Features Of AAAA-5387 Hydroxy Acrylic Resin

  1. High hydroxyl functionality (OH# 120–140 mg KOH/g) for excellent crosslinking efficiency with melamine and polyisocyanate curing agents.

  2. Superior weather resistance and UV stability, maintaining gloss and color retention in demanding outdoor applications.

  3. Low viscosity (4,000–6,000 cP at 25°C) enabling high-solids formulation with reduced VOC emissions.

  4. Excellent compatibility with common acrylics, alkyds, and polyester resins for hybrid coating systems.

  5. Consistent batch-to-batch reproducibility supported by strict in-process QC and GMP-aligned manufacturing.

Typical Applications Of AAAA-5387 Hydroxy Acrylic Resin

  1. Automotive OEM clearcoats and basecoats requiring high film integrity and chip resistance.

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

  3. High-performance coil coatings for pre-painted steel used in building façades and appliances.

  4. Powder coating hybrids where hydroxyl functionality enables low-cure-temperature crosslinking.

  5. UV-curable hybrid topcoats leveraging synergistic reactivity with acrylate-functional co-resins.
