The Risun E series low viscosity triethoxy capped polymer is with excellent molecular adhesion, which can meet the requirements of car assembly and electronics products. The sealants made with Risun E series polymer Release a small amount of ethanol gas when curing. Using more eco-friendly dibutyl tin diketonoate as catalyst and secondary amino silane as curing agent reduces the release amount of methanol. E can also be mixed with, for example, Risun 12000T trimethoxy polymer to make a fast curing system. Only a little of dibutyl tin diketonoate can make curing faster. |
