TWO-Component Polysulfide Sealant For Insulating Glass
Two-component room cured polysulfide sealant, specifically designed for the manufacturing of insulating glass units used for window and door as well as for edge frame curtain wall system.
DESCRIPTION/APPLICATIONS
Two-component room cured polysulfide sealant, specifically designed for the manufacturing of insulating glass units used for window and door as well as for edge frame curtain wall system. The sealant is sensitive to temperature and humidity while mixing. The higher temperature,the faster curing speed
TYPICAL PERFORMANCE
• Excellent adhesion to a wide range substrates including glass,aluminium alloy,and galvanized steel,stainless steel.· Excellent temperature stability:-60℃ to 180℃.
• High elasticity and strength
• Solvent free,primers are not required.
