MarkVA Posted May 28, 2023 Posted May 28, 2023 Anyone else have this issue with Pro Paste: The resin has become dried out, crystallized, lumpy...less so in the middle. The hardner is just fine, no issues. 1 Quote
Super User MickD Posted May 28, 2023 Super User Posted May 28, 2023 No, must be old. Try nuking it for a few seconds in the microwave. That works for liquid epoxy. Do it in stages, so not to overcook it. 3 Quote
Super User S Hovanec Posted May 29, 2023 Super User Posted May 29, 2023 My rod bond does that on occasion. Like Mick said, a couple 5 second blasts in the microwave will fix it like new. 4 Quote
Chris Catignani Posted July 19, 2023 Posted July 19, 2023 Crystallization of epoxy resin is not any indication of being bad or old. Solid form is its natural state. Usually, its fluctuating temperatures thats a catalyst for crystallization. Simple heat treatment mentioned above will remedy crystallization. A more controlled temperature of about 50°C will make sure you dont over cook it or damage any additional properties it may have (especially the paste resin). Quote
Alex from GA Posted August 5, 2023 Posted August 5, 2023 A safer way is boil a cup of water and put the container in the cup. Quote
