Full Name & Product Positioning
Full Name: PANGAO TLC-40/43 UV-Specialty Modified Vinyl Chloride-Vinyl Acetate Copolymer Resin
Low molecular weight specialty modified binary VC-VAc copolymer industrial resin, approximately 60% vinyl chloride, 40% vinyl acetate, and about 1% third monomer. Soluble in UV reactive monomers (such as HDDA, TMPTA, etc.) with colorless and transparent solutions. Suitable for UV wood coatings, UV inks, UV varnishes, UV coatings, and other UV-curable system formulations.

Core Advantages
1. Soluble in UV reactive monomers, allowing reduction or replacement of organic solvents in formulations, lowering solvent residue.
2. Solutions in UV systems can be colorless and transparent, with limited impact on film gloss.
3. Provides pigment wetting and dispersing assistance, supporting color development in UV ink systems.
4. Provides adhesion improvement for substrates such as PET, suitable for UV primers and UV ink formulations.
5. Good powder flow properties for convenient feeding operations.
Main Application Areas
Core Applications: UV inks, UV wood coatings, UV varnishes, UV coatings
Suitable Areas: UV wood primers, UV plastic coatings, UV packaging inks, UV overprint varnishes
Not Recommended: Pure water-based systems, food contact products, pure solvent-based high-solids topcoat main resin (non-UV systems).
