Description

Fatty Acids, Tall-Oil, Polymers With Glycerol And Phthalic Anhydride CAS NO 66070-71-1 is a specialized alkyd resin intermediate, a polymeric condensation product derived from tall oil fatty acids, glycerol, and phthalic anhydride. This compound is valued for its ability to impart flexibility, adhesion, and durability to final polymer formulations. It is primarily required by manufacturers in the coatings, adhesives, and ink industries seeking to enhance product performance.

Application

This versatile polymeric intermediate serves as a key building block in numerous industrial formulations. Its primary applications include:

• As a flexibilizing and adhesion-promoting resin in air-drying and baking alkyd coatings.
• As a modifying agent in the production of industrial and architectural paints and varnishes.
• In the formulation of specialty printing inks to improve gloss and film properties.
• As a polymeric plasticizer and binder in adhesive and sealant systems.
• In the manufacture of corrosion-resistant primers and metal coatings.
• As a resin component for wood finishes and furniture lacquers.
