Primary Applications

1. UV Coatings for Vacuum Plating (Base Coat)

Use Case: Premium vacuum metallization on glass bottles (perfume, wine), cosmetic packaging, and metal decorative parts.

Value Proposition: Provides the essential foundation for plating: superior primer adhesion and exceptional water boil resistance, ensuring the metal layer remains bright and intact.

2. UV Curing Adhesives

Use Case: High-performance structural bonding and assembly for glass-metal, ceramic-metal, and glass-glass combinations.

Value Proposition: Fast curing, high bond strength, low shrinkage, and excellent water resistance for demanding applications.

3. UV Curable Inks

Use Case: Durable label printing (e.g., beverage labels requiring ice water resistance), screen printing on electronics glass/metal housings, ITO film circuits.

Value Proposition: Dramatically enhances ink adhesion on non-absorbent inorganic substrates. Fast curing and good chemical resistance, even in highly pigmented systems.

Performance Benefits

Proprietary "No Pre-Treatment" Technology: Its ultra-low acid value and specialized molecular structure allow it to wet and bond directly to inert surfaces, saving time and cost on pre-treatment steps.

Enhanced Water Boil Resistance: An improved version of T-7130, this resin is engineered to retain adhesion and flexibility after exposure to high heat and humidity (e.g., water boiling, vapor deposition), ensuring reliability.

Expert Formulation Guidance: For optimal performance in specific applications:

For Vacuum Plating Base Coats: Combine with AM324 Monomer to reduce shrinkage, increase cure speed, and prevent plating haze.

For Demanding Adhesive Bonds: Combine with FM-350B Monomer to minimize volumetric shrinkage and maximize final adhesion strength.
