Description

Maleic Anhydride, Polymer With Propylene Glycol, Ethylene Glycol, 3-Oxa-1,5-Pentanediol And 3A,4,7,7A-Tetrahydro-1,3-Dioxo-2-Oxaindan is a specialized polymeric resin derived from maleic anhydride and a blend of diols, including a tetrahydro-oxaindan derivative. This unique copolymer structure provides excellent reactivity and film-forming properties, making it a valuable intermediate for high-performance industrial coatings and adhesives. It is primarily sought by manufacturers in the paints, coatings, and specialty polymer industries for formulating products that require enhanced durability, chemical resistance, and cross-linking efficiency.

Application

• Industrial and Protective Coatings: As a key resin component in alkyds and polyesters for metal primers, automotive finishes, and corrosion-resistant industrial paints.
• Adhesives and Sealants: Used to formulate high-strength structural adhesives and flexible sealants with improved adhesion to various substrates.
• Unsaturated Polyester Resins (UPR): Serves as a reactive modifier in UPR systems for fiberglass-reinforced plastics (FRP), gel coats, and cultured marble.
• Printing Inks: Imparts hardness, gloss, and drying properties in overprint varnishes and specialty printing ink formulations.
• Cross-linking Agent: Functions as a co-monomer or cross-linker in thermosetting polymer systems to enhance thermal and mechanical properties.
• Water-Reducible Resins: A precursor for developing more environmentally friendly, low-VOC (Volatile Organic Compound) coating systems.

Quality Control

Our production of this polymeric resin adheres to strict batch-to-batch consistency protocols to ensure reliable performance in downstream formulations. Quality is monitored through key parameters including acid value, viscosity, solids content, and color. Certificates of Analysis (COA) detailing the specific specifications for each lot are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flames. Under these conditions, the product is typically stable for 24 months from the date of manufacture. Prolonged exposure to high humidity should be avoided.
