Description

Rosin, Maleated, Polymer With Ethylene Glycol And Methanol is a chemically modified rosin derivative engineered for enhanced performance in demanding industrial formulations. This specialized polymer offers superior adhesion, compatibility, and stability compared to unmodified rosin, making it a critical component for high-performance coatings and adhesives. It is primarily utilized by manufacturers in the paint, ink, adhesive, and polymer modification industries seeking to improve product durability and functional properties.

Application

• Adhesive Formulations: Acts as a key tackifier and modifier in hot-melt, pressure-sensitive, and structural adhesives, enhancing bond strength and thermal stability.
• Industrial Coatings & Inks: Used in resin systems for protective coatings, varnishes, and printing inks to improve gloss, hardness, and drying characteristics.
• Polymer Modification: Serves as a reactive intermediate or compatibilizer in the synthesis and modification of polyesters and other polymers.
• Paper Sizing: Employed in the production of paper and paperboard to improve water resistance and printability.
• Rubber Compounding: Functions as a processing aid and reinforcing agent in various rubber products.
• Soldering Flux: A component in flux formulations for electronics assembly, promoting solder flow and preventing oxidation.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry specifications. Key parameters such as acid value, softening point, color, and viscosity are strictly monitored. A Certificate of Analysis (COA) documenting these results is available for every batch upon request, providing full traceability and quality assurance for your manufacturing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). As the material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage of bulk quantities. Keep away from heat sources and open flame.
