Description

9,11-Octadecadienoic acid, polymer with (chloromethyl)oxirane, ethenylbenzene, 4,4'-(1-methylethylidene)bis[phenol], 2-methyl-2-propenoic acid and (Z,Z)-9,12-octadecadienoic acid is a specialized, high-performance polymeric resin designed for advanced coating and adhesive formulations. This multi-component copolymer offers a unique balance of properties derived from its fatty acid, epoxy, styrene, bisphenol-A, and acrylic constituents, making it a critical raw material for demanding industrial applications. It is essential for manufacturers seeking to enhance the durability, chemical resistance, and adhesion characteristics of their final products.

Application

• High-Performance Industrial Coatings: Used as a binder or resin component in protective coatings for metal, concrete, and other substrates requiring excellent corrosion and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a key polymeric backbone in structural adhesives, laminating adhesives, and high-strength sealants, providing robust bonding and flexibility.
• Can & Coil Coatings: Formulated into coatings for food and beverage cans, industrial coil, and pre-coated metal, offering superior adhesion and barrier properties.
• Automotive & Transportation Finishes: Incorporated into primer, basecoat, or clearcoat systems to improve durability, gloss retention, and resistance to fuels and solvents.
• Marine & Protective Coatings: Ideal for harsh environments, used in marine paints, offshore platform coatings, and heavy-duty industrial maintenance paints.
• Electrical Insulating Varnishes: Applied in the formulation of wire enamels and insulating coatings for electrical components due to its thermal stability and dielectric properties.
• Printing Inks: Utilized as a resin in specialty printing inks that require fast drying, high gloss, and resistance to abrasion and chemicals.

Quality Control

Our production of this advanced polymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. Quality is monitored against key parameters including viscosity, acid value, epoxy equivalent weight, and solid content. Certificates of Analysis (COA) detailing these specifications are available for every batch upon request, supporting your quality assurance and regulatory compliance needs.

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 heat sources and open flames. Ensure containers are kept tightly sealed when not in use to prevent skinning or changes in viscosity.
