Description

FA-367 is a water-soluble high molecular weight amphoteric copolymer with different branches bearing various anionic, cationic and nonionic groups on its acrylic main chain. It is a high-agent to deal with the mud. Easily to solute in water, the rate of absorption is very fast in the clay surface, strongly coating, salt-resistant, calcium-resistant, relatively low cost and so on.
