Description

Soybean Oil, Polymer With Glycerol, Maleic Anhydride, Phthalic Anhydride And Vinyltoluene is a specialized alkyd-type resin derived from modified soybean oil. This compound matters for its ability to impart flexibility, adhesion, and durability in coatings and composite materials. It is primarily needed by manufacturers in the paints & coatings, adhesives, and plastics industries seeking bio-based or modified polymer components.

Application

• Industrial Coatings Binder: Used as a film-forming agent in air-drying and baking enamels for metal and wood substrates.
• Adhesive Formulation: Serves as a tackifying and flexibilizing resin in pressure-sensitive and structural adhesives.
• Plastic & Composite Modifier: Incorporated as a plasticizer or impact modifier in various polymer blends and composites.
• Printing Ink Vehicle: Acts as a resinous component in specialty printing inks, contributing to gloss and substrate adhesion.
• Sealant & Caulk Formulation: Provides elasticity and weather resistance in construction and automotive sealants.
• Foundry Core Binder: Utilized in sand-casting processes as a part of binder systems for mold and core making.

Quality Control

Our Soybean Oil Polymer is produced under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, solids content, and color to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air, heat, or light should be avoided to maintain product integrity.
