Description

Linseed Oil, Polymer With Glycerol And Phthalic Anhydride is a synthetic resin derived from the alkyd family, specifically a modified alkyd resin. This compound is valued for its excellent film-forming properties, durability, and adhesion, making it a crucial component in high-performance coatings. It is primarily sought after by manufacturers in the paints, varnishes, printing inks, and industrial coatings sectors who require reliable, long-lasting finishes.

Application

• Industrial and Architectural Paints: Used as a primary binder in air-drying and baking enamels for metal and wood substrates.
• Protective Coatings and Varnishes: Provides a tough, flexible, and weather-resistant film for machinery, furniture, and flooring.
• Printing Inks: Serves as a key resin in offset and lithographic inks, contributing to gloss, rub resistance, and drying properties.
• Primers and Undercoats: Enhances adhesion to difficult surfaces and provides a stable base for topcoats.
• Marine Coatings: Employed in formulations requiring resistance to water and environmental degradation.
• Adhesives and Sealants: Acts as a tackifying and film-forming agent in specific adhesive systems.
