Q: What’s the best way to mix this?
A: You’ll want to make sure that you have 1 part base resin and 1 part curing agent measured precisely, by volume. Pour each into your mixing bucket, and we recommend mixing by hand for at least 3 minutes and between 3-5 minutes or until it is fully mixed. Be careful to scrape the sides while mixing, but when pouring, do not scrape the sides. This can impart unmixed material that may cling to the side and has not been incorporated. Don’t worry about any bubbles in the mixture, they will all work themselves out.
Q: How long does it take to cure, and what temperatures can I pour this in?
A: Our optimum environment temperature range is 72° - 84°F in a clean, temperature controlled environment. In that temperature range, it will begin to gel in 20-30 minutes, and cure rock hard within 24 hours. Temperatures under 70° will slow the curing process even more, and the closer you get to 60° the curing process will stop. Above 85°, it will begin to accelerate curing,leading to cracking, shrinking and other negative results.
Q: Is your epoxy FDA Compliant?
A: The short answer is, yes. Once our epoxy has cured, it becomes safe, per FDA code, 21CFR175.300 which states "Resinous and polymeric coatings may be safely used as the food-contact surface of articles intended for use in producing, manufacturing,packing, processing, preparing, treating, packaging, transporting, or holding food" and can be used as a "functional barrier between the food and the substrate".
Q: When can I demould?
A: Our optimum environment temperature range is 72° - 84°F in a clean temperature controlled environment. In that temperature range, you can demould between 18 and 24 hours, and its optimal workability will be at 24-30 hours. At 30 hours it will sand and plane as easy as wood!
Q: Can I pour Superclear Table Top Epoxy over a stain?
A: Absolutely, but there are some things to consider. First, you want to let the stain completely dry. give it a couple of days to penetrate and dry. Once it is dry, lightly sand the surface, then clean off any dirt and excess stain left on the surface with 99% isopropyl alcohol. Make sure the surface is extremely clean. If any undried stain is left, no matter how little, the epoxy will either not cure and/or adhere to your wood.
Q: Can I use this on furniture meant for the outdoors?
A: While our epoxy yellow less over a longer period of time vs all other epoxies, in direct outdoor sunlight, any epoxy will yellow much faster. It is left to the discretion of the user, but it should be fine in highly shaded areas that are kept from direct sunlight.
Q: How much mica or pigment can I use?
A: We suggest only using epoxy resin color pigments (like our Supercolor Liquid Pigments), mica pigment powder, alcohol inks and dyes. With that said, 12% is the limit of color that can be added before the curing process is affected. Remember, the higher percent of color you add, the less chance of a perfect cure. If you go too high, your project will not cure. Our limit for ALD-2209 is 12%, which is more than enough to create an opaque finish, but also allows for a smaller percent to achieve a translucent finish.
