I am using MIL-DTL-64159B Type II 2K Waterborne Polyurethane CARC. Also what would you recommend for a desiccant dryer for a 165 psi 33 gallon compressor
Any decent 3 stage unit should help, however with a 33 gallon tank you also might consider an aftercooler. It’s also important when storing the catalyst to spray argon or nitrogen into the container before resealing which will prevent atmospheric moisture contamination & CO2 gas. Another consideration is to allow the material to rest 10 minutes or longer after catalyzing which will allow the initial blast of CO2 to escape from the mix.
