LS-770Silicone Plastic Steel Door and Window Sealant

1.single component
2.neutral curing
3.no corrosive characteristics
4.good tension performance
Product description:
single component, neutral curing, no corrosive characteristics, ultraviolet radiation proof, ozone resistance, high/low temperature resistance, good tension performance, good compression performance and good adhesive force, especially good adhesive performance for PVC materials. Mainly used for each kind of plastic steel door and window installation and glass, window frame joint sealing, stone, aluminium plate and concrete joint sealing, and many other purposes.
Construction requirement:
The construction surface must be clean, dry, and cannot be used for structural assembly. And cannot be used for the surface that is easy to penetrate oil, plasticizer and easy to frost and moist, and for the insulating place, and for the circumstance which is easy to leak water continuously.
