ABOUT:

VESTANAT® T 1890 is a cycloaliphatic polyisocyanate crosslinker with remarkably short curing cycles even at ambient temperatures.

POLYISOCYANATE CROSSLINKERS IN 2K SYSTEMS?

  • Combination with a resin component right before application

  • Reaction starts immediately after mixing the polyisocyanate with the resin component

  • Reaction leads to a 3D network with a high durability

Benefits?

  • Low viscosity

  • Excellent compatibility & high reactivity

  • Durability against environmental impacts

  • UV resistant, lightfast and very good gloss retention

  • First-class chemical resistance

  • High reactivity even at ambient temperature

  • Short curing cycles

Storage and Transportation:

STORAGE: It is recommended to store in a dry and cool area with proper ventilation.

  • Hardeners

  • Polyisocyanurate

Material?

Coatings, paints & inks?Fast curing, Weather resistant, Solventborne, Hard

 

General Characterization?

Aliphatic polyisocyanate (IPDI trimer).

As the hardener component for lightfast polyurethane coating systems and as an additive resin for alkyd spray coatings.

Storage Conditions?

– Storage in original sealed Covestro container.
– Recommended storage temperature: 0 – 30 °C.
– Protect from moisture, heat and foreign material.
General information: The product is sensitive to moisture. Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product.
