Features Of AAAA-5366 Hydroxy Acrylic Resin

  1. High hydroxyl functionality (OH value: 85–95 mg KOH/g) for excellent crosslinking efficiency with isocyanates and melamine resins.

  2. Outstanding weather resistance and UV stability, maintaining gloss and color retention in demanding outdoor environments.

  3. Low viscosity (4,000–6,000 cP at 25°C) enabling easy handling, solvent reduction, and high-solids formulation flexibility.

  4. Excellent compatibility with common acrylics, polyesters, and curing agents used in industrial coatings systems.

  5. Consistent batch-to-batch reproducibility ensured through strict GMP-aligned manufacturing controls.

Typical Applications Of AAAA-5366 Hydroxy Acrylic Resin

  1. Automotive OEM and refinish topcoats requiring high gloss, chip resistance, and durability.

  2. Industrial maintenance coatings for metal substrates in infrastructure, agricultural, and construction equipment.

  3. General-purpose coil coatings for pre-painted steel and aluminum applications.

  4. High-performance plastic coatings for automotive interior and exterior trim components.

  5. Architectural metal façade coatings subject to stringent AAMA 2605 performance requirements.
