t rust, pit, dent or peel like a metal grid system.
No, FRP does not support mold or mildew per ASTM D3273 and D3274.
No, embossed panels have been tested to be as cleanable as smooth panels and maintain an acceptable appearance longer than smooth panels. Crane Composites suggests embossed panels over smooth for years of cleanability.
Panels are packaged 50 on a skid and the 0.09" thick panels weigh .65lb per SF. The skids weigh approximately 1000lbs each
Waterbased FRP Adhesive offers professional-strength and is specifically formulated for the installation of FRP (fiber-reinforced plastic) panels over most porous surfaces. It is ideal for bonding FRP panels to drywall, non-treated plywood, greenboard, concrete, concrete backerboard and most other common porous building materials. It offers quick grab and strength development that requires minimal bracing. Waterborne FRP Adhesive provides permanent flexibility, allowing materials to expand and contract with temperature changes without compromise. In addition, it is easy to trowel and cleans up with water. A safer alternative to solvent-based technologies, this VOC-compliant, nonflammable formula emits no harmful or offensive odors into the environment, promoting healthier living and working conditions.
Solvent based adhesive must be used if the application is on top of a sealled surface or exterior application.
The catalyst for Promoted Polyester Resin is Methyl Ethyl Ketone Peroxide (MEKP)
All polyester resins must be mixed with M.E.K.P. (Methy Ethyl Ketone Peroxide) catalyst (unless otherwise specified) to induce the cure. The Proportion of catalyst required is dependent on the ambient temperature ( ½ to 2% by volume).
Polyester Resins are "air inhibited", which means they cannot fully cure if exposed to air. This is desirable if you are building up layers of resin & fabric as the resin will stay tacky between layers. This tackiness provides a good bond between coats.
To counter the tackiness you are required to add "Air Dry Wax" to the final coat. This wax floats to the surface of the application while the resin is still liquid and then forms a barrier to the air, allowing the resin to full cure to a non-tacky finish.
So Unwaxed Resin if used in the final layup requires the addition of Air Dry Wax at a rat of 2 oz per gallon of Polyester Resin.
While Waxed Resin already has the Air Dry Wax added. Not that you can use Waxed Resin for all layers if you are doing only a couple of layers and the layup is completed within 24 hours of the first application. This is because the wax remains soft and will re-liquefy and permeate through the top layer along with the wax in the wet layer. If you don't complete your lay up within the 24 hour period you will need to sand between coats and wipe with alcohol.
PRO-FIL: Cabosil is a light weight, low density fumed silica powder additive for use in all types of resins and gelcoats, although when used to thicken polyester or vinyl ester, creates an excellent medium sanding, non-slumping compound.
GLASS BUBBLES: Glass Bubbles is a hollow silicone dioxide powder. It is a non-absorbent additive used to extend all types of resins and gelcoats. It can be used in resins alone however, its main use is to be used in conjunction with other fillers to create easy to sand compounds.
INTERFIBE: Interfibe is a treated cellulose fiber and its the replacement filler for asbestos. It is an economical additive for all types of resins and gelcoats to create a very strong hard to sand, gap filling, bedding and/or filleting compound.
ECONO_FIL: Industrial Talc is a magnesium hydroxide powder and is the most economical filler. It is an additive used to thicken all types of resins and gelcoats and is easily applied and sanded.
MINI FIBRES: Mini Fibers are dense, ground polyethylene fibers. It is an additive for all types of resins and gel coats although, when mixed with epoxy resins, creates an excellent medium sanding, non-slumping compound.
CHOPPED STRAND: Chopped strand is actual strands of fiberglass chopped into 1/4" lengths. It can be added to any type of resin or gelcoat alone or in combination with other fillers where strength is required.
MILLED FIBERS: Milled Fibers are ground fiberglass fibers. They will add moderate strength to any type of resin or gelcoat alone, or in combination with other fillers.
NON-SLIP ADDITIVE: Non-slip Additive is a medium grade sandblasting sand (crushed walnut shells) that can be added to any type of resin, gelcoat or paint to make any area a slip-proof surface.
Mix the filler(s) in small quantities at a time until the desired constancy is achieved. It is the same process with either Epoxy or Polyester type resins. However, with Epoxy Resin mix the resin and hardener before you add the filler. The opposite is true with polyester resin, you catalyze after mixing the fillers into the resin.
Gelcoat is formulated using Polyester Resin, Fillers and Colour Pigment. Therefore you can use the same catalyst chart as Polyester Resin.
isophthalic ( iso ) resins are higher grade resins than ortho resins in that the molecular structure is denser. It is a special raw material utilized in corrosion resistant and/or premium grade polyester resins. Theses resins will exhibit a higher heat distortion temperature, higher strength, greater flexibility and are more waterproof than Orthophthalic resins.
Cloth is a wovern fabric with strands of fibreglas woven in vertical and horizontal directions at 90 degree to each other. It offers strength in bilateral directions with the stands. Cloth is often used in conjunction with other materials like Mat to augment the strength in multilateral directions.It is ideal for small projects like waterpoofing, covering a canoe and lightweight moldings & repairs. It dries transperant and can be used with epoxy or polyester resins
Mat is the most popular forms of reinforcement for many non-structural applications. It is easy to use and easy on the pocket book. You can quickly add thickness into molds, repairs and even parts. The Glass Strands randomly form the material that will effectively hide print-through of heavier fabrics and augment the strength and stiffness of parts when combined with other reinforcements.
NOTE: Mat is NOT COMPATIBLE with EPOXY RESINS due to the binding starch that keeps the glass strand together.
Custom coloring gelcoat is an art rather than a science. Achieving color matches in small batches is not something that can be formulated. So you will have to proceed slowly adding a little at a time until you achieve your desired color. However, colour paste should not be added in excess of at a ratio of 6-8% by weight or 60 ml paste to 1 litre of gelcoat. This color mixing will need to done BEFORE you add catalyst to the gelcoat.
