Well UScomposites doesn’t say the thin 635 resin can be used in infusion, it can. The slowest hardening version is clear and has a 600cps rating. Only down sides is it takes ages to cure, and is as flexible once cured as a rubber band. Their medium can also be infused. Fibreglast’s epoxy can also be infused and although it has a light amber color, nobody is going to notice it in the finished part. If you want a good infusion epoxy that’s clear and has a good TG look into Huntsman Araldite epoxy. Freemansupply.com or NFGsales.com can help you. But be prepaired they only sell in 5 gallons or more. Their are alot more choices out their just gotta do the research. Most people wont tell what good clear epoxy they are using because it took them so long to find it.
got it
