Antas-SK59 Silicone Weatherproof Sealant for None-staining
Model: antas-SK59
Antas-SK59 is a one-component, neutral-curing, high-movement-capability silicone
weatherproof sealant, specially designed for high-rise curtain walls and large-panel
curtain walls. It exhibits excellent weather resistance and anti-staining properties, with
no risk of staining porous materials such as natural stone. It effectively minimizes
vertical run-down staining near horizontal curtain wall joints.
Features
- Non-staining to various porous building materials such as marble, granite, limestone, bricks, mortar, and ceramic tiles.
- Easy tooling with good extrudability and thixotropy within the temperature range of 5℃ to 45℃.
- ±50% movement capacity
- Excellent weather and aging resistance, virtually unaffected by ultraviolet rays, ozone, and water.
- The cured silicone rubber has good resistance to high and low temperatures. It maintains good adhesion and elasticity within the temperature range: -50℃ to 150℃.
- Compatible with other neutral silicone sealants.
