The demand for UV-curable coatings, inks, and adhesives on flexible materials like TPU and PVC is rapidly growing across industries. However, this trend presents a unique challenge: how to achieve exceptional elongation and flexibility without compromising on adhesion, scratch resistance, and cure speed. T-7020 resin is the innovative, high-performance solution specifically formulated to meet these demanding requirements.
Addressing the Pain Points of Coating Flexible Materials
Traditional UV resins often fail on elastic substrates, leading to cracking, poor adhesion, and inadequate flex endurance. T-7020 resin breaks this paradigm with its unique chemical design, masterfully balancing high flexibility with robust mechanical strength, making it the ideal choice for soft and pliable surfaces.
Core Performance Advantages of T-7020 Resin
1. Exceptional Flexibility & Elongation:
Designed for substrates that bend, stretch, and flex. Coatings remain intact under deformation, making it perfect for dynamic applications like wearables, flexible films, and soft-touch packaging.
2. Rapid Cure & Excellent Surface Dry:
Features faster reaction kinetics for increased production throughput. Quick surface dry minimizes dust pickup and handling damage during processing.
3. Superior Adhesion & Durability:
Delivers outstanding cross-cut adhesion on challenging surfaces like TPU and PVC. Its high scratch resistance ensures long-term durability and product integrity.
4. Excellent Chemical Resistance:
Withstands erosion from common solvents, maintaining performance and appearance in harsh environments.
Key Formulation Advice: Enhance Performance with EOEOEA Monomer
T-7020 resin exhibits excellent compatibility with a wide range of standard monomers, offering formulators significant flexibility. For applications requiring maximum elongation and flexibility, we highly recommend combining T-7020 with low glass transition temperature (Tg) monomers such as EOEOEA (Ethoxyethoxyethyl acrylate).
This combination creates a powerful synergistic effect:
Further reduces internal stress, minimizing the risk of cracking in thick coatings.
Enhances through-cure efficiency, ensuring complete polymerization even in deeper sections.
Maintains low shrinkage, preserving long-term adhesion on flexible bases.
