Hexamethylene Diisocyanate (HDI) and Isophorone Diisocyanate (IPDI) are key building blocks used in the synthesis of resins, sealants and elastomers.

Aliphatic: Hexamethylene diisocyanate(HDI)

Cycloaliphatic: Isophorone diisocyantae(IPDI)


Solvent-based and Solvent-free – Aliphatic Isocyanates

Vencorex’s Tolonate™ aliphatic polyisocyanates offer exceptional durability very good flexibility and extensive possibilities to formulators.

As crosslinkers of polyurethane coatings, they ensure:

Outstanding appearance

Exceptional gloss retention

Fast drying possibilities

HDI Biuret

HDI Trimmer (Nullate)

HDI Allophanate

HDI Polymer  Tolonate™ XF 800 is a solvent free and low viscosity aliphatic polyisocyanate based on HDI.

・Tolonate™XF 800

Tolonate™ XF 800 gives the perfect balance between hardness and flexibility. It provides excellent impact resistance, high scratch resistance and superior adhesion.


・Tolonate™XF 450

The new Tolonate™ XF 450 has been specifically designed by Vencorex to provide elasticity to your coatings while maintaining high hardness. It is especially suitable for fast drying formulations like aliphatic polyureas and polyaspartics, where it will overcome their brittleness and provide extended pot-life.

Tolonate™ XF 450 is a very versatile polyisocyanate that can be used alone or in combination with other hardeners, to effectively fine-tune the
