Recommendations for use
Recommended addition 0.5%The catalyst can be used in115-120 degrees30 minutes to dry completely, but add 0.5% of the catalyst will reduce the storage stability of the finished product According to the experimental data, after adding 0.5% after the tin catalyst at 40 Continuously placed at 100 degrees Celsius5 Day-to-day viscosity varies greatly (40 One day is about 25 degree3 days), at 40 degree placement60 The viscosity changes slightly every day, so it is recommended that if the goods need to be stored for a long time, adding a catalyst before use can better ensure the storage stability of the product.
