Description

Linseed Oil, Polymer With Formaldehyde, Glycerol, Pentaerythritol, Phenol, Phthalic Anhydride And Rosin is a complex, synthetic alkyd resin derived from natural and synthetic raw materials. This specialized polymer is engineered to deliver a unique balance of flexibility, adhesion, and chemical resistance, making it a critical component in high-performance coating formulations. It is primarily required by manufacturers in the industrial coatings, printing inks, and adhesive industries seeking to enhance product durability and application properties.

Application

• Industrial Protective Coatings: As a primary resin binder in corrosion-resistant paints for metal structures, machinery, and marine applications.
• Printing Inks: Used in the formulation of high-gloss, quick-setting inks for packaging and publication printing.
• Adhesives and Sealants: Imparts tack, flexibility, and water resistance in industrial adhesive and sealant compounds.
• Wood Finishes: A key component in varnishes and stains, providing a durable, protective film with good penetration.
• Automotive Refinish Paints: Contributes to the gloss retention, flow, and leveling properties in automotive repair coatings.
• Primers: Enhances adhesion to various substrates in primer formulations for metal and wood.

Quality Control

Our production of this alkyd resin adheres to strict batch-to-batch consistency protocols. Quality is verified through comprehensive testing of key parameters including acid value, viscosity, color, and solids content. Certificates of Analysis (COA) documenting these specifications are available for every shipment to ensure the material meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Due to its nature, the product should be stored under an inert atmosphere if long-term storage is anticipated to prevent skinning and oxidation.
