In the field of 3D printing resins, UV-curable coatings and adhesives, tripropylene glycol diacrylate (TPGDA) has become a core material in the industry due to its unique chemical properties. As the core component of AM-321, a star product of Shenzhen U-Sunny, TPGDA is redefining the application standards of the chemical, coating and ink industries through innovative processes and performance optimization.
1. Chemical properties of TPGDA and technological breakthroughs of AM-321
TPGDA is a bifunctional acrylate monomer with a molecular formula of C₁₅H₂₄O₆ (CAS 42978-66-5), which has low viscosity (10-15 cps@25℃), high reactivity and excellent film-forming properties.
Shenzhen U-Sunny's AM-321 product:
Low volatility: Reduce VOC emissions during the production process and comply with environmental regulations
Low odor: Improve operational safety and is suitable for closed workshop environments
Balanced performance: Balanced glass transition temperature and dilution capacity, suitable for a variety of resin systems.
2. Multi-scenario application of AM-321 in the industrial field
3D printing resin:
AM-321, as a photocurable monomer, can significantly reduce the viscosity of the resin system and improve printing accuracy. Its fast curing characteristics (ultraviolet/electron beam triggering) support the molding of complex structures and are suitable for the manufacture of precision molds and medical devices.
Coatings and inks:
Wood coatings: give the paint film flexibility and water resistance, solving the problem of easy cracking of traditional coatings
Plastic substrate coatings: excellent performance in automotive interior parts, with adhesion up to ASTM D3359 standard
Offset ink: Compared with TMPTA, the viscosity of the ink prepared by AM-321 is reduced by 40%, and the printability is better
3. Adhesives and sealants:
As a cross-linking agent, AM-321 can replace hydroxymethyl acrylamide, reducing the dosage by 30% while improving the bonding strength, which is suitable for electronic component packaging and PCB solder mask process.
3. Safety and sustainable development practices
Shenzhen U-Sunny strictly follows the ISO 14001 environmental management system, and the production of AM-321 adopts a closed-loop process throughout the process:
Toxicity control: Acute oral toxicity LD₅₀>1694 mg/kg (rat), in line with EU REACH standards
Waste treatment: Through esterification reaction neutralization technology, the wastewater COD value is achieved <50 mg/L
Inhibitor optimization: Hydroquinone monomethyl ether (MEHQ) addition amount ≤300 ppm, extended storage stability.
As an innovator in the field of 3D printing resins and UV curing, Shenzhen U-Sunny's AM-321 product is promoting the transformation of the coating, ink and adhesive industries towards high efficiency and environmental protection through the in-depth development of the TPGDA chemical system.
