Adhesion-Enhancing Resin (PET Substrate) E1207 Adhesion PET Packaging Sector
Adhesion-enhancing resin (PET substrate) incorporates functional groups (e.g., epoxy groups, amino groups) designed to interact strongly with hydroxyl and ester groups on the PET substrate surface through molecular structure engineering. while optimizing the resin's film-forming properties to achieve tight bonding with the PET substrate. This significantly enhances the adhesion strength between subsequent functional layers (such as printing inks, laminating adhesives, and functional coatings) an

III. Product Characteristics:
Exceptional Adhesion: Demonstrates extremely strong and durable bonding to PET substrates, achieving adhesion strength at the substrate failure level. Completely eliminates issues of paint peeling and delamination.
Superior Transparency and Low Yellowing: Forms a clear, transparent film that does not compromise the inherent high transparency of PET substrates. Exhibits excellent resistance to yellowing, making it suitable for applications with stringent aesthetic requirements.
Broad Compatibility: Compatible with various resin systems including chlorinated vinyl, polyurethane, and polyester resins, facilitating easy integration into existing formulations.
Exceptional Process Adaptability: Suitable for high-speed gravure printing, roller coating, spray coating, and other processes. Excellent flow properties ensure no impact on production efficiency.
IV. Product Applications:
PET Packaging Applications: Used as a pre-printing primer for PET films (e.g., food packaging films, cosmetic PET bottles) to enhance adhesion between solvent-based, water-based, or UV inks and PET substrates, preventing print scratching, peeling, and bleeding. Also serves as substrate treatment before laminating PET with PE, aluminum foil, etc., strengthening adhesive bonding to PET and preventing packaging delamination.
PET Electronics Field: Suitable for surface treatment of PET flexible circuit board substrates and PET electronic label substrates. Improves bonding strength between conductive coatings (e.g., silver paste coatings) and insulating coatings with PET substrates, ensuring stable conductivity and insulation performance of electronic components.
PET Optical Applications: Serves as a primer for functional coatings on PET optical films (e.g., polarizer base films for LCDs, optical protective films), improving adhesion strength between scratch-resistant coatings, anti-glare coatings, and PET substrates to prevent optical performance degradation due to coating delamination.
Other PET deep processing applications: For decorative films and building material films, improves the receptivity of PET substrates to subsequent decorative layers and adhesive backing layers, elevating overall product quality.
V. Product Packaging:
25KG/bag. Store sealed in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and open flames. Recommended storage temperature: 5°C - 35°C.
