Saveto Vetoflex PU780 – High-Performance Polyurethane Sealant
Saveto Vetoflex PU780 is a one-component, moisture-curing, polyurethane-based sealant designed for high-performance sealing applications. Its low modulus and elastomeric properties make it ideal for movement and static joint sealing in both indoor and outdoor environments.
This weather-resistant, paintable sealant offers excellent adhesion to various construction materials such as concrete, steel, and wood without requiring a primer. Its durable and flexible formulation accommodates joint movements, making it suitable for sealing pre-cast panel joints, expansion joints, and materials with differing thermal expansion rates.
