Description

Tall-Linseed Oil/Phthalic Anhydride/Glycerol Resin is a specialized alkyd resin produced by the condensation polymerization of tall oil fatty acids, linseed oil, phthalic anhydride, and glycerol. This compound is valued for its excellent film-forming properties, durability, and versatility as a binder in surface coating formulations. It is a critical raw material for manufacturers in the protective coatings, industrial paints, and printing inks industries seeking high-performance, cost-effective resin solutions.

Application

• Industrial and Protective Coatings: As a primary binder in air-drying and heat-cured paints for metal structures, machinery, and agricultural equipment.
• Architectural Paints: Used in the formulation of exterior house paints and primers, offering good weather resistance and adhesion.
• Printing Inks: Serves as a resin vehicle in offset and lithographic printing inks, providing gloss and rub resistance.
• Wood Finishes: A key component in varnishes and stains for furniture and flooring, enhancing durability and appearance.
• Corrosion-Resistant Primers: Formulated into primers for steel and other substrates to provide a protective barrier.
• Marine Coatings: Utilized in coatings for ships and offshore structures due to its resistance to moisture and environmental degradation.

Quality Control

Our Tall-Linseed Oil/Phthalic Anhydride/Glycerol Resin is manufactured under a stringent quality management system. Each batch undergoes comprehensive testing for critical parameters including acid value, viscosity, color, and solids content to ensure batch-to-batch consistency and performance in your formulations. 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, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Due to its nature, the resin is easily oxidized; prolonged storage should be under an inert atmosphere where feasible to maintain optimal properties. Keep container tightly sealed when not in use to prevent skinning and contamination.
