use:
colorless or light yellow transparent liquid, solid below 10℃, then semi-solid
gel catalyst, mainly used as a room temperature silicone rubber curing catalyst, especially suitable for deacetic acid type silicone products; it is characterized by a faster catalytic rate than dibutyltin dilaurate, and can be used for polyurethane elastomers and sprayed rigid polyurethane foam , hard foam high resilience molded foam, etc. in order to reduce its odor of acetic acid, 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 capped immediately after use. it is easily hydrolyzed when exposed to air, and solids precipitate out of the bottle mouth. it can also be used as a catalyst for polyurethane coatings.
storage:
it should be kept dry during storage, and the temperature should be above 10℃. the crystals are precipitated below 10℃, which will not affect the use effect after heating and melting.
transport:
store in an airtight container in a cool, dry place. the storage place must be locked, and the key must be handed over to the technical experts and their assistants. the place of storage must be far away from oxidant and water source.
general-purpose plastic and plastic-sprayed iron drums or glass containers are packaged and transported in accordance with general chemical management regulations.
package:
packing: it should be packed in glass containers, plastic containers, and metal containers resistant to chlorine corrosion, sealed and stored. store in a cool, dry place, keep the container sealed and avoid contact with oxides. do not breathe dust, avoid skin and mucous membrane contact. smoking, eating and drinking are prohibited in the workplace. after work, shower and change clothes. store contaminated clothing separately and wash it before reuse. maintain good hygiene habits.
