Recommended usage
It is recommended to add a catalyst of 0.5%, which can be used in 115-120degree30minutes to dry completely, but add0.5% catalyst will reduce the storage stability of the finished product, through the experimental dataIndicates that after adding 0.5%after tin catalyst at 40Continuous placement at 100°F temperature5 The daily viscosity varies greatly (40degrees a day is about25degree3Days), at 40degree placement60The 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.
