polysulfide sealant

 

 

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.
