1. Core characteristics and industry value of UV Curable TPGDA
UV Curable TPGDA (tripropylene glycol diacrylate) is a benchmark material for bifunctional active monomers in the field of photocuring. The unique branched alkyl polyether skeleton in its molecular structure gives it three core advantages:
Low viscosity and high dilution capacity (viscosity 10-15cps), which can significantly reduce the viscosity of the resin system and improve processing fluidity
Fast curing and low shrinkage, the cured film has excellent flexibility, and the shrinkage rate is only 18%, which is much lower than the 19% of the similar monomer HDDA
Low skin irritation and environmental protection, in line with EU REACH and other regulatory requirements, suitable for medical devices, cosmetics and other safety-sensitive fields.
In the chemical industry, TPGDA has become a key component in UV coatings, inks, and adhesives. The global market size is expected to exceed US$560 million in 2025.
2. Analysis of three major application scenarios of TPGDA
1. Coatings: from industrial protection to high-end decoration
Wood coatings: as a cross-linking agent to improve the scratch resistance of the coating film, suitable for furniture, floors and other scenes, the curing speed is 3 times faster than traditional solvent-based coatings;
Plastic substrate coatings: in the surface treatment of automotive parts, TPGDA can enhance adhesion and reduce curing energy consumption.
2. Ink formula: the driving force of innovation in printing technology
Offset printing and flexographic printing: adding 10-15% TPGDA can reduce the viscosity of the ink by 40%, while maintaining the clarity of the dots and solving the problem of blurred printing;
3. Shenzhen U-Sunny AM-321: TPGDA optimization and upgrade solution
AM-321 (TPGDA-based modified monomer) launched by Shenzhen U-Sunny Technology has achieved three major breakthroughs based on the traditional formula:
Performance balance: glass transition temperature (Tg) and dilution capacity are balanced, suitable for high-precision coatings and ink systems;
Economic improvement: reduce raw material costs by 15% through process optimization while maintaining low volatility (VOC<50ppm);
Application expansion: Added compatibility with electron beam (EB) curing, which can meet the sterilization requirements of special scenarios such as medical devices.
