Physical Properties of Tripropylene Glycol Diacrylate (TPGDA)

Tripropylene Glycol Diacrylate, known as TPGDA and identified by CAS number 42978-66-5, is a chemical raw material valued for its versatile applications and remarkable physical properties. TPGDA is a clear, colorless liquid with a faint, characteristic odor. It has a density of about 1.02 g/cm³ at 20°C and a boiling point of approximately 235°C. The viscosity of TPGDA is around 10-15 mPa·s at 25°C. Thanks to its two acrylate groups, TPGDA exhibits high reactivity and enables efficient cross-linking reactions, especially under UV irradiation. These properties make it an important component in various industrial applications.

Applications of Tripropylene Glycol Diacrylate (TPGDA)

One of the primary applications of TPGDA is the production of UV-curable coatings. Due to its high reactivity, TPGDA allows for rapid curing under UV light, resulting in durable and long-lasting surfaces. These coatings are used in the automotive and electronics industries, providing protection against mechanical and chemical influences.

TPGDA is widely used in the production of UV-curable printing inks. It enhances ink adhesion on various substrates and ensures rapid curing, increasing production speed and efficiency. This characteristic is particularly beneficial for printing on plastics, metals, and paper, where quick and durable ink adhesion is essential.

In the adhesive industry, TPGDA is used as a reactive diluent and cross-linking agent in UV-curable adhesive systems. The quick curing time and strong bonding properties of TPGDA contribute to the efficiency and quality of adhesive applications, which are crucial in electronics, construction, and packaging industries.

In the field of 3D printing, TPGDA 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, technical components, and medical models, where precision and material strength are critical.

Tripropylene Glycol Diacrylate (TPGDA, CAS No. 42978-66-5) is a versatile chemical raw material with excellent physical properties. Its wide applicability ranges from UV-curable coatings and printing inks to adhesives and 3D printing. The unique properties of TPGDA make it an indispensable component in many industrial processes and products, where efficiency and performance are essential.
