Description
FS704 is a non-sagging fire resistant sealant with excellent processing properties. Based on hybrid polymers, FS704 is a paintable elastic sealant free of phthalates, isocyanates and silicone. In a reaction with humidity from the air, it forms a soft elastic sealant that shows good resistance to light, ageing and weathering.
Features and benefits:
- Up to 2 hours fire resistance – tested to EN 1366-4.
- Phthalate free, isocyanate free, silicone free.
- Up to 25% demonstratable movement in cold state – tested to ISO 11600.
- Creates a smoke seal.
- Acoustically capable up to 66 dB.
- Air Pressure tested up to 600 Pa.
- Can be painted if required.
