Description

Maleic Anhydride, Polymer With Isophthalic Acid, 1,2-Propane Diol, Oxydipropanol And 2,2-Dimethyl-1,3-Propanediol CAS NO 60305-10-4 is a specialized unsaturated polyester resin intermediate, engineered to deliver a precise balance of reactivity, mechanical strength, and chemical resistance. This high-performance polymer is critical for formulating advanced thermoset composites and coatings with superior durability. It is primarily sought by manufacturers in the automotive, marine, construction, and industrial coating sectors for producing high-grade gel coats, laminates, and corrosion-resistant linings.

Application

• High-Performance Gel Coats & Surface Finishes: Provides excellent surface smoothness, water resistance, and gloss retention for boat hulls, sanitary ware, and automotive body panels.
• Corrosion-Resistant Tanks & Pipes: Used in the fabrication of chemical storage tanks, process vessels, and piping linings for aggressive environments.
• Marine & Transportation Composites: A key resin component for manufacturing lightweight, strong laminates used in boat decks, truck fairings, and rail components.
• Industrial Protective Coatings: Formulated into durable coatings for flooring, structural steel, and concrete in demanding industrial settings.
• Pultrusion & Compression Molding: Serves as a matrix resin for producing continuous fiber-reinforced profiles, electrical insulators, and engineered composite parts.
• Artificial Stone & Solid Surface Materials: Imparts hardness, stain resistance, and thermal stability to engineered quartz and acrylic-solid surfaces.

Quality Control

Our production of this unsaturated polyester resin adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, gel time, and styrene content to ensure optimal curing performance and final product properties. Certificates of Analysis (COA) detailing specific batch data are available upon request, supporting compliance with relevant industry and customer-specific specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources, sparks, and open flame. Containers must be kept tightly sealed when not in use to prevent moisture absorption and maintain reactivity.
