Description

Fatty Acids, Tall-Oil, Polymers With Ethylene Glycol, Linseed Oil, Pentaerythritol And Phthalic Anhydride is a complex, synthetic alkyd resin designed for high-performance industrial applications. This specialized polymer combines the flexibility and drying properties of fatty acids and linseed oil with the structural integrity provided by pentaerythritol and phthalic anhydride, resulting in a versatile resin intermediate. It is primarily required by manufacturers in the coatings, adhesives, and ink industries seeking to formulate products with excellent film formation, adhesion, and durability.

Application

• Industrial Coatings Binder: Serves as a key resin component in air-drying and baking enamels, primers, and maintenance paints for metal, wood, and concrete substrates.
• Printing Ink Formulation: Used in the production of lithographic and paste inks, contributing to gloss, rub resistance, and pigment wetting.
• Adhesive and Sealant Modifier: Imparts tack, flexibility, and cohesive strength to industrial adhesives, caulks, and sealants.
• Corrosion-Resistant Primer: Formulated into primers that offer excellent barrier protection and adhesion for steel and other metals.
• Wood Finishing Products: A critical ingredient in varnishes, stains, and wood sealers, enhancing depth, protection, and dry time.
• Specialty Resin Intermediate: Used as a base for further chemical modification to create resins with specific properties like increased hardness or water resistance.

Quality Control

Our alkyd resin products are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested against internal specifications. Certificates of Analysis (COA) documenting these results are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized; prolonged storage should be under an inert atmosphere (e.g., nitrogen blanket) to prevent skinning and gelation. Keep away from heat sources and open flame.
