Dosage

The recommended addition rate of Borchi® Kat 315 EU in polyurethane coatings is according to our experience between 0.01 and 0.03% 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 EU 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 EU 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 EU should not be diluted below 10% of the supply form, since those solutions are only stable for a limited period of time.

Properties

Accelerates solvent-based or solvent-free one- and two-component polyurethane systems and stoving enamels based on blocked isocyanates Ensures fast blocking stability of polyurethane coatings Provides increased film hardness, earlier solvent resistance and allows earlier sanding of the applied coating Ecologically safe replacement for other polyurethane catalysts, especially for amines and tin-based products like DBTL Can be used as a tin replacement
