As the global chemical industry pursues environmental protection and high-performance materials, reactive diluents have become key additives in the fields of coatings, inks, adhesives, etc. This type of material not only optimizes construction performance by reducing viscosity, but also participates in cross-linking reactions and becomes part of the cured film, significantly reducing VOC emissions. The AM-321 acrylate monomer launched by Shenzhen U-Sunny is leading the industry's technological upgrades with its low volatility, low viscosity and balanced film-forming properties.
1. Core functions and technical characteristics of active diluents
Active diluents are integrated into the coating system through chemical bonding, and have the dual functions of viscosity adjustment and performance enhancement:
Reduce VOC emissions: replace traditional solvents and comply with environmental regulations such as EU REACH.
Improve mechanical properties: improve the flexibility, impact resistance and chemical stability of the coating by adjusting the crosslinking density of the epoxy resin.
Application diversity: suitable for water-based coatings, high solid systems and radiation curing systems, such as the rapid drying requirements of UV inks.
Taking epoxy active diluents as an example, its typical representative is p-TBGE (tert-butylphenyl glycidyl ether), which can reduce the glass transition temperature (Tg) while maintaining thermal stability, and is suitable for automotive primers and electronic packaging materials.
2. Shenzhen U-Sunny AM-321: Technical advantages and application scenarios
AM-321 (TPGDA) is a star product developed by U-Sunny for environmental protection and high efficiency. Its characteristics include:
Low volatility and low odor: reduce health risks in the construction environment and meet occupational safety standards.
Excellent dilution ability: in UV-curing coatings, only 10%-30% addition can significantly reduce system viscosity and improve spraying efficiency.
Balanced film-forming properties: the paint film has both flexibility and hardness, suitable for 3C electronic coatings, metal protective paints and packaging inks.
In the field of automotive coatings, AM-321 successfully helped a manufacturer reduce the primer thickness from 100μm to 50μm, while maintaining anti-corrosion performance and saving 20% of raw material costs.
3. Industry Trends: Growth Drivers of the Active Diluent Market
Environmental regulations drive demand: The global active diluent market is expected to grow from US$1.16 billion in 2023 to US$1.89 billion in 2032, with a compound annual growth rate of 6.3%.
The Asia-Pacific market leads the growth: The expansion of emerging economies such as China and India in the construction and automotive industries has driven the Asia-Pacific region to occupy 43% of the market share.
Technological innovation direction: Bio-based active diluents (such as cardanol modified products) and multifunctional monomers (such as aliphatic glycidyl ethers) have become the focus of research and development.
4. Typical applications of active diluents in coatings/inks/adhesives
Solvent-free epoxy floor paint: Use cardanol modified diluent to reduce the system viscosity to below 2000 mPa·s and improve water resistance.
UV curing printing ink: AM-321 works with TPO photoinitiator to achieve surface drying within 5 seconds, suitable for high-speed printing production lines.
Automotive adhesives: Use diepoxy active diluents (such as 1,4-butanediol diglycidyl ether) to increase peel strength to 15 N/mm² and temperature resistance to 150℃.
Conclusion
The technological innovation of active diluents is reshaping the competitive landscape of the chemical industry. Shenzhen U-Sunny not only responds to the call for global green manufacturing through products such as AM-321, but also provides efficient solutions for coatings, inks and adhesives companies. In the future, with the deep integration of bio-based materials and smart coatings, the application boundaries of active diluents will be further expanded.
