NF 202 Weatherseal Neutral Silicone

NF 202 Weatherseal Neutral Silicone

 

Product Description

 

NF 202 Weatherseal Neutral Silicone is a premium performance, neutral cure silicone sealant exclusively designed for weather sealing and glazing applications. It forms a highly resistant weatherproof seal on windows and building facades. This 100% silicone sealant offers permanent elasticity, remaining unaffected by sunlight, rain, or snow for many years. It exhibits exceptional resistance to temperature extremes, is very low odor, and non-corrosive. With excellent flexibility and adhesion to numerous porous and non-porous substrates, it is ideal for large-scale construction and glazing applications. NF 202 cures fast, has a low modulus, high elasticity, and a high viscosity non-slump formula.
