Q: Are The Products Waterproof Or Watertight?
A: Cured PC-Products are fully waterproof and watertight. PC-11® and
PC-Marine™ can be used for both wet and dry applications.
Q: Is There Anything Harmful Or Toxic in PC-Products?
A: Uncured epoxy should not be eaten (common
sense). The hardeners are typically corrosive in contact with eyes-AVOID ACCIDENTAL CONTACT. Some people can become sensitive to epoxy resin and amine hardeners. Proper hygiene should be practiced. Wash skin shortly
after contact with epoxies. Cured epoxy is totally safe. MSDS sheets are available through this web site or upon request.
Q: What Will PC-Products Bond To?
A: PC-Epoxy
adhesives bond to many different surfaces such as metal, wood, ceramic, masonry and hard plastics. Soft waxy type plastics are difficult to bond such as polyethylene and polypropylenes. Spot test adhesion if in doubt.
Q: How Should I Prepare The Area?
A: To achieve maximum adhesion remove oil. Dirt, rust, paint and water. Use a degreasing solvent (alcohol or acetone) to remove oil and
grease. Sand or wipe away paint, dirt or rust. Roughing up the surface increases surface area for a better bond.
Q: What Is The Cure Time Of The Products?
A: Cure time
varies with each product and the surrounding temperature. Cold will retard the cure time as heat will accelerate the cure time.
Cure Times:
PC-7® cures in about 24 hours @ 70ºF
PC-SuperEpoxy® cures in 3-4 hours @ 70ºF
Putty Epoxies™ cure in 1 hour @ 70ºF
PC-11® cures in 12 hours @ 70ºF
Q: Where Can I Purchase PC-Products?, Are Products Available Direct?
A: PC-Products can be purchased through your local hardware store. Larger quantities may be ordered at these stores also. If your retailer cannot or will not help you we can ship direct.
Q: Does SuperEpoxy™ stick to plastic?
A: PC-SuperEpoxy™ bonds to many surfaces including hard plastics. Plastic is a broad term and includes many types of polymers. It is always
best to spot test if in doubt.
Q: How Fast Does SuperEpoxy™ Really Cure?
A: It cures fast enough that there is significant strength after 3 hours. At 70ºF the working
time is 15 minutes. It is still possible to reposition work up to 45 minutes.
Q: When Should ROT TERMINATOR® Be Used Instead Of PC-Petrifier?
A: PC-Petrifier® has found its
way into a variety of applications where there is no other substitute. However, in severe cases of rot, PC-Rot Terminator® is the preferred hardener. Rot Terminator® provides greater structural strength than
PC-Petrifier® and it is a two-part epoxy rather than a one-part emulsion. Rot Terminator® would be your best bet in a marine environment and where structural integrity is needed.
Q:
Does PC-Woody® Accept Stain And Paint?
A: After PC-Woody® has cured the surface must be sanded prior to staining or painting. Some types of wood and stain can be difficult to match. PC-Woody® is
neutral in color and lacks many of the natural colors such as found in oak. In order to match the surrounding wood more than one color of stain may be required. When painting it is preferable to prime using an oil-based
primer or a stain sealer.
Q: How Easy Is It To Sand PC-Woody®?
A: Of all the PC-Products, PC-Woody® is the easiest to sand. PC-Woody® must be cured for at least 12 hours
prior to sanding otherwise sandpaper will gum up.
Q: How Dry Must The Wood Be Before Applying PC-Petrifier®?
A: Wet wood has a limited capacity to accept PC-Petrifier®. The
drier the wood the more PC-Petrifier® can be soaked into the wood. Eliminate the source of water and ventilate using fans. Lamps will accelerate the drying.
Q:
How Much Material Do I Need To Purchase?
A: One gallon of epoxy will cover: 12.8 square feet at 1/8-inch thickness, 6.4 square feet at ¼ inch thickness.
Q:
PC-7® Is Not Curing Fast Enough, Did I Do Something Wrong?
A: PC-7® is a slow curing system and cures slower at lower temperatures. In cool areas a lamp helps to speed the cure.
Q: What Is The Maximum Temperature That The Epoxy Can Take?
A: Although epoxies generally are able to withstand high temperatures for short periods we do not recommend using above 200ºF.
Q: Is There An Easier Way To Mix And Apply?
A: The best method for mixing paste epoxies is to use a stiff knife and a flat piece of wood. The putties are mixed between the
fingers. It is helpful to store the epoxy in a warm area prior to use. Art supply stores offer a variety of palette knives for applying paste.
Q: Can PC-11® Be Used On A Water Tank?
A: PC-11® may not stick to all plastics, test to be sure. PC-11® has not been certified for contact with potable water, but is non-toxic after cure.
Q:
Can PC-11® Be Used In A Refrigerated Room?
A: Epoxies cure very slowly at lower temperatures. It may be necessary to use heat lamps to help the PC-11® cure faster.
Q:
Do The PC-Putty™ Epoxies Stick To Plastic?
A: Some plastics are very difficult to stick to. Some adhesion can be expected to PVC, polyurethane, acrylic, polycarbonate, and fiberglass. The
putties will not bond to polypropylene, polyethylene, polystyrene, nylon and teflon.
Q: Can I Anchor A Bolt Using Any Of The PC-Putty™?
A: PC-METAL™ and
PC-CRETE™ are excellent to anchor in concrete. PC-LUMBER™ is excellent for anchoring into wood. PC-MARINE™ is great for anchoring at the pool or on a boat. For heavy duty anchoring try PC-7®.
