KDD KDD731 Acrylic Resin

KDD 731 is an adhesion-enhanced resin modified by special monomer polymerization from KDD Chemicals' PET-specific modified thermoplastic acrylic resin series, designed for coating of PET plastic and flexible substrates. This water-white transparent viscous liquid resin with environmentally friendly dimethyl carbonate as solvent has a solid content of 50%, excellent adhesion to PET substrates, forming film with good anti-blocking property and firm interlayer bonding

Features Of KDD KDD731 Acrylic Resin

  1. PET-specific adhesion - Customized for PET plastic substrates, with strong adhesion, solving the industry pain point of difficult PET coating.

  2. Excellent anti-blocking property - Outstanding anti-blocking after film formation, avoiding coating adhesion and ensuring stability of end product storage and transportation.

  3. Good interlayer compatibility - Excellent interlayer adhesion, can be used as intermediate layer of composite coating to improve overall bonding strength of coating.

  4. Environmentally friendly solvent system - Using dimethyl carbonate solvent, meeting the trend of environmental coating, safer and more compliant to use.

Typical Applications Of KDD KDD731 Acrylic Resin

  1. PET film coatings: Single-component coatings for PET packaging films and electronic films, improving surface protection and printing adaptability.

  2. Flexible substrate coating: Single-component coatings for flexible plastics, leather and other flexible substrates, adapting to flexible deformation of substrates without brittleness.

  3. UV/PU primer matching: Used as primer for UV or PU coatings, improving adhesion between topcoat and substrate, optimizing overall coating performance.

  4. Composite packaging coatings: Coatings for food and daily chemical PET composite packaging, anti-blocking and environmentally friendly, ensuring packaging safety.
