Description

Fatty Acids, Castor-Oil, Polymd., Distn. Residues, Polymers With 1,3-Butanediol And Propylene Glycol CAS NO 70955-21-4 is a specialized polymeric ester derived from castor oil fatty acids, offering a unique combination of hydrophobicity, flexibility, and adhesion. This product matters for formulators seeking high-performance, bio-based raw materials to enhance the durability and functionality of their end products. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of plasticizers and lubricant additives.

Application

• Coatings & Inks: Acts as a polymeric plasticizer and resin modifier in alkyd paints, polyurethane coatings, and printing inks to improve flexibility, gloss, and adhesion to various substrates.
• Adhesives & Sealants: Used as a tackifier and flexibilizing agent in hot-melt, pressure-sensitive, and structural adhesives, as well as in sealants for construction and automotive applications.
• Polymer Modification: Serves as a reactive intermediate or compatibilizer in the synthesis and modification of polyesters, polyurethanes, and other polymers to tailor physical properties.
• Lubricants & Greases: Functions as a thickening agent and performance additive in synthetic and bio-based lubricants and greases, contributing to thermal stability and water resistance.
• Plasticizers: Employed as a secondary plasticizer or stabilizer in PVC and other polymer compounds to enhance low-temperature performance and reduce migration.
• Elastomers: Incorporated into rubber formulations to improve processing characteristics, tensile strength, and resistance to weathering and oils.

Quality Control

Our production of Fatty Acids, Castor-Oil, Polymd., Distn. Residues, Polymers With 1,3-Butanediol And Propylene Glycol adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistency in key parameters such as acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen blanket) to preserve product integrity. Keep away from strong oxidizers, heat, and ignition sources.
