Description

Polymers With Glycerol And Maleated Rosin is a synthetic resin derived from the esterification of glycerol with maleated rosin. This compound is valued for its excellent film-forming, adhesive, and tackifying properties, making it a versatile intermediate and additive. It is primarily used in industrial applications where enhanced adhesion, water resistance, and polymer modification are required. The CAS number for this substance is 68152-63-6.

Application

• Adhesive Formulations: Acts as a key tackifier and modifier in hot-melt, pressure-sensitive, and structural adhesives.
• Polymer Modification: Used to improve the compatibility, flexibility, and adhesion properties of various polymer blends.
• Coatings and Inks: Serves as a film-forming agent and resin in protective coatings, varnishes, and printing inks.
• Rubber Compounding: Functions as a processing aid and tackifier in rubber products to enhance cohesion.
• Sealants and Caulks: Imparts durability and adhesion in construction and industrial sealant formulations.
• Paper Sizing: Used to improve the water resistance and strength of paper and paperboard.

Quality Control

Our Polymers With Glycerol And Maleated Rosin is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance in key parameters such as acid value, softening point, and color. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee product integrity and traceability.

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 maintain product stability. Keep away from strong oxidizing agents.
