Description

Linseed Oil, Polymer With Isophthalic Acid, Pentaerythritol And Soybean Oil is a specialized alkyd resin, a synthetic polymer derived from the polycondensation of natural drying oils and polybasic acids. This compound matters for its ability to form durable, flexible, and fast-drying protective films, offering a sustainable alternative to purely petrochemical-based resins. It is primarily needed by manufacturers in the coatings, inks, and adhesive industries seeking high-performance, bio-based binder solutions. The product is supplied under CAS No. 68082-74-6.

Application

This alkyd resin is engineered as a versatile binder and film-forming agent. Its primary applications include:

• Industrial and Decorative Coatings: As a key component in solvent-borne paints and varnishes for metal, wood, and concrete, providing excellent gloss, adhesion, and drying properties.
• Printing Inks: Used in the formulation of quick-setting offset and lithographic inks, contributing to rub resistance and gloss.
• Adhesives and Sealants: Acts as a tackifier and binder in specialty adhesives, enhancing bond strength and flexibility.
• Corrosion Protective Primers: Formulated into primers for structural steel and machinery, offering a barrier against moisture and oxidation.
• Wood Finishes: Ideal for clear coats and stains, enhancing the natural grain while providing a hard, protective surface.
• Artists' Paints and Mediums: Used in high-quality oil-based artist paints and painting mediums to modify viscosity and drying time.

Quality Control

Our production of Linseed Oil, Polymer With Isophthalic Acid, Pentaerythritol And Soybean Oil adheres to stringent quality management protocols. Each batch undergoes rigorous testing for critical parameters including acid value, viscosity, solids content, color, and drying time to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flames. Due to its nature as an easily oxidized material, it is recommended to store under an inert atmosphere or with minimal headspace after opening. Ideal storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong oxidizing agents.
