Proflex does claim to be silicon free but it acts just like a silicone caulk for better or worse.
The only commonality with a silicone caulk is that it comes in a 10 oz tube and seals against water when cured. It's properties are much different, Technical data sheet
Sure but it applied and acted like silicone sealant. Perhaps it sounded like I was casting doubt on the claim that it did not contain silicone. I was not.
Your first post and the use of the words "claim" and "for better or worse" might lead some to believe that the product was similar to silicone caulk. It is not. I've found that the viscosity of uncured Geocel Tripolymer sealants is much greater than silicone and it's application is dissimilar. It also has greater bond strength, more elongation, greater durability in weather, and can be painted.
The Dicor non-sagging Lap Sealant has somewhat similar properties but it is a Silaprene product, probably using EPDM as the polymer and contains quite a bit of Naptha. Dicor is pretty mute about the product's technical specifications but it seems to work well for a lot of users on this Forum.
