Description

Fatty acids, soya, polymers with glycerol and phthalic anhydride Alkyd resin 342 is a specialized, long-oil alkyd resin derived from soy fatty acids. This product is engineered to provide excellent flexibility, adhesion, and durability in formulated coatings. It is a critical raw material for manufacturers in the protective and decorative coatings industries seeking to enhance product performance and sustainability profiles.

Application

• Industrial and Architectural Coatings: A primary binder in air-drying paints and varnishes for metal and wood substrates.
• Protective Marine Coatings: Used in formulations requiring good moisture resistance and flexibility for ships and offshore structures.
• Automotive Refinish Paints: Imparts gloss retention and weathering resistance in repair coatings.
• Printing Inks: Serves as a resin vehicle for lithographic and specialty inks, contributing to gloss and rub resistance.
• Adhesives and Sealants: Acts as a tackifying and flexibilizing agent in various adhesive formulations.
• DIY and Decorative Paints: A key component in consumer-grade enamels and trim paints due to its easy application and good leveling.

Quality Control

Our alkyd resins are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested. Certificates of Analysis (COA) documenting full specifications 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 room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain product integrity. Keep away from heat and ignition sources.
