1. Industry trends and market drivers
The global ceramic ink market is expected to grow from $2.82 billion in 2025 to $3.94 billion in 2030 (CAGR 6.89%), with ceramic tile applications being the fastest growing area. This growth stems from the upgrading of architectural decoration demand, and consumers' requirements for the durability, color persistence and complex pattern design of tiles have significantly increased. At the same time, the UV curing ink market is also booming, with a scale of $12.93 billion in 2032 (CAGR 10.72%), and environmental protection policies have promoted water-based and low-VOC technologies to become the core direction.
2. Technical pain points: Challenges of shrinkage to printing accuracy
Traditional UV inks shrink in volume due to molecular cross-linking during curing (the shrinkage rate of trifunctional monomers can reach 4.36%), resulting in pattern deformation and decreased adhesion in ceramic printing. Especially in precision inkjet printing, shrinkage can cause microcracks and color deviations, affecting product yield. In addition, the rheological properties of inks (such as viscosity and thixotropy) directly affect printability, and the pigment dispersion structure needs to be regulated by dynamic viscoelasticity.
3. Solution: Innovative advantages of T-7131 low shrinkage UV resin
T-7131 trifunctional polyurethane UV resin from Shenzhen U-Sunny has achieved technological breakthroughs through molecular structure design:
Ultra-low shrinkage: more than 50% lower than the shrinkage of traditional resins, curing energy only requires ≥500mJ, ensuring pattern size stability;
Excellent adhesion: 100-grid test on glass, ceramic, and metal substrates reaches the highest level, without the need for coupling agent assistance (;
Improved weather resistance: excellent resistance to boiling water, no peeling after long-term immersion, and adaptable to high temperature and high humidity environments;
Formula compatibility: can be used with difunctional resins (such as Trust 7128) compounding to optimize the binding force on inorganic materials.
4. Collaborative application of adhesives and pressure-sensitive adhesives
In the ceramic UV printing industry chain, the performance of supporting materials directly affects the terminal effect:
UV adhesives: used for composite bonding of ceramics and metals, must meet the requirements of high strength, chemical resistance and fast curing;
UV curing pressure-sensitive adhesives: alternatives to solvent-based products, with the advantages of no VOC emissions and low-temperature curing, suitable for ceramic label printing.
5. Certification standards and sustainable development
Ceramic UV inks must pass RoHS, EN71 (EU), ASTM (USA) and China environmental certification, limiting the content of heavy metals and migratable substances. T-7131 resin complies with the ISO9001 system, helping customers meet global market access requirements.
6. Conclusion: Technology empowers future manufacturing
With the penetration rate of digital printing exceeding 95%, low shrinkage UV resin will become the core material for high-precision ceramic decoration. Shenzhen U-Sunny's T-7131 uses the dual engines of technological innovation + environmental compliance to drive the industry to evolve towards efficiency and greenness.
The high reactivity and low shrinkage characteristics of T-7131 can simultaneously improve the dimensional accuracy and durability of the adhesive system.
