HDX-60H Non-Yellowing&Fast Drying PU Hardener

HDX-60H is an aromatic/aliphatic polyisocyanate PU hardener based on toluene diisocyanate (TDI) and hexamethylene diisocyanate (HDI). It can be used as the hardener component for two-component polyurethane coatings that are both fast drying and yellowing resistant. Form supplied is approximarely 60% in Butyl/Ethyl acetate.

Features

  • Non-yellowing
  • Fast drying
  • Light color & Matte finish
  • Excellent chemical resistance

Applications

Specifically formulated for indoor and wood coating applications, HDX-60H PU hardener provides superior protection against yellowing. With its fast drying and early sandability properties, polyurethane coatings formulated with HDX-60H can help maintain consistency in the wood finishing, ensuring a smoother and more uniform finish on wood surfaces. HDX-60H features equivalent performance with desmodur HL BA.

  • Solvents containing reactive groups (e.g. water. alcohols, amines) should not be used since they react with the PU hardener. It is recommended to use “urethane grade” solvent for the dilution (with water content below 500 ppm) , and aim for a minimum of ≥25% solid content after dilution.
  • HDX-60H is sensitive to moisture. Care should be taken to use or split charging to avoid the vapor. It must be sealed tight after use up as soon as possible.
  • The product should be placed in a cool, dry indoor environment at room temperature (0-30°C), protected from direct sunlight and other chemical materials.
  • The shelf life is up to 6 months if it is stored in its sealed original drums.

HDX-60H is to used with our PU hardener together, recommended to use 5% to 50% according to the formula. This product should not be used as a standalone component.
