Description

Fatty Acids, C16-18 And C18-Unsatd., Branched And Linear, Polymers With p-tert-Butylbenzoic Acid, Peanut-Oil Fatty Acids, Pentaerythritol And Phthalic Anhydride CAS NO 129783-13-7 is a specialized polymeric resin derived from a complex formulation of fatty acids and polybasic acids. This product matters as a high-performance, versatile intermediate designed to impart specific chemical resistance, adhesion, and flexibility properties to final formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• Alkyd Resin Modifier: Used to improve flexibility, drying time, and weather resistance in surface coatings and paints.
• Adhesive & Sealant Formulation: Acts as a tackifier and plasticizer to enhance adhesion strength and elasticity.
• Polymer Additive: Incorporated into various polymer systems to modify rheological properties and chemical resistance.
• Industrial Coating Binder: Serves as a key component in corrosion-resistant and protective coatings for metal and concrete.
• Printing Ink Resin: Provides gloss, adhesion, and rub resistance in specialty ink formulations.
• Plasticizer & Stabilizer: Used in PVC and other plastic compounds to improve processability and end-product performance.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production follows strict in-process controls, and each batch is characterized for key parameters such as acid value, viscosity, and color. Certificates of Analysis (COA) documenting these 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, well-ventilated area at room temperature (15-25°C). This material is sensitive to strong acids/organic solvents and is easily oxidized; it is recommended to store under an inert atmosphere such as nitrogen for long-term preservation to maintain optimal quality. Keep away from heat and ignition sources.
