Advanced Structural Silicone Sealant FNS31

Single component, neutral and room temperature curing, with good adhesion, usually no coating required.

After curing, have good adhesion to most building materials, such as glass, aluminum, steel and stone surface.
After curing, the product forms a cold-resistant, heat-resistant, non-corrosive elastomer with excellent weather resistance, aging resistance, UV resistance, ozone resistance.
It has good compatibility with other silicone sealant
Mould proof and fungi proof.
