WD-8100 Water-based Isocyanate Crosslinkers

Hydrophilic aliphatic polyisocyanates crosslinking agents based on HDI (hexamethylene diisocyanate). It can be served as the hardener/curing agent for water-dispersible polyurethane coatings or adhesives.

Features

  • High hardness
  • Easy to emulsify
  • Zero VOC
  • High gloss
  • High fullness
  • Excellent chemical resistance

Due to its compatibility with water-based systems and reduced VOC emissions, WD-8100 serve as a versatile curing agent for waterborne polyurethane coatings in applications including industrial and floor paints.  Besides, it can also used for adhesives to improve the physical properties, such as increasing bond strength and heat resistance.
