Description

Fatty Acids, C18-Unsatd., Dimers, Polymers With Bisphenol A, C18-Unsatd. Fatty Acid Trimers And Epichlorohydrin is a specialized polymeric resin derived from unsaturated C18 fatty acid dimers and trimers, bisphenol A, and epichlorohydrin. This chemistry provides a unique combination of flexibility, adhesion, and chemical resistance, making it a valuable intermediate for high-performance formulations. It is primarily sought by manufacturers in the coatings, adhesives, and advanced polymer industries seeking to enhance the durability and functional properties of their end products.

Application

• High-Performance Coatings Resin: Used as a building block for epoxy-modified alkyds and other specialty coating resins, offering excellent weatherability, gloss, and adhesion to metal substrates.
• Industrial Adhesives and Sealants: Serves as a key polymeric component in structural adhesives and sealants, contributing to toughness, flexibility, and bond strength.
• Composite Materials: Acts as a modifier or cross-linking agent in fiber-reinforced plastics and composite matrices to improve impact resistance and interfacial adhesion.
• Printing Inks: Utilized in the formulation of specialty inks, such as overprint varnishes and metal-decorating inks, to provide scuff resistance and good flow properties.
• Can and Coil Coatings: An important intermediate for coatings applied to food containers, beverage cans, and architectural coil, where flexibility and corrosion resistance are critical.
• Electrical Insulating Varnishes: Incorporated into varnishes for motors and transformers due to its good dielectric properties and thermal stability.

Quality Control

Our production of this polymeric resin adheres to strict quality management systems. Each batch is characterized for critical parameters including epoxy equivalent weight (EEW), viscosity, acid value, and color to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request, providing full traceability and compliance data for 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 product is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent moisture uptake, which can affect reactivity and viscosity. It is also easily oxidized; containers should be kept tightly sealed when not in use to minimize exposure to air.
