Hi-block BI-175 |
Description
Hi-block BI-175 is a blocked polyisocyanate based on hexamethylene diisocyanate
and designed for high performance coatings in a wide range of application areas.
Especially it is used for the coil coating, can coating and automotive coating
to improve the flexibility and adhesion and chipping resistance of baking coating
systems.

Advantages
- Fast cure and lower cure temperatures
- Good flexibility and adhesion
- Good chip resistance and mechanical properties
- Excellent weather stability
Applications (Powder coating)
- One component baking systems with hydroxyl functional coreactants
- Alkyds, Acrylics, Polyesters, Polyurethane and Epoxies etc.
- Coil coatings, can coatings, general industrial coatings, appliances and
automotive coatings etc.
- The cure time and temperature required are dependent upon the choice of
coreactant and catalysis.
