Dosage

The recommended addition rate of Borchi® Kat 315 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 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.
