1. Key Product Features
T-7080 is a high‑molecular‑weight, high‑viscosity UV resin with low functionality. Its main features include:
Fast curing speed: Achieves rapid surface and through curing despite low functionality, suitable for high‑throughput production lines.
Excellent leveling: Produces smooth coating surfaces, reducing defects such as orange peel and cratering.
Low curing shrinkage: Lowers internal stress, improving adhesion stability on plastics, leather, and other substrates.
Toughness and flex resistance: Cured films combine hardness and flexibility, withstanding repeated bending without cracking.
Chemical resistance: Good resistance to common solvents, cleaners, and chemicals.
Scratch and abrasion resistance: Moderate surface hardness resists daily wear.
Monomer‑free, low odor: Minimizes volatile irritants, ideal for odor‑sensitive applications (e.g., nail products).
2. Main Applications
2.1 UV Coatings
T-7080 is widely used in protective coatings for plastics and coil materials.
TPU coatings: With suitable monomers, it forms a tough protective layer on TPU substrates, providing strong adhesion and flex resistance.
PVC coils: Offers excellent adhesion and scratch resistance for soft PVC flooring and synthetic leather, while reducing curing shrinkage to minimize coil deformation.
General plastic coatings: Suitable for ABS, PC, and similar substrates, balancing protection and aesthetics.
For surfaces that require toughness and chemical protection (e.g., electronic device housings, automotive interior parts), T-7080 can be used as the main resin or a modifying resin.
2.2 UV Adhesives
T-7080 performs well in gel nail systems.
Gel top coat: Excellent surface drying, yielding a smooth, glossy finish with long‑lasting scratch and abrasion resistance.
Builder gel systems: Monomer‑free and non‑irritating, suitable for prolonged contact with natural nails.
It can also be used in electronic or craft adhesives where low odor and high toughness are required.
2.3 UV Inks
T-7080 has very high viscosity and high molecular weight, making it suitable for specialized ink formulations.
3D textured inks: High viscosity allows ink stacking and shape retention after curing.
LED low‑energy curing inks: Cures well under low‑energy exposure, reducing equipment energy consumption.
3. Formulation Recommendations
T-7080 is miscible with a wide range of conventional monomers. For soft coil coatings or TPU coatings, AM‑312 (EOEOEA monomer) is recommended. Combining T-7080 with AM‑312 provides the following benefits:
Further reduces curing shrinkage and internal stress;
Enhances adhesion to soft substrates;
Improves coating flexibility, preventing cracks during bending.
In practical formulations, adjust the ratio of T-7080 to AM‑312 according to the target viscosity and curing speed, and use an appropriate photoinitiator (e.g., TPO, 184).

5. Summary
T-7080 resin balances low functionality with high curing speed, offering toughness, low shrinkage, chemical resistance, and scratch/abrasion resistance. Whether in TPU/PVC coatings, gel top coats, or low‑energy LED inks, it delivers reliable performance. Combining with AM‑312 monomer further improves flexibility and adhesion. For UV‑curable systems requiring low odor, strong adhesion, and flex resistance, T-7080 is a worthwhile candidate.
