Store in a cool, ventilated warehouse. Stay away from the fire and heat sources. Avoid light preservation. The library temperature should not exceed 30℃. Keep the container sealed and have no contact with the air. Should be stored separately from oxidant, acid, alkali, avoid mixed storage. Equipped with the corresponding variety and quantity of fire-fighting equipment. The storage area shall be equipped with leakage.
Used in the manufacture of coatings, adhesives, fiber and fabric modification, processing AIDS, leather processing AIDS, etc. Used as a polymeric monomer for soft polymers, acting as an internal plasticizer in copolymers. Also used as a solvent.
Mainly used as a soft monomer for the manufacture of acrylate solvent-based and emulsion pressure sensitive adhesives. It is also used as the main monomer for the production of microsphere pressure-sensitive adhesive for notepad. It is also used in the manufacture of coatings, plastic modifiers, paper and leather processing AIDS, fabric finishing agents and other products.
Used for synthetic fiber fabric processing, and as adhesive (anti-invasive pressure sensitive adhesive)
