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.
