Description

Fatty Acids, Tall-Oil, Zinc Salts CAS NO 61790-11-2 is a metallic soap derived from tall oil fatty acids, a by-product of the wood pulping industry, reacted with zinc oxide. This compound serves as a versatile and cost-effective multifunctional additive, primarily valued for its role as a lubricant, release agent, and stabilizer in polymer processing. It is essential for manufacturers in the plastics, rubber, and coatings industries seeking to improve processing efficiency and final product performance.

Application

• Polymer Processing Aid & Lubricant: Widely used as an internal and external lubricant in PVC, polyolefins, and engineering plastics to reduce melt viscosity, prevent sticking, and enhance mold release.
• Rubber Industry: Acts as an activator and processing aid in rubber compounding, improving dispersion of fillers and facilitating extrusion and calendaring.
• Coatings & Inks: Functions as a wetting and dispersing agent for pigments, and as a flatting agent to control gloss in paints and printing inks.
• Adhesives & Sealants: Used as a tackifier and rheology modifier to adjust viscosity and improve application properties.
• Wood & Concrete Treatment: Employed in formulations for wood preservatives and concrete curing compounds due to its hydrophobic properties.
• Grease & Thickener: Serves as a component in the manufacture of certain lubricating greases and as a thickening agent.
