Key Features of T-7002 Resin
T-7002 is engineered to deliver exceptional performance across multiple domains. Its standout characteristics include:
Ultra-Low Viscosity: Enables high-load formulations without compromising flow or processability, reducing the need for excessive diluents.
Superior Flexibility: Ensures resistance to cracking and delamination, even under dynamic stress conditions.
Excellent Adhesion: Bonds strongly to diverse substrates, including PVC, PET, PC, and OPP films.
Hydrolysis Resistance: Ideal for applications exposed to moisture or harsh environments.
Non-Yellowing Properties: Maintains optical clarity and color stability over time.
Rapid Cure Speed: Supports high-throughput manufacturing with moderate energy requirements.
Applications of T-7002 Resin
1. UV-Curable Pressure-Sensitive Adhesives (PSAs)
T-7002 excels in PSAs by providing:
High Initial Tack: Immediate adhesion upon contact.
Balanced Cohesion and Adhesion: Prevents residue or lift-off during debonding.
Low Shrinkage: Minimizes stress on delicate substrates.
Typical Uses: Label films, protective tapes, and medical device assemblies.
2. UV Inkjet Inks and Printing
As a backbone resin for inks, T-7002 offers:
Pigment Wetting: Stabilizes colorants for consistent print quality.
Substrate Versatility: Reliable adhesion to plastics, metals, and treated surfaces.
Fast Drying Times: Enables high-speed roll-to-roll printing.
Ideal For: Outdoor graphics, product packaging, and decorative prints.
3. Solvent-Free UV Coatings and 3D Printing
In coatings and additive manufacturing, T-7002:
Reduces System Viscosity: Facilitates spreading or layering without sagging.
Enhances Durability: Improves scratch and chemical resistance.
Supports Complex Geometries: Maintains layer integrity in 3D-printed parts.
Formulating with T-7002: Best Practices
Diluent Selection: Combine with reactive diluents like TPGDA or ODA to adjust viscosity and Tg.
Photoinitiator Systems: Use bisacylphosphine oxide (BAPO) or α-hydroxyketone blends for deep-section cure.
Additive Compatibility: Incorporate slip agents or defoamers to enhance surface quality.
Why Choose T-7002?
T-7002 resin bridges the gap between processability and end-use performance. Its ability to reduce formulation complexity while improving key properties like adhesion and flexibility makes it a cost-effective solution for innovative UV-curable products.
