Detailed Product Description

Primer can react and solidify with moisture in the substrate material or in the 
air. It can promote the adhesion of polyurethane sealant and substrate 
materials, and can prevent the damage from ultraviolet ray. It is always used 
to accompany with cleaner in order to increase the adhesion of polyurethane 
sealant. Also, primer can be used individually if the previous test is qualified. 
Due to the variety of substrate and the difference of operating conditions, we 
suggest that a previous test should to be done for choosing a proper primer 
and related cleaner to ensure the adhesive effect.

1) One component, moisture curable
2) Fast drying speed
3) Good initial adhesiveness, high shear strength
4) No corrosion on substrate material and no penetrating pollution
5) Excellent anti-aging performance
6) Long preservation life
