Description

Soybean Oil, Polymer With Pentaerythritol, Phthalic Anhydride And 2,2,4-Trimethyl-1,3-Pentanediol CAS NO 68555-02-2 is a specialized alkyd resin derived from renewable soybean oil, modified with pentaerythritol, phthalic anhydride, and a branched diol. This polymer is engineered to provide excellent film-forming properties, flexibility, and adhesion, making it a crucial component in high-performance coating formulations. It is primarily sought after by manufacturers in the paints, coatings, and inks industries who require sustainable raw materials with enhanced durability and drying characteristics.

Application

• Industrial and Architectural Coatings: As a primary resin binder in solvent-borne and high-solids alkyd paints, offering good gloss and weather resistance.
• Protective Marine and Maintenance Paints: Provides a tough, flexible film that adheres well to metal substrates, offering corrosion protection.
• Printing Inks: Used in specialty ink formulations requiring rapid setting and good pigment wetting properties.
• Wood Finishes and Varnishes: Imparts clarity, depth of color, and protection for furniture and flooring applications.
• Adhesives and Sealants: Acts as a tackifier and film-forming agent, contributing to bond strength and flexibility.
• Primers and Undercoats: Enhances surface adhesion and provides a uniform base for topcoats.

Quality Control

Our production of this alkyd resin adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. A Certificate of Analysis (COA) is provided with each shipment, detailing these specifications. We operate under a quality management system and can support compliance with relevant industry standards for coatings and polymers.

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 sources and open flame. Due to its nature, the product should be stored under conditions that minimize oxidation; keep containers tightly sealed when not in use.
