Gel catalyst, mainly used as room temperature silicone rubber curing catalyst, especially suitable for deacetic acid type silicone products; its characteristic is that the catalytic speed is faster than dibutyltin dilaurate, and it can be used for polyurethane elastomers, spray hard polyurethane foam plastics, hard foam high resilience molded foam, etc. In order to reduce its acetic acid smell, it can be used in combination with dibutyltin dilaurate, usually using dibutyltin diacetate: dibutyltin dilaurate at a ratio of 1:9 or 2:8. This product should be immediately capped after use, it is easily hydrolyzed when exposed to air, and solids precipitate from the bottle mouth. It can also be used as a polyurethane coating catalyst.
