# Best epoxy resin for tumblers: fast cure, clear and heat tolerant Source: https://resinandmold.com/best/best-epoxy-resin-for-tumblers Publisher: Resin and Mold. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://resinandmold.com/how-we-pick A glitter tumbler spins on a cup turner while the epoxy levels, so the resin has to be thick enough to stay on the cup, workable long enough to spread, and set before the turner has run all night. That is why people search for fast cure epoxy resin for tumblers: a coating resin that is dry to the touch in hours instead of a day. This guide compares six two-part coating epoxies by what their Amazon listings state: mix ratio, working time, cure time, any heat figure and the total volume of the kit. Nobody coated cups for this guide. Heat and food contact need care. Most listings here give no heat number at all, and maker data sheets for clear epoxy put the limit at about 108 to 130 F, so check the data sheet before trusting a heat claim. Where a listing makes a food contact statement it is reported as the maker's statement, nothing more. Every clear epoxy yellows in time, whatever the label says. ## Picks ### 1. Bond Craftor Tumbler Epoxy Resin 32oz, Tumble Cup and Coating Mix ratio: 1:1 by volume; Working time: 30 minutes; Cure time: 10 hours; Heat limit stated: not stated A 32 oz two-part epoxy sold for tumbler cups and coating. The listing states a 1:1 mix by volume, 30 minutes of working time and a cure in 10 hours. What the listing offers: - The listing gives every timing a tumbler maker needs: 1:1 by volume, 30 minutes working time, cure in 10 hours. - Sold as a coating epoxy: the listing calls it more suitable for coating objects than ordinary epoxy. - Described as self leveling with no fish eyes, which matters on a turning cup. Limits to know: - The listing claims high temperature resistance but gives no figure, so the heat limit is unknown. - The bullets are short: no yellowing statement, no food contact statement and no list of what is in the box. ### 2. Alumilite Amazing Quick Coat Epoxy 16 Oz, Fast Curing, Crystal Clear Mix ratio: 1:1 by volume; Working time: not stated; Cure time: as little as 4 hours; Heat limit stated: not stated A 16 oz fast curing coating epoxy from Alumilite that names tumblers among its uses.
