High-Purity Neopentyl Glycol (NPG) – Premium Polyester & Alkyd Resin Modifier for High-Performance Coatings

We are a leading global supplier of Neopentyl Glycol (NPG), a versatile saturated diol renowned for its exceptional resistance to hydrolysis, UV light, and chemicals. As a key raw material in high-performance polyester and alkyd resins, NPG significantly enhances the durability, weatherability, and gloss retention of industrial and decorative coatings.

KEY APPLICATIONS FOR BULK BUYERS:

  • High-Performance Polyester Resins: Essential monomer in saturated polyester resins for powder coatings, coil coatings, automotive topcoats, and can coatings, providing outstanding weather resistance and flexibility.

  • Alkyd Resins: Modifies alkyd resins for industrial and architectural paints to improve color retention, durability, and chemical resistance.

  • Polyurethane (PU) Applications: Used as a chain extender or polyol component in PU coatings, elastomers, and adhesives to enhance mechanical properties and hydrolytic stability.

  • Synthetic Lubricants: Base component for neopentyl polyol esters, which are high-performance synthetic lubricants and compressor oils with excellent thermal stability.

  • Plasticizers & Stabilizers: Intermediate in the production of specialty plasticizers and heat stabilizers for PVC and other polymers.

WHOLESALE SUPPLIER ADVANTAGES:

  • High Purity & Quality: Typically ≥ 99% purity with low moisture and acidity for consistent polymerization performance.

  • Bulk & Custom Supply: Available in 25 kg bags, 500 kg big bags, and bulk shipments (pellets/flakes) tailored to industrial-scale production.

  • Competitive Bulk Pricing: Cost-effective supply for resin manufacturers, coating formulators, chemical processors, and distributors with volume-based pricing.

  • Global Logistics & Compliance: Reliable international shipping supported by full SDS, COA, and regulatory documentation.

  • Technical & Formulation Expertise: In-depth support for resin synthesis, coating formulation, and performance optimization.
