Don't risk
Don't mix too much (4 oz resin + 4.oz hardener 1+1 ratio) according to the owner, that will cause it to generate too much heat and cure extremely fast. Don't use a vacuum chamber to remove bubbles, that causes heat generation and rapidly decreases curing time. Don't follow the instruction and stir for 3 - 5 minutes, according to the owner thats way too much., only stir for 1 minute, otherwise drastically reducing curing time. By drastically I mean curing to the point of being unworkable in 15 - 20 minutes. This is the ***** epoxy resin I. have ever used. Called customer service the initial gentleman we spoke with said they would replace the product, but wanted to speak with the owner who. is also the "chemist" we said fine. The "chemist/owner " returned the call and proceeded to tell us everything we had done wrong, mixing for more than one minute, even though everywhere on their website and even in the product description it says to mix 3 - 5 minutes. Plus the other things mentioned previously. Owner / Chemist, Refused to replace product with same or other product, never apologized for having trouble with their inferior product. Too many other places selling epoxy resin to risk using these people. I'm sure. this critique will never make it to their website. Attached is a video of epoxy after 15 minutes, it's pretty, but you can't do much with it.

Hello,
I am sorry this epoxy did not work for tour application. As I said on the phone, we can not replace a FREE sample given to you over 8 months ago. Further, as we discussed the tumbler epoxy is only designed for thin coatings only. The picture you provided clearly shows a casting. I tried to help and problem solve - by giving you advice: To avoid heat: mix less than 3 minutes, avoid pressure pot, do not let mixed product sit for extended amounts of time. I spent 10 minutes on the phone with you. Very saddened to see this review but will try harder next time.
