Why choose butyl rubber sealant not the asphalt sealant tape ?
Butyl Rubber Used as a waterproofing and moisture/vapour waterproof sealing system in the building and construction industries has many features other than asphalt:
Butyl Rubber is self-healing (if punctured will fuse back to re-create seal as sharp object removed)
No volatile organic content in Butyl Rubber products or used in its manufacture (environmentally safe,Green )
Butyl Rubber has some degree of resistance to organic solvents
Butyl Rubber has a long shelf life
Butyl Rubber Rubber is permanently visco-elastic (highly conformable, withstands expansion and contraction)
Butyl Rubber's visco-elasticity is retained at low temperatures - soft and conformable to -30Deg C
Butyl Rubber's visco-elasticity is retained at high temperatures - does not flow at 110Deg C
Butyl Rubber is available in flame retardant versions, asphalt is not
Butyl Rubber and asphalt are both available in formats tested for water potability
Butyl Rubber is available in thin gauages down to 0.5mm
Butyl Rubber is compatible with all common acrylic, polyurethane and neutral cure silicone sealants
Butyl Rubber is available in versions compatible with oil/solvent based paints
Butyl Rubber is compatible with water/acrylic based paints
Butyl Rubber is resistant to mildew
Butyl Rubber's application temperature is a wider range: 5 Deg C to 40 Deg C Asphalt 's application temperature is 15 Deg C to 30 Deg C
Butyl Rubber's operating temperature is Minus 30Deg C - 80 Deg C
Asphalt's operating temperature is Minus 10Deg C - 55Deg C Max.
Butyl Rubber is UV Resistant - it does not harden with time
Butyl Rubber is pressure sensitive - no external heat required for application in all situations
Butyl Rubber has excellent sound and vibration absorption over entire product's life
Butyl Rubber will not stain surfaces or leach oils (no messy clean-up)
Butyl Rubber bonds to all non-porous standard building materials (including HEVAC building wraps), asphalt does not
