Description

9,12-Octadecadienoic acid (9Z,12Z)-, dimer, polymer with 2,2-bis(hydroxymethyl)-1,3-propanediol, 1,3-diisocyanatomethylbenzene and 2-propenoic acid, Bu alc.-modified is a specialized, high-performance polymeric resin derived from linoleic acid dimer. This compound is engineered to deliver exceptional durability, flexibility, and adhesion, making it a critical component in advanced coating formulations. It is primarily sought after by manufacturers in the industrial coatings, adhesives, and specialty polymers sectors for its ability to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a key resin in high-performance coatings for metal, wood, and plastic substrates, providing excellent weather resistance and mechanical strength.
• Adhesives and Sealants: Serves as a primary binder in structural and flexible adhesive formulations, offering strong bonding and cohesive properties.
• UV-Curable Systems: Acts as a reactive oligomer in UV-curable inks, coatings, and 3D printing resins, enabling fast curing and high crosslink density.
• Automotive Finishes: Incorporated into automotive clear coats and primer surfaces for enhanced gloss retention and scratch resistance.
• Flexible Packaging Inks: Utilized in printing inks for flexible packaging due to its good adhesion to various films and low odor characteristics.
• Marine and Anti-Corrosive Coatings: Formulated into coatings that protect against saltwater, humidity, and chemical exposure in harsh marine environments.

Quality Control

Our production of this advanced polymeric resin adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. While specific grades can be tailored, our standard quality commitment includes monitoring of key parameters such as viscosity, acid value, and degree of functionalization. Certificates of Analysis (COA) documenting purity, physical properties, and performance characteristics 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, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product performance.
