Description

Resin Acids And Rosin Acids, Hydrogenated, Strontium Salts is a specialized organometallic compound derived from the hydrogenation and subsequent neutralization of rosin acids. This product is valued for its enhanced stability and unique reactivity profile compared to its non-hydrogenated counterparts, making it a critical performance additive in several industrial sectors. It is primarily sought after by manufacturers in the polymer, adhesive, and coatings industries seeking to improve product durability and modify rheological properties.

Application

• Polymer Stabilizers and Modifiers: Acts as a heat stabilizer and processing aid in PVC and other halogenated polymers, improving thermal stability during extrusion and molding.
• Adhesive Formulations: Used as a tackifier and rheology modifier in hot-melt and pressure-sensitive adhesives, enhancing bond strength and application properties.
• Protective Coatings and Paints: Functions as a driers and cross-linking agent in alkyd resins and oil-based coatings, promoting faster drying and improved film hardness.
• Grease and Lubricant Additives: Serves as a thickener and anti-corrosion agent in complex soap-based greases, providing enhanced water resistance and structural stability.
• Printing Inks: Utilized to modify viscosity and improve the gloss and rub resistance of various ink formulations.
• Rubber Compounding: Acts as a processing aid and reinforcing agent, aiding in dispersion of fillers and improving the physical properties of vulcanized rubber.
