Description

Resin Acids And Rosin Acids, Me Esters, Polymers With Maleated Rosin And Pentaerythritol CAS NO 68554-23-4 is a specialized polymeric resin derived from modified rosin acids and pentaerythritol. This compound is engineered to provide enhanced thermal stability, tack, and adhesion properties, making it a critical performance additive. It is primarily utilized in the formulation of high-performance adhesives, coatings, and inks where durable binding and film-forming characteristics are required. The product's tailored polymer structure offers consistent quality for demanding industrial applications.

Application

• Hot-Melt Adhesives (HMAs): A key tackifier and modifier to improve adhesion strength, thermal stability, and open time.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes and labels to enhance peel adhesion, tack, and cohesive strength.
• Industrial and Protective Coatings: Imparts improved gloss, hardness, and water resistance in solvent-based and powder coatings.
• Printing Inks: Acts as a resinous binder to improve pigment wetting, gloss, and rub resistance.
• Sealants and Caulks: Provides enhanced flexibility, adhesion, and durability in construction and automotive sealants.
• Rubber Compounding: Functions as a processing aid and tackifier in various rubber formulations.
• Polymer Modification: Used as a compatibilizer or modifier to alter the properties of other base polymers.

Quality Control

Our production of Resin Acids And Rosin Acids, Me Esters, Polymers With Maleated Rosin And Pentaerythritol adheres to stringent quality management protocols. Every batch undergoes rigorous testing to ensure consistency in key parameters such as acid value, softening point, color, and viscosity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material 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 incompatible materials.
