Description

Soybean Oil, Polymer With Glycerol, Pentaerythritol, Phthalic Anhydride And Styrene is a specialized alkyd resin, a synthetic polymer derived from renewable and petrochemical feedstocks. This versatile compound is engineered to provide a balanced profile of film-forming properties, flexibility, and adhesion. It is a critical raw material for formulators in the coatings and inks industries seeking to enhance product performance with a partial bio-based component. The CAS number for this substance is 68390-06-7.

Application

This modified alkyd resin is a foundational component in various industrial formulations, prized for its film integrity and compatibility.

• Industrial and Architectural Coatings: Used as a primary resin or modifier in air-drying and baking enamels, primers, and varnishes to improve gloss, durability, and drying time.
• Printing Inks: Serves as a vehicle resin for offset, letterpress, and screen inks, contributing to pigment wetting, gloss, and rub resistance.
• Adhesives and Sealants: Imparts tack, flexibility, and adhesion in certain adhesive formulations and mastic products.
• Wood Finishes: A key ingredient in clear wood stains, lacquers, and furniture coatings, enhancing grain definition and protective qualities.
• Metal Coatings: Utilized in corrosion-resistant primers and finishes for metal substrates, often modified for specific curing profiles.
• Specialty Resins: Acts as a polymeric plasticizer or modifier in other resin systems to tailor flexibility and chemical resistance.

Quality Control

Our production of this alkyd resin adheres to strict batch-to-batch consistency protocols. Key parameters such as acid value, viscosity, solids content, and color are rigorously monitored against internal specifications. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to ensure traceability and quality assurance for your formulation process.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Due to its chemical nature, it should be stored separately from strong acids and oxidizing agents. Under recommended conditions, the product is typically stable for 24 months from the date of manufacture.
