Description

Linseed Oil, Phthalic Anhydride, Pentaerythritol Resin CAS NO 67785-26-6 is a specialized alkyd resin synthesized from linseed oil, phthalic anhydride, and pentaerythritol. This formulation is engineered to deliver superior drying properties, excellent flexibility, and enhanced durability in protective coatings. It is a critical raw material for manufacturers in the paints, varnishes, and industrial coatings sectors seeking high-performance, environmentally compliant binder solutions. The resin's balanced composition offers a robust combination of hardness and elasticity for demanding applications.

Application

• High-Performance Industrial Coatings: Used as a primary binder in corrosion-resistant primers and topcoats for metal structures, machinery, and automotive parts.
• Architectural Paints and Varnishes: Formulated into durable exterior house paints, trim paints, and clear wood varnishes that require good weathering resistance.
• Printing Inks: Serves as a vehicle in specialty printing inks, contributing to gloss, adhesion, and drying speed on various substrates.
• Marine Coatings: Employed in anti-fouling and protective paint systems for ships and offshore structures due to its water resistance and film integrity.
• Maintenance and Protective Coatings: A key component in coatings for bridges, storage tanks, and industrial flooring that demand long-term protection.
• Wood Finishes: Used in the formulation of furniture lacquers and floor finishes to enhance depth of color and provide a protective, durable film.

Quality Control

Our alkyd resins are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Key parameters such as acid value, viscosity, solids content, and color are rigorously tested against internal and customer specifications. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee compliance and 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). Keep away from heat sources and open flame. To prevent skinning or oxidation, ensure containers are properly sealed after each use. Under recommended conditions, the product has a typical shelf life of 12 months from the date of manufacture.
