Description

Tall-Soybean Oil/Rosin/Phthalic Anhydride/Pentaerythritol CAS NO 68413-11-6 is a specialized, high-performance alkyd resin intermediate or modifier, synthesized from a precise blend of tall oil/soybean oil fatty acids, rosin, phthalic anhydride, and pentaerythritol. This compound is engineered to deliver enhanced drying properties, chemical resistance, and film flexibility in coating formulations. It is a critical raw material for industrial paint, varnish, and adhesive manufacturers seeking to improve product durability and performance. The unique composition allows for tailored resin properties to meet specific application demands.

Application

• As a key resin intermediate in the formulation of high-performance industrial and architectural alkyd paints and coatings.
• Used in the production of corrosion-resistant metal primers and finishes for automotive, marine, and machinery applications.
• Serves as a modifying resin in printing inks to enhance gloss, adhesion, and drying speed.
• An essential component in wood varnishes and stains, providing excellent penetration and protective film formation.
• Employed in the manufacture of adhesives and sealants to improve bonding strength and environmental resistance.
• Used as a reactive modifier in specialty plasticizers and polymer composites.
