FS-E
FS-E(Caulk Sealant) is a one-component, neutral silicone fireproof sealant with good flexibility and adhesion. When exposed to fire, it forms a dense mesh structure that can effectively prevent the spread of flame and heat.It is widely used for sealing holes and surfaces such as floor slab gaps with small displacement, wall joints, mechanical pipes, ventilation pipes, and thermal insulation pipes.
Simple working condition
Product advantages:
Non-toxic smoke;
No halogen, sulfur or other toxic substances;
Over 60 years lifetime;
Water-tight, Smoke-tight;
Radiation resistance; Resistant to Design Basis Accident( DBA );
