High Performance Neutral Silicone Sealant OLV4800 On Roof & Gutter
Technical Data
Description:
High Performance Weatherproofing Silicone Sealant OLV4800 is a one-component neutral curing silicone sealant with excellent adhesion, weatherability and elasticity for weather sealing in curtain wall and building facades, especially suits applications in the areas with large difference in temperature and low humidity.
Main purposes:
1. For weatherproofing sealing nonstructural curtain wall joints, facade joints and system;
2. Weather sealing in metal (not including copper), glass, stone, aluminium panel, and plastic;
3. Excellent adhesion to most common building material.
Characteristics:
1. One-component, neutral-cured with excellent adhesion, weatherability and elasticity for weather sealing in curtainwall and building facades;
2. Excellent weatherability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes;
3. With good adhesion and compatibility with most building material;
4. Remain flexible over a temperature range of -400C to 1500C.
