Industrial grade 95% 2,3-Epoxypropyltrimethylammonium chloride CAS 3033-77-0 EPTAC

Certificate of Analysis-COA 

 Applications 

1.Reactive Cationic Etherifying Agent: Its epoxy ring reacts directly with starch, cellulose and other polysaccharides under milder conditions than chlorohydrin-type reagents, so manufacturers can build cationic grades in a straightforward, controllable reaction step.

2.Cationic Starch For Papermaking: Used to produce cationic starch for paper chemicals, where the attached quaternary ammonium groups help the wet end hold fines and fillers in the sheet, improving retention and drainage while supporting dry strength in paper and board production.

3.Cationization Of Cellulose And Guar Gum: Applied to cellulose, guar gum and other natural polymers to raise their cationic charge, which supports functional cellulose derivatives, bio-based cationic grades and downstream formulations that depend on charge density.

4.Water Treatment Flocculants: It also serves as a reagent for synthesizing cationic polymers used in wastewater clarification and sludge dewatering, supporting faster solid-liquid separation in municipal and industrial treatment plants.

5.Textile Finishing And Fiber Modification: In textile auxiliaries it cationizes fibers to improve dye uptake, antistatic properties and overall fabric performance, which helps mills reach consistent shades on cotton and other cellulosic fabrics in continuous and pad-batch lines.
