purpose
Used in chemical, textile, printing, paper, leather, agriculture, food, medicine, packaging, ceramics, electronics, cosmetics, construction and other industries. It is mainly used as binder, textile auxiliaries, paper auxiliaries, cement additives, emulsifiers, dispersants, etc. Adding water-soluble PVA into putty powder can improve bonding force and prevent cracking and dropping powder as emulsifying stabilizer of PVAc emulsion polymerization. Used for the manufacture of water-soluble adhesives. Used as a modifier for starch Adhesive. It can also be used for the preparation of sealant for photosensitive adhesive and benzene resistant solvent. Also used as release agent, dispersant and so on.
