Applications & Uses

Applications
  • Highly reactive hydroxy acrylic resin intended for crosslinking with isocyanate resins with a fast build-up of hardness.
  • Used for room temperature drying or forced drying of two-pack systems for automotive refinishing (top and clear coats) with excellent mechanical properties and superior outdoor durability.
  • Appropriate for high solids system at spraying viscosity.
  • Crosslinking with aliphatic isocyanates is recommended for the formulation of non-yellowing finishing. Physical drying can be accelerated with the addition of CAB resins.
