use
Gel catalyst, mainly used as room temperature silicone rubber curing catalyst, especially for deacetic acid type silicone products; characterized by faster catalytic speed than dibutyltin dilaurate, can be used for polyurethane elastomer, sprayed rigid polyurethane foam , hard foam high rebound molding foam, etc. In order to reduce its acetic acid odor, it can be used in combination with dibutyltin dilaurate, usually using dibutyltin diacetate: dibutyltin dilaurate is 1:9 or 2:8. This product should be tightly closed immediately after use. It is easily hydrolyzed when exposed to air, and solids are precipitated at the mouth of the bottle. It is also used as a catalyst for polyurethane coatings.

Store
It should be kept dry during storage, and the temperature should be above 10 °C. Crystals are precipitated below 10 ° C, and the effect of use is not affected after heating and melting.
