Description

9,12-Octadecadienoic Acid (Z,Z)-, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol, 1,3-Isobenzofurandione And 1,2,3-Propanetriol, Benzoate is a specialized polymeric resin derived from linoleic acid, a drying oil fatty acid, and key polyol and acid components. This engineered polymer is valued for its ability to form durable, flexible, and chemically resistant films and coatings. It is primarily required by manufacturers in the paints, coatings, inks, and adhesive industries seeking bio-based or modified alkyd resin properties.

Application

• Industrial Coatings: As a film-forming agent in air-drying or baking enamels for metal and wood substrates.
• Printing Inks: Used in the formulation of offset, lithographic, and specialty inks to enhance gloss, adhesion, and drying properties.
• Adhesives & Sealants: Acts as a tackifying and flexibilizing resin component in structural and pressure-sensitive adhesive systems.
• Polymer Modification: Serves as a reactive intermediate or additive to modify the flexibility and weathering resistance of other polymers.
• Protective Coatings: For corrosion-resistant primers and finishes in automotive, marine, and industrial maintenance applications.
