Borchi^® Kat 315

• Replacement for other polyurethane catalysts, especially for amines and tin-based products like DBTL
• Accelerates the reaction between the polyol and isocyanate component of polyurethane foam systems
• Ensures fast blocking stability
• Earlier solvent resistance and sanding capability
• Higher film hardness

• Solvent-based and solvent-free pigmented one- and two-component polyurethane coatings
  • Automotive Refinish
  • General Industrial
  • Coil

The recommended addition rate of Borchi^® Kat 315 in polyurethane coatings is according to our experience between 0.01 and 0.12% product, calculated on solid binder. The exact amount depends on the used binder and should be determined by means of preliminary trials. The optimal addition rate of Borchi^® Kat 315 in PU foams and RTV silicone resins is depending on the reactive components and should as well be determined by means of preliminary trials. Borchi^® Kat 315 can be added either in the supply form or diluted (e.g. in butyl acetate) to the polyol component of the coating System. Borchi^® Kat 315 should not be diluted below 10% of the supply form, since those solutions are only stable for a limited period of time.

Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product.
