Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Bisphenol A, Epichlorohydrin And Tall-Oil Fatty Acids CAS NO 68038-09-5 is a specialized polymeric resin derived from the reaction of tall oil fatty acid dimers, bisphenol A, and epichlorohydrin. This product is engineered to provide exceptional chemical resistance, adhesion, and flexibility, making it a critical component in high-performance industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking durable and reliable polymeric backbones.

Application

• High-Performance Industrial Coatings: Used as a resinous backbone in epoxy-modified alkyds and other coating systems requiring superior chemical and corrosion resistance.
• Structural Adhesives & Sealants: Imparts flexibility and strong adhesion to metals, plastics, and composites in demanding bonding applications.
• Elastomer Modification: Acts as a flexibilizer and compatibilizer in rubber and elastomeric compounds to enhance durability and processing.
• Marine & Protective Coatings: A key ingredient in formulations designed to withstand harsh environmental conditions, including saltwater and UV exposure.
• Can & Coil Coatings: Provides the necessary film properties for coatings applied to metal packaging and architectural cladding.
• Electrical Insulating Varnishes: Used in resin systems for insulating wires and electrical components due to its thermal stability and dielectric properties.
