Adhesion-enhancing resin (EVA substrate) achieves molecular compatibility and chemical bonding with the EVA substrate by introducing polar vinyl acetate segments and crosslinking active groups into its molecular chains. This effectively resolves issues of poor adhesion and easy peeling of coatings and adhesives on EVA substrates while enhancing the moisture resistance and weather resistance of EVA products.

III. Product Characteristics:
Deep Penetration and Anchoring: Its low viscosity enables effective penetration into the microporous structure of EVA foam, forming a robust physical anchorage that prevents interfacial failure.
Exceptional Flexibility: The cured coating exhibits high flexibility, deforming without cracking when the EVA substrate bends or compresses, perfectly matching the dynamic usage environment of EVA products.
Broad-Spectrum Bonding Enhancement: Significantly boosts adhesion strength between EVA and various systems including epoxy resins, polyurethanes (PU), acrylic adhesives, and rubber-based adhesives.
Superior Fatigue Resistance: Excellent resistance to repeated flexing and vibration, suitable for products requiring long-term dynamic use such as footwear materials and sports equipment.
Easy to Use: Can be applied as a primer or directly incorporated into adhesives as an additive. Highly adaptable with minimal disruption to existing production processes.
IV. Product Applications:
Footwear Manufacturing: Bonding EVA midsoles, insoles to uppers, and outsoles (e.g., rubber, TPU); enhancing adhesion for knit upper coatings.
Sports Equipment: Laminating and printing EVA yoga mats, floor mats, surfboard skins, and athletic protective gear.
Packaging Industry: Bonding and securing EVA foam packaging liners to other materials.
Automotive Interiors: Bonding EVA soundproofing mats, carpet backing, and vehicle steel panels.
Electronics Industry: Bonding EVA-based sealing/cushioning materials to plastic or metal enclosures.
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.
