Stabilizer FT- 221C. is a stabilizer for textile bleaching process.
Key Features
● Concentrated product
● High cost performance
Benefits
● Chelating and dispersing properties in one. Complexes with heavy metal ions to disperse, reduce or cancel hydrogen peroxide decomposition and catalysis, effectively controls hydrogen peroxide decomposition rate.
● Effectively controls hydrogen peroxide decomposition, decreases the risk of breaking holes and strength loss after peroxide bleaching.
● Non-silicone stabilizer, silicone scale free.
● Can effectively improve utilization rate of hydrogen peroxide, improves whiteness of fabric after peroxide bleaching.
● Good compatibility with alkali, peroxide, scouring agent and other anionic and nonionic agents.
Cannot be used together with cationic, zwitterionic agents.
