Description

Linseed oil, polymer with glycerol, phthalic anhydride, rosin and tung oil is a specialized alkyd resin, a synthetic polymer created by the polycondensation of natural drying oils and acids. This compound matters for its unique ability to combine the rapid drying and hardness of tung oil with the flexibility and durability of linseed oil, resulting in a high-performance film-forming agent. It is primarily needed by manufacturers in the coatings, inks, and adhesive industries seeking to enhance product durability, gloss, and chemical resistance. The CAS number for this material is 68015-28-1.

Application

This versatile alkyd resin is engineered for demanding applications where film integrity and performance are critical.

• High-Performance Industrial Coatings: Used as a primary binder in protective coatings for metal substrates, machinery, and agricultural equipment due to its excellent adhesion and corrosion resistance.
• Printing Inks: Serves as a key resin in specialty printing inks, particularly for overprint varnishes and metal decoration, providing high gloss and rub resistance.
• Wood Finishes and Varnishes: Formulated into clear and pigmented varnishes for furniture and flooring, offering a tough, durable finish with good moisture barrier properties.
• Adhesives and Sealants: Acts as a tackifying and strengthening agent in certain adhesive formulations, improving bond strength and flexibility.
• Marine and Anti-Corrosive Paints: An essential component in primers and topcoats for marine environments, leveraging its resistance to water and oxidation.
• Artists' Paints and Mediums: Used in the formulation of high-quality oil paints and painting mediums to modify drying time and film characteristics.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as acid value, viscosity, solids content, and color are strictly monitored. 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 material is easily oxidized; containers should be kept tightly sealed when not in use to minimize contact with air. Keep away from strong acids and organic solvents.
