Description

Maleic Anhydride, Polymer With Phthalic Anhydride, Dicyclopentadiene, Ethylene Glycol And Diethylene Glycol CAS NO 98101-29-2 is a specialized unsaturated polyester resin intermediate. This compound is engineered to deliver enhanced reactivity and tailored polymer properties, making it a critical raw material for high-performance thermoset applications. It is primarily needed by manufacturers in the composites, coatings, and automotive industries seeking to produce durable, chemically resistant end-products.

Application

• Unsaturated Polyester Resins (UPR): Primary component for the production of fiberglass-reinforced plastics (FRP) used in marine hulls, automotive body panels, and storage tanks.
• Gel Coats & Surface Coatings: Provides excellent surface finish, weatherability, and chemical resistance for bathtubs, swimming pools, and industrial equipment.
• Corrosion-Resistant Linings: Formulated into coatings and linings for pipes, ducts, and chemical processing vessels.
• Electrical Laminates: Used in the manufacture of printed circuit boards (PCBs) and electrical insulation components.
• Automotive Parts: Key resin for sheet molding compound (SMC) and bulk molding compound (BMC) used in lightweight structural components.
• Artificial Stone & Solid Surfaces: Binder material for engineered quartz countertops and sanitaryware.

Quality Control

Our production of this polyester intermediate adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, viscosity, and non-volatile content. Certificates of Analysis (COA) documenting these specifications are available for every shipment to ensure the material meets your formulation requirements.

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). This material is hygroscopic (moisture-sensitive); containers must be kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect reactivity and properties.
