KDD KDD728 Acrylic Resin

KDD 728 is a functional resin from KDD Chemicals' flexible multi-substrate adhesive modified hydroxyl acrylic resin series, designed for coating of flexible substrates and hard-to-adhere composite materials. This transparent liquid resin with toluene/PMA mixed solvent system has a solid content of 55%, excellent adhesion to TPU, TPR soft rubber, nylon+glass fiber and other substrates

Features Of KDD KDD728 Acrylic Resin

  1. Flexible substrate-specific adhesion - Customized for TPU, TPR and other soft rubber substrates, with strong adhesion, adapting to flexible deformation of substrates without peeling.

  2. Hard-to-adhere material compatibility - Excellent adhesion to nylon+glass fiber, carbon fiber and other composite materials, solving the industry pain point of difficult coating.

  3. Balanced flexibility and high gloss - Outstanding film flexibility, combined with high gloss performance, excellent both in decoration and service performance.

  4. Full-scene universal characteristics - Universal for silver/color paints and primer-topcoats, reducing resin inventory and formula switching costs.

Typical Applications Of KDD KDD728 Acrylic Resin

  1. Soft rubber product coating: Coating for TPU/TPR soft rubber toys and sports equipment, adapting to flexible deformation, with firm coating without cracking.

  2. Nylon+glass fiber products: Coating for automotive nylon+glass fiber components and electronic casings, solving the problem of poor adhesion and ensuring service stability.

  3. Carbon fiber product protection: Coating for carbon fiber sports equipment and industrial components, enhancing surface protection and appearance texture.

  4. Leather decorative coating: Topcoat for high-grade leather products, improving surface gloss and wear resistance, maintaining soft leather touch.
