uses:
colorless or light yellow transparent liquid, below 10 ℃ is solid then semi-solid
gel catalyst, mainly used as room temperature silicone rubber curing catalyst, especially for deacetic acid type silicone products; its characteristic is that the catalytic speed is faster than dibutyltin dilaurate, it can be used in polyurethane elastomer, sprayed rigid polyurethane foam, hard foam high resilience molded foam, etc.. in order to reduce its acetic acid odor can be used in conjunction with dibutyltin dilaurate, usually adopts dibutyltin diacetate: dibutyltin dilaurate is 1:9 or 2:8. this product should be capped immediately after use, it is easy to hydrolyze when exposed to air, and solid precipitated at the mouth of the bottle. it is also used as a catalyst for polyurethane coatings.
storage:
storage should be dry, temperature above 10 ℃ is preferred. below 10 ℃ precipitated crystals, heating melting does not affect the use of the effect.
transportation:
store in sealed containers and in a cool, dry place. the storage place must be locked and the key must be given to the technical experts and their assistants for safekeeping. the storage place must be kept away from oxidizing agents and away from water sources.
packed in general-purpose plastic and sprayed iron drums or glass containers and transported in accordance with general chemical management regulations.
packaging:
packing: it is preferable to use glass containers, plastic containers, chlorine corrosion-resistant metal utensils to contain, sealed and stored. store in a cool and dry place, keep the container sealed and avoid contact with oxides. do not inhale dust, avoid contact with skin and mucous membranes. smoking, eating and drinking are prohibited in the workplace. after work, shower and change clothes. store contaminated clothing separately and wash before use. maintain good hygiene practices.
