LSD-01 decolorant polymer is a dicyandiamide based cationic copolymer with a medium

molecular weight. It is active with the majority of dyes used in industrial processes, it is

effective through the formation of organic complexes with the dye molecule and the subsequent

removal of the complex’s solid particles by flocculation and sedimentation.
