Trimethylolpropane Triacrylate (TMPTA)

CAS#: 15625-89-5
Synonyms: TMPTA

Trimethylolpropane Triacrylate (TMPTA) is a clear, trifunctional acrylate monomer renowned for its excellent cross-linking ability, hardness, and chemical resistance. TMPTA is widely used in UV-curable coatings, inks, and adhesives, delivering durable, rigid, and highly cross-linked polymer networks.

Key Features:

• Provides high cross-link density for enhanced mechanical strength

• Imparts hardness, chemical, and solvent resistance

• Compatible with other acrylate and methacrylate monomers for copolymerization

• Excellent UV-curing efficiency and rapid polymerization

• Suitable for UV/EB-curable, thermoset, and specialty resin systems

Applications:

• UV-curable coatings for industrial, automotive, and decorative use

• UV/EB-curable inks and printing applications

• Structural and pressure-sensitive adhesives

• High-performance acrylic resins and composites

• Specialty films, coatings, and protective finishes
