Description

Propylene Glycol-Dipropylene Glycol-Neopentyl Glycol-4,4'-(1-Methylethylidiene)Bis-Cyclohexanol-Maleic Anhydride-Copolymer is a high-performance, multi-component polyester polyol copolymer designed for demanding industrial applications. This specialized resin offers a unique balance of properties derived from its complex monomer composition, including flexibility, chemical resistance, and controlled reactivity. It is primarily utilized by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Coatings Resin: Serves as a key polyol component in the formulation of advanced polyurethane and alkyd coatings, providing excellent weatherability, gloss retention, and chemical resistance for automotive, industrial, and marine finishes.
• Adhesive & Sealant Formulations: Used to develop flexible, durable adhesives and sealants with strong bonding characteristics and good resistance to environmental stress cracking.
• Elastomer Production: Acts as a building block in the synthesis of polyurethane elastomers, contributing to tailored hardness, tensile strength, and rebound resilience for industrial parts and components.
• Composite Materials: Employed in the production of fiber-reinforced plastics and composite materials, where it contributes to matrix toughness and interfacial adhesion.
• Industrial Ink Binders: Functions as a reactive resin in specialty printing inks, offering good pigment wetting and film-forming properties.

Quality Control

Our Propylene Glycol-Dipropylene Glycol-Neopentyl Glycol-4,4'-(1-Methylethylidiene)Bis-Cyclohexanol-Maleic Anhydride-Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) documenting these key specifications are provided to guarantee the material meets the precise requirements for your formulation. We support compliance with relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
