DXB-3465 IPDI-Based Blocked Aliphatic Isocyanate Crosslinkers

DXB-3465 is a solvent-based blocked aliphatic polyisocyanate crosslinking agents based on Isophorone diisocyanate. It is used as the hardener component to formulate lightfast, one-component (1K) polyurethane coatings.

Features

  • Weathering resistance
  • Light color & Low odor
  • Excellent compatibility
  • Stable storage

Applications

As the hardener in the formulation of single-component polyurethane baking coating, particularly in coatings designed for can and tin packaging applications. It can also as an additive in drying systems to provide enhanced flexibility and adhesion.
