Production Description：
JHSW-8450 Polyurethane Primer is a polyurethane primer independently developed by Qingdao Polyswell Technology Co,Ltd,. JHSW-8450 has good permeability to concrete, metal and other substrates, and increases the adhesion between the substrates and polyurea. It can also be used as an interlayer binder to increase the adhesion between the old and new polyurea coatings.
Advantages：
1. Low density, good permeability to concrete, metal and other substrates
2. Significantly improve the adhesion of polyurea to concrete, metal and other substrates
3. can be used in wet substrate and low temperature environment with strong environmental adaptability
4. Simple construction, low consumption, cost saving
Recommended Uses:
a) Can be used for concrete, metal and other substrate surface to increase the adhesion of the substrate and polyurea;
b) As a transfer paint can increase the adhesion between the old and new polyurea.
