178 One-component neutral room temperature curing silicone weatherproof sealant
Features &Benefits
1. One-component, neutral room temperature curing silicone weather-resistant sealant.
2. Easy to use, with good extrudability and thixotropy in the temperature range of 4~40℃.
3. It has good adhesion to most building materials and surfaces.
4. Excellent weather resistance, anti-aging, UV resistance, ozone resistance and high and low temperature resistance, making it an ideal weather-resistant sealing material.
