Description

Soybean Oil, Polymer With p-tert-Butylbenzoic Acid, Pentaerythritol And Phthalic Anhydride is a specialized alkyd resin polymer derived from modified soybean oil. This compound is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance for high-performance coating systems. It is a critical raw material for formulators in the industrial coatings and inks sectors seeking sustainable, bio-based alternatives. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding manufacturing processes.

Application

• Industrial and Protective Coatings: As a primary resin or modifier in metal primers, machinery enamels, and corrosion-resistant finishes.
• Printing Inks: Used in the formulation of specialty inks, including overprint varnishes and packaging inks, for enhanced gloss and rub resistance.
• Adhesives and Sealants: Acts as a tackifier and flexibilizing agent in solvent-based adhesive systems.
• Wood Finishes: Imparts durability and clarity in varnishes and stains for furniture and flooring applications.
• Plastic Coatings: Provides adhesion promotion and surface protection for coated plastic substrates.
• Marine Coatings: Contributes to the formulation of anti-fouling and water-resistant paint systems.

Quality Control

Our production of Soybean Oil Polymer adheres to stringent quality management protocols. Every batch is characterized for critical parameters including acid value, viscosity, color, and solids content to ensure it meets precise performance specifications. Certificates of Analysis (COA) documenting these results are available upon request. We are committed to supplying material that supports our customers' needs for REACH compliance and consistent integration into global supply chains.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and organic solvents. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to prevent skinning or changes in viscosity.
