In the UV curing materials industry, poor adhesion, low flexibility, and limited weather resistance remain the three core challenges for formulators. With the rising demands of high-end manufacturing sectors such as consumer electronics, vacuum metallization (VM), and flexible displays, the market urgently needs a UV resin that delivers excellent adhesion on multiple substrates, superior flexibility, and outstanding boil resistance. T-7030, a 2-functional aliphatic polyurethane acrylate resin, is precisely designed to meet these stringent requirements.
Core Features of T-7030: From Molecular Design to Performance Breakthrough
T-7030 is a 100% solids, 2-functional polyurethane acrylate UV resin. Its molecular architecture integrates both adhesion promotion and flexibility enhancement.
For adhesion, T-7030 provides outstanding adhesion to PC (polycarbonate) substrates as well as broad and stable bonding performance on paper, plastic film, metal, and other substrates. Key technical advantages include:
Excellent boil resistance – The cured film maintains stable adhesion even after prolonged exposure to hot water.
Superior yellowing resistance – Ensures long-term appearance stability of the coating.
Outstanding chemical and solvent resistance – The cured film withstands prolonged contact with various chemical media, making it suitable for demanding applications in electronics, automotive, packaging, and more.
High flexibility and low stress design – With a glass transition temperature (Tg) of -45°C and elongation at break of 80%, this extremely low Tg provides excellent elasticity even at low temperatures, effectively preventing cracking or delamination caused by stress buildup.
In terms of flexibility and impact resistance, T-7030 has an elongation at break of 80% and a molecular weight of ~3,300. This structural feature gives it excellent encapsulation and adhesion to metal deposits in vacuum metallization processes, effectively preventing plating delamination.

Application Fields: From Vacuum Metallization to UV PSAs
Leveraging its comprehensive performance advantages, T-7030 demonstrates wide applicability across multiple high-end segments:
UV Adhesives: T-7030 can be used in UV pressure-sensitive adhesive (PSA) formulations for paper, film, and plastics. It achieves a unique balance of tack, peel strength, and cohesive strength, providing ideal bonding strength and water resistance. Moreover, T-7030 is monomer‑free and has no irritating odor, meeting both environmental and safety requirements.
UV Coatings: As a UV primer, T-7030 provides excellent adhesion to both the substrate and the subsequent plating or topcoat. Its performance in vacuum metallization processes is particularly outstanding – it not only significantly enhances plating adhesion but also shows good compatibility with UV topcoats, ensuring strong interlayer bonding.
UV Inks: T-7030 is suitable for UV screen printing inks on organic and inorganic materials. It withstands boiling water and thermal shock tests, meeting the demanding requirements of high-end ink applications such as food packaging.
Vacuum Metallization (VM) Process: When used as a basecoat resin in vacuum metallization, T-7030 not only enhances the adhesion between the metal deposit and the substrate, but also provides excellent resistance to solvent attack, ensuring the stability of the plated layer during subsequent processing and end use.
Formulation Optimization: Key Strategies for Reducing Shrinkage and Enhancing Adhesion
T-7030 is miscible with a wide range of conventional monomers. A particularly noteworthy formulation recommendation is: to reduce the volumetric shrinkage caused by high-functional monomers (which can harm adhesion), it is advisable to combine T-7030 with FM-350B methoxylated acrylate monomer. FM-350B is a monofunctional low‑shrinkage UV monomer that exhibits minimal volume shrinkage during curing, effectively avoiding substrate warpage or loss of adhesion due to shrinkage stress. Additionally, CTFA, THFA, and other monomers can also be used to lower shrinkage, enhance adhesion, and enable faster curing.
From a system compatibility perspective, T-7030 shows good miscibility with most conventional resin systems including polyesters, epoxies, polyurethanes, phosphates, and acrylates, offering formulation engineers great flexibility in design.
Future-Ready, Sustainable Performance Solutions
As global attention on environmental protection and sustainable development grows, 100% solids, solvent‑free UV resin systems are becoming the mainstream direction of the industry. T-7030 contains zero volatile organic compounds (VOCs), aligning with green manufacturing trends. Meanwhile, the global UV pressure‑sensitive adhesive market is expanding rapidly – according to a QYResearch report, the market is expected to grow at a steady CAGR from 2026 to 2032. With its unique balance of properties in UV PSA formulations, T-7030 is well‑positioned to play a key role in this fast‑growing market, providing reliable adhesive solutions for electronics packaging, medical tapes, consumer electronics, and packaging applications.
Conclusion
T-7030 is a high‑performance polyurethane acrylate UV resin that combines strong adhesion, high flexibility, excellent weatherability, and solvent‑free environmental benefits. Whether you are formulating a primer for polycarbonate substrates, a vacuum metallization basecoat requiring interlayer adhesion, or a precision UV pressure‑sensitive adhesive, T-7030 offers formulators a reliable, efficient, and continuously optimizable base material.
