Description

Soybean Oil, Polymer With Isophthalic Acid And Pentaerythritol CAS NO 66071-86-1 is a modified alkyd resin derived from renewable soybean oil, offering a sustainable and versatile polymeric backbone. This product matters for formulators seeking to enhance the flexibility, adhesion, and durability of coatings and inks while incorporating bio-based content. It is primarily needed by manufacturers in the paints, coatings, printing inks, and adhesive industries for producing high-performance, environmentally conscious formulations.

Application

• Industrial and Architectural Coatings: As a resin modifier in air-drying and baking enamels to improve film flexibility and gloss retention.
• Printing Inks: Used in the formulation of lithographic, flexographic, and gravure inks to enhance pigment wetting and substrate adhesion.
• Adhesives and Sealants: Acts as a tackifier and plasticizer, improving the bond strength and elasticity of pressure-sensitive and structural adhesives.
• Wood Finishes: Imparts excellent penetration and durability in varnishes and stains for furniture and flooring.
• Metal Primers: Provides good corrosion resistance and adhesion to metal substrates in protective coating systems.
• Plastic Coatings: Enhances the compatibility and finish of coatings applied to various plastic materials.

Quality Control

Our production of Soybean Oil, Polymer With Isophthalic Acid And Pentaerythritol adheres to stringent quality management protocols. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, color, and solids content to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory needs.

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/59-77°F). Keep away from strong acids, organic solvents, and sources of heat or ignition. Due to its nature, prolonged exposure to air should be minimized to prevent skinning or oxidative thickening.
