Description

Fatty Acids,Soya,Polymers With p-tert-Butylbenzoic Acid,Pentaerythritol And Phthalic Anhydride CAS NO 66071-26-9 is a specialized polymeric resin derived from modified soybean oil fatty acids, pentaerythritol, phthalic anhydride, and p-tert-butylbenzoic acid. This engineered polymer is valued for its excellent film-forming properties, chemical resistance, and versatility as a binder or modifying agent. It serves as a critical raw material for formulators in the coatings, adhesives, and ink industries seeking sustainable and high-performance resin solutions.

Application

• Alkyd Resin Modifier: Used to enhance the drying time, flexibility, and durability of alkyd-based surface coatings and paints.
• Industrial Coatings: Acts as a key binder in protective coatings for metal, wood, and concrete, offering good adhesion and corrosion resistance.
• Printing Inks: Employed in the formulation of specialty inks, contributing to gloss, rub resistance, and pigment wetting.
• Adhesives & Sealants: Functions as a tackifying or reinforcing resin in adhesive compositions, improving bond strength and thermal stability.
• Polymer Plasticizer: Serves as a secondary plasticizer or compatibilizer in various polymer systems to improve processability and mechanical properties.
• Marine & Protective Coatings: Suitable for high-performance coatings that require resistance to water, chemicals, and weathering.

Quality Control

Our production of this polymeric resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. Certificates of Analysis (COA) documenting all relevant 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, and well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. Ensure containers are kept tightly sealed when not in use to prevent skin formation or changes in viscosity.
