Description

Linseed Oil, Polymer With Pentaerythritol, Phthalic Anhydride And Polymd. Linseed Oil CAS NO 68152-95-4 is a specialized alkyd resin derived from the polymerization of linseed oil with pentaerythritol and phthalic anhydride. This formulation is engineered to provide superior drying properties, flexibility, and durability in protective coatings. It is a critical raw material for manufacturers in the paints, varnishes, and industrial coatings sectors who require high-performance binders with excellent weather resistance and adhesion.

Application

• Industrial and Architectural Paints: Acts as a primary binder in air-drying alkyd paints for metal structures, machinery, and building exteriors.
• Protective Coatings and Varnishes: Used in formulations for wood finishes, marine varnishes, and anti-corrosive primers due to its excellent film formation and water resistance.
• Printing Inks: Serves as a vehicle resin in specialty printing inks, contributing to gloss and adhesion on various substrates.
• Adhesives and Sealants: Imparts flexibility and binding strength in certain adhesive and caulking compound formulations.
• Artists' Paints and Mediums: A key component in high-quality oil-based artists' paints and painting mediums for its reliable drying profile and finish.

Quality Control

Our production of Linseed Oil Alkyd Resin adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, color, and solids content are rigorously tested. Certificates of Analysis (COA) documenting these specifications are available for every shipment to support your quality assurance processes.

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 (59°F and 77°F). Keep container tightly sealed when not in use to prevent skinning and oxidation.
