Description

Fatty Acids, Linseed-Oil, Polymers With Glycerol, Linseed Oil And Phthalic Anhydride is a specialized alkyd resin intermediate, a polymer derived from the polycondensation of linseed oil fatty acids, glycerol, and phthalic anhydride. This compound is valued for its ability to impart excellent flexibility, adhesion, and durability to surface coatings. It is primarily needed by manufacturers in the paints, coatings, and printing inks industries seeking to formulate high-performance, air-drying products.

Application

• Primary binder/resin component in air-drying alkyd paints and varnishes.
• Modifying resin to enhance flexibility and adhesion in industrial and architectural coatings.
• Key ingredient in the formulation of high-gloss printing inks.
• Used as a plasticizer and film-forming agent in protective wood finishes.
• Intermediate for manufacturing corrosion-resistant metal primers.
• Component in specialty artists' paints and mediums.
• Base for flexible maintenance coatings for machinery and equipment.

Quality Control

Our alkyd resin intermediates are produced under strict process controls to ensure batch-to-batch consistency. Quality is verified through parameters such as acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting these specifications are available upon request to support 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 easily oxidized; containers should be kept tightly sealed when not in use to minimize contact with air.
