Physical Properties of Trimethylolpropane Triacrylate (TMPTA)

Trimethylolpropane Triacrylate, known as TMPTA and identified by CAS number 15625-89-5, is a chemical raw material with remarkable physical properties. TMPTA is a colorless to slightly yellow liquid with medium viscosity. It has a melting point of approximately -15°C and a boiling point of around 225°C. The density of TMPTA is about 1.10 g/cm³ at 20°C. This compound is known for its high reactivity and good solubility in many organic solvents. The chemical structure of TMPTA, which contains three acrylate groups, enables rapid and efficient cross-linking reactions under UV or electron beam irradiation.

Applications of Trimethylolpropane Triacrylate (TMPTA)

TMPTA is widely used in the production of UV-curable coatings. Due to its high reactivity, TMPTA allows for rapid curing under UV light, resulting in hard, durable, and chemical-resistant surfaces. These properties make it ideal for applications in the wood and furniture industry as well as the automotive sector, where high-quality and long-lasting coatings are required.

Another significant application of TMPTA is in the manufacture of UV-curable printing inks. TMPTA improves ink adhesion on various substrates and ensures rapid curing, which increases printing speed and production efficiency. This characteristic is particularly beneficial for printing on plastic, metal, and paper, where quick and durable ink adhesion is necessary.

TMPTA is also widely used in the adhesive industry. It is particularly employed in reactive hot melt adhesives and UV-curable adhesive systems. The quick curing time and strong bonding properties of TMPTA contribute to the efficiency and quality of adhesive applications, which are essential in electronics, construction, and packaging materials.

In the field of 3D printing, TMPTA is used as a component in photopolymers. Its excellent cross-linking ability results in stable and detailed print outcomes. This is especially useful for producing prototypes, jewelry, and medical models, where precision and material strength are crucial.

Trimethylolpropane Triacrylate (TMPTA, CAS No. 15625-89-5) is a versatile chemical raw material with outstanding physical properties. Its application possibilities range from UV-curable coatings and printing inks to adhesives and 3D printing. This versatility and the specific benefits it offers make TMPTA an indispensable component in many industrial processes and products.
