Description

Fatty Acids, Tall-Oil, Polymers With Glycerol, Maleic Anhydride And Rosin CAS NO 68605-77-6 is a specialized polymeric resin derived from renewable tall oil fatty acids, modified with glycerol, maleic anhydride, and rosin. This engineered polymer offers a unique combination of tack, adhesion, and film-forming properties, making it a valuable alternative to petroleum-based resins. It is primarily used by formulators in the adhesives, coatings, and ink industries seeking to enhance product performance with bio-based components.

Application

• Hot Melt Adhesives (HMAs): Functions as a key tackifier and modifier, improving adhesion to various substrates including paper, cardboard, and certain plastics.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack and peel strength in formulations for labels, tapes, and graphic films.
• Industrial and Protective Coatings: Used as a resin modifier to enhance gloss, drying time, and water resistance in alkyd and other coating systems.
• Printing Inks: Acts as a resinous component in solvent-based and oil-based inks, contributing to gloss, rub resistance, and pigment wetting.
• Rubber Compounding: Serves as a processing aid and tackifier in various rubber products.
• Sealants and Caulks: Provides adhesion and flexibility in construction and automotive sealant formulations.

Quality Control

Our production of Fatty Acids, Tall-Oil, Polymers With Glycerol, Maleic Anhydride And Rosin adheres to stringent quality management protocols. Each batch is tested against key parameters including acid value, softening point, color, and viscosity to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket) to preserve product integrity. Keep away from heat sources and open flame.
