Description

Fatty Acids, Linseed-Oil, Polymers With Glycerol, Phthalic Anhydride And Rosin is a complex, modified alkyd resin derived from natural and synthetic raw materials, designed to impart specific performance characteristics in industrial formulations. This compound matters for its ability to enhance film formation, adhesion, and durability in coatings and inks. It is primarily needed by manufacturers in the paint, varnish, printing ink, and adhesive industries seeking bio-based modifiers and performance resins.

Application

• Industrial Coatings: As a modifying resin in air-drying alkyd paints and varnishes to improve drying time, gloss, and flexibility.
• Printing Inks: Used in lithographic and letterpress ink formulations to enhance pigment wetting, flow, and final film properties.
• Adhesives & Sealants: Acts as a tackifier and rheology modifier in solvent-based adhesive systems.
• Wood Finishes: A key component in wood stains and clear finishes, providing deep penetration and a protective film.
• Metal Primers: Contributes to adhesion promotion and corrosion resistance in primer coatings for metal substrates.
• Artists' Materials: Found in high-quality oil paints and mediums to modify consistency and drying behavior.

Quality Control

Our Fatty Acids, Linseed-Oil, Polymers With Glycerol, Phthalic Anhydride And Rosin is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as acid value, viscosity, color, and solids content to ensure batch-to-batch consistency and performance in your application. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C. Keep away from strong acids and oxidizing agents. Due to its polymeric nature and components, prolonged storage at elevated temperatures should be avoided to prevent changes in viscosity and other properties.
