Key Applications

GTMAC / EPTAC is a highly reactive cationic etherifying agent due to its epoxy group, allowing efficient cationization of natural polymers even under milder reaction conditions compared to chlorohydrin-type reagents. related Cationic Etherifying Agents

• Direct cationization of starch for paper chemicals: Widely used to produce high-performance cationic starch for retention, drainage and strength improvement in papermaking processes.

• Cellulose and polysaccharide modification: Applied for the cationization of cellulose, guar gum and other natural polymers to enhance their functionality in industrial applications.

• Water treatment and flocculation polymers: Serves as a key reagent for synthesizing cationic polymers used in wastewater clarification and sludge dewatering.

• Textile auxiliaries and functional finishes: Enables efficient cationization of fibers to improve dye uptake, antistatic properties and overall fabric performance.

• Specialty chemical and polymer synthesis: Functions as a reactive intermediate for preparing other quaternary ammonium compounds and cationic materials in specialty synthesis.
