Blocked Isocyanate

Polyisocyanate Curing Agents/ PU Hardener

The isocyanate functional groups (-NCO) of blocked polyisocyanates are temporarily rendered unreactive. Once blocked, it can be mixed with resin without reaction until heating up to the activation temperature. Coatings or adhesives formulated with blocked polyisocyanates allow for a longer shelf life, stable storage and precise control over crosslinking process. Therefore, it finds applications in a wide range of industries including automotive finishes, construction and coil coating for can and tin package.
