In the fields of chemicals, coatings, inks and adhesives, Tripropylene Glycol Diacrylate (TPGDA) has become one of the core raw materials of UV curing technology due to its unique chemical structure and properties. As a bifunctional acrylate monomer, TPGDA not only has low viscosity, high reactivity and environmental friendliness, but also can significantly improve the durability and processing efficiency of end products. The AM-321 product launched by Shenzhen U-Sunny is a high-performance solution developed based on TPGDA technology, setting a new benchmark for the industry.
1. Chemical properties and industrial value of TPGDA
The molecular structure of TPGDA consists of two acrylate groups connected by three propylene glycol units, which gives it excellent flexibility and curability. Its key parameters include:
CAS number: 42978-66-5
Molecular formula: C15H24O6
Water solubility: 4g/L at 20℃, suitable for water-based systems
Viscosity: 15 mPa·s (25℃), low viscosity is easy to formulate
Safety: Meets Xi/N risk identification, passes 24-37-61 safety standards, and has low skin irritation
These properties make it an ideal choice for UV-curable coatings, inks and adhesives, especially in scenarios that require fast curing, high gloss and scratch resistance.
2. Analysis of TPGDA's application in four major fields
Coating industry: TPGDA, as a reactive diluent, can reduce the viscosity of the resin system and improve the adhesion and weather resistance of the coating. For example, in automotive plastic coatings and wood coatings, its mixed system with epoxy acrylate can achieve efficient curing below 120°C and a hardness of more than 2H.
Ink technology: In flexographic printing and screen printing inks, TPGDA forms high-resolution patterns through UV curing, which is suitable for packaging materials and electronic product labels. Its curing speed is more than 3 times faster than traditional solvent-based inks.
Adhesive innovation: TPGDA, as a cross-linking agent, can enhance the shear strength of adhesives. Studies have shown that UV adhesives with 10% TPGDA can withstand 90° bending without cracking in metal-plastic bonding and can withstand alcohol wiping for 30 times.
3. Shenzhen U-Sunny AM-321: Commercial breakthrough of TPGDA technology
Shenzhen U-Sunny's AM-321 is a formula product designed for UV curing system. Its core technical advantages include:
High-efficiency curing: It can achieve surface drying within 0.5 seconds under LED low-energy light source, which is suitable for high film thickness scenes such as nail polish and plastic coating.
Environmental compatibility: By optimizing the ratio of TPGDA and photoinitiator (such as TPO, ITX), the VOC emission of AM-321 is 40% lower than that of traditional products, which complies with EU REACH standards.
Versatile adaptation: It can be formulated into transparent or colored systems with a viscosity range of 3000-5000cps, suitable for various processes such as spraying and rolling.
IV. Market Trends and Future Outlook
As the global demand for environmentally friendly materials grows, the application of TPGDA in the fields of new energy (such as lithium battery encapsulation glue) and smart devices (folding screen UV coating) continues to expand. Shenzhen U-Sunny has further improved the performance of TPGDA through the research and development of refractive index monomers such as HM-103 to meet the high-end needs of 5G base stations and electric vehicles.
Tripropylene Glycol Diacrylate is redefining the performance boundaries of chemical materials with its versatility and environmental advantages. Shenzhen U-Sunny provides sustainable and efficient solutions to global customers through products such as AM-321. In the future, with the in-depth development of TPGDA in the field of smart materials, its market potential will be accelerated.
