Window & Door Neutral Silicone Sealant FNS80

One-component, neutral curing silicone sealant for windows and doors, interior and exterior wall caulking seal, sandwich panel and wood walls for sealing. It is widely used and has good adhesion to most of building materials.

Features & Benefits

Easy to use, with good extrudability and thixotropy in the temperature range of 5 ℃ to 45℃.
Neutral cure, no pollution and corrosion on metal, wood, coated glass, concrete and other building materials.
Excellent resistance to weather, UV, ozone and water.
Excellent resistance to high and low temperature, maintain good flexibility at a range of -50℃～150℃ after curing.
Good compatibility with other neutral silicone sealants.

Applications

Installing window and door, glass glazing, sandwich panel and wood wall
Filling and sealing the gap for outdoor and indoor wall
Other general purposes

Standard Compliant
