Chemguard fluorosurfactants improve UV stability, enhance anti-soiling, and improve the weather resistance of caulks. Fluorosurfactants improve bond strength by increasing pore penetration, which increases the total surface area in contact with the caulk. Fluorosurfactants also reduce surface tension, which greatly improves adhesion on lower-energy surfaces and on materials with surface contamination. Adding Chemguard fluorosurfactants can increase open time in certain formulations, creating a wider application window without slowing curing. The addition of fluorosurfactants also can eliminate silicone bleeding.
