TNS721 One Component Silicone Sealant for Curtain Wall Glass - 25HM/35HM/50HM

TNS-721 is a one-component, neutral-cure silicone sealant designed for demanding weatherproofing applications. It cures at room temperature to form a high-modulus, high-strength elastic seal with outstanding adhesion to most common construction materials without the need for a primer. Demonstrating excellent resistance to weathering, UV radiation, ozone, and extreme temperatures, it maintains long-term flexibility and performance without corroding substrates. Its compatibility with other neutral silicone sealants ensures versatile application, making it an ideal choice for dynamic joints and seams requiring superior movement resistance and environmental durability.
