What is Methacrylatoethyl trimethyl ammonium chloride?
Methacrylatoethyl trimethyl ammonium chloride (CAS 5039-78-1), commercially known as METAC, is a cationic quaternary ammonium monomer used as a reactive building block in polymer synthesis.
Where is Methacrylatoethyl trimethyl ammonium chloride used?
- Paper manufacturing: retention aids and wet-strength additives that improve fiber bonding and filler retention
- Textiles: cationic polymers that improve dye uptake and adhesion on negatively charged fibers
- Leather processing: cationic fixatives and surface treatment agents
- Plastics and polymers: comonomer in superabsorbent networks and antistatic coatings
- It introduces permanent positive charge into polymer chains for cationic polyelectrolytes and functional coatings.
Commercial specifications
- Aqueous solution at 75–80% active content
- Packaging from drums to IBC totes for bulk procurement
