Description

Linseed Oil, Polymer With p-tert-Butylbenzoic Acid, p-tert-Butylphenol, Formaldehyde, Pentaerythritol And Phthalic Anhydride CAS NO 68514-48-7 is a specialized alkyd resin derived from the polymerization of linseed oil with key phenolic and acid components. This product matters for its ability to impart excellent durability, adhesion, and chemical resistance to coatings and inks. It is primarily needed by formulators in the industrial coatings, printing inks, and adhesive industries seeking high-performance, modified resin systems.

Application

• Industrial Protective Coatings: Used as a binder in high-performance coatings for metal, wood, and concrete, offering enhanced weather and corrosion resistance.
• Printing Inks: Serves as a key resin component in specialty inks, including overprint varnishes and packaging inks, for improved gloss, rub resistance, and drying properties.
• Adhesives and Sealants: Functions as a tackifying and strengthening agent in formulations requiring strong adhesion and flexibility.
• Automotive Finishes: Employed in primer and topcoat formulations to provide a durable, protective film with good substrate wetting.
• Marine Coatings: Utilized in anti-corrosive paint systems for ships and offshore structures due to its water resistance and film integrity.
• Maintenance Paints: A critical ingredient in heavy-duty maintenance paints for industrial plants and infrastructure.

Quality Control

Our alkyd resin products undergo rigorous quality testing to ensure batch-to-batch consistency and performance. Key parameters such as viscosity, acid value, color, and solids content 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, and well-ventilated area at room temperature (15-25°C). This product is easily oxidized; containers should be kept tightly sealed when not in use to minimize exposure to air.
