Polysulfide sealant
Characteristics:
● Two component, room temperature cured polysulfide sealant, formulated for secondary sealing of insulating glass units.
● Excellent adhesion to most building materials such as glass, aluminum alloy, and galvanized-steel, stainless steel etc.
● Solvent free, primers are not required.
● High strength and elasticity.

SURFACE PREPARATION:
The glass and spacer achieve good adhesion, and the surface must be clean, dry and free of any residue.
Mix instruction:
When using an automatic pump mixer ensure the mixing ratio is correct.
The mixing ratio by weight is 100:6~100:12. Curing speed can be adjusted (the more Com B, the faster curing time).
At a higher temperature or relative humidity the pot life is shorter.
Attation:
● Do a test on adhesive property and read the technical data sheet and MSDS before use.
● Can’t mix with other sealant, otherwise will affect the adhesion.
● The operating temperature should be at least 5℃ or above, otherwise will affect the curing time and adhesion.
Storage:
12 months stored in unopened containers in cool, dry and ventilated places.
