Polyamine Poly (EPI-DMA)
They are organic compounds having two or more amine groups attached to them. These chemical powders & liquids are most commonly utilized for water treatment, decolorizing, and as coagulant agent for flocs. Also known as film forming amines, they are widely used in boilers and cooling systems to prevent corrosion. These compounds work by forming a hydrophobic layer on metal surface to provide protection against corrosive species. They also possess crystal modifying property and helps in preventing scaling of heat exchange surface. In food industry, these polyamines work by promoting cross-linking of unreacted amines for decoloration purpose.
