Description

Linseed Oil, Polymer With Benzoic Acid, Glycerol And Phthalic Anhydride is a specialized alkyd resin, a synthetic polymer derived from the polycondensation of linseed oil fatty acids with benzoic acid, glycerol, and phthalic anhydride. This compound is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance, making it a critical component in high-performance coating formulations. It is primarily utilized by manufacturers in the paints, coatings, and industrial resins sectors seeking to enhance the durability and application properties of their products.

Application

• Primary binder in high-quality industrial and architectural alkyd paints and enamels.
• Key resin component in protective coatings for metal, wood, and concrete substrates.
• Formulation of printing inks requiring excellent gloss and rub resistance.
• Manufacture of adhesives and sealants where flexibility and adhesion are paramount.
• Production of corrosion-resistant primers for automotive and marine applications.
• Base for specialty industrial maintenance coatings.

Quality Control

Our production of Linseed Oil Alkyd Resin adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, viscosity, solids content, and color. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its nature, the product should be kept under an inert atmosphere if long-term storage is required to prevent skinning or gelation. Ideal storage temperature is between 15°C and 25°C.
