CAS 15625-89-5 Trimethylolpropane Triacrylate (TMPTA) For Coatings And UV Inks

Product Description

Trimethylolpropane triacrylate (TMPTA) — Description

Trimethylolpropane triacrylate (TMPTA) is a tri-functional acrylate monomer (three acrylate groups on a trimethylolpropane core). It is used to formulate UV/visible-curable and free-radical systems because it can rapidly crosslink to form durable, high–crosslink-density polymer networks.

Features

High crosslink density: Tri-functionality enables rapid curing and strong network formation.
Good mechanical strength & hardness: Commonly used to improve wear resistance, scratch resistance, and modulus in cured films.
Low shrinkage tendency (relative to some systems): Helps reduce coating defects in many formulations.
Excellent compatibility: Can be blended with other acrylates (diluent acrylates, multifunctional acrylates) to tune viscosity and curing behavior.
Versatile curing options: Common in UV-curable inks, coatings, adhesives, and 3D printing resins; also used in free-radical cure systems.
Fast photo-curing capability: Suitable for thin films and high-speed coating/printing processes.

Applications

Coatings & Varnishes

UV-curable coatings for wood, metal, plastic, and general industrial coatings
Protective topcoats and clear coats requiring hardness and chemical resistance

Inks & Screen Printing

UV inks for labels and flexible/packaging applications
Adhesive primers and surface coatings

Adhesives

UV-curable adhesives for bonding where stiffness and durability are needed

Plastics / Composite Resins

Photo-reactive resin systems for composites and castings (where permitted by formulation design)

3D Printing / Rapid Prototyping

As a component in UV-curable resin formulations (tuned via dilution and photoinitiator choice)

Surface Treatments

Lacquers and functional coatings for improved abrasion resistance and long-term performance

Packing

Drums: 25 kg, 200 kg

Intermediate bulk containers (IBCs): ~1000 kg

Storage

Store in a cool, dry, well-ventilated area.
Keep containers tightly closed to minimize oxygen exposure and moisture uptake.
Avoid heat, direct sunlight, and ignition sources.
Use clean, dry dispensing equipment to prevent contamination.
Check inhibitor/stability requirements.
