Description

Linseed Oil,Polymer With Glycerol,Phthalic Anhydride And Styrene CAS NO 68389-83-3 is a specialized alkyd resin, a synthetic polymer derived from the reaction of linseed oil, glycerol, phthalic anhydride, and styrene. This compound is engineered to provide a unique balance of flexibility, adhesion, and rapid drying properties, making it a critical component in high-performance coating formulations. It is primarily used by manufacturers in the paints, coatings, and printing ink industries seeking to enhance product durability and application characteristics.

Application

• Industrial and Architectural Paints: As a key binder in solvent-borne alkyd paints, providing excellent gloss retention, weather resistance, and brushability.
• Protective Coatings for Metal: Used in primers and topcoats for machinery, agricultural equipment, and structural steel due to its strong adhesion and corrosion inhibition.
• Printing Inks: Serves as a resin vehicle in specialty printing inks, contributing to fast setting, rub resistance, and good pigment wetting.
• Wood Finishes and Varnishes: Imparts a hard, durable film with good penetration for furniture, flooring, and cabinetry finishes.
• Adhesive and Sealant Formulations: Acts as a tackifying and film-forming agent to improve bond strength and flexibility.
• Marine Coatings: Utilized in formulations requiring resistance to water and humidity for boats and offshore structures.

Quality Control

Our alkyd resins are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of tests including viscosity, acid value, solids content, and color. While this product is typically produced to industrial grade specifications, we adhere to relevant industry standards. Certificates of Analysis (COA) detailing specific lot parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, 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 away from strong acids and oxidizing agents. Under recommended conditions, the product is typically stable for 24 months from the date of manufacture.
