Description

Zinc Resinate is a zinc salt of rosin acids, primarily abietic acid, valued for its ability to modify the properties of polymers and coatings. This compound is essential for enhancing adhesion, hardness, and drying characteristics in various formulations. It is a critical component for manufacturers in the paint, ink, adhesive, and varnish industries seeking to improve product performance and durability.

Application

• Paint and Varnish Driers: Acts as a through-drying agent and stabilizer in oil-based paints, varnishes, and enamels to accelerate the oxidation and polymerization process.
• Printing Inks: Used as a gelling agent and viscosity modifier in gravure and lithographic inks to improve gloss, rub resistance, and drying speed.
• Adhesives and Sealants: Functions as a tackifier and reinforcing agent to enhance bond strength, heat resistance, and cohesion in hot-melt and pressure-sensitive adhesives.
• Paper Sizing: Employed in the production of paper and paperboard to improve water resistance and surface strength.
• Rubber Compounding: Serves as a processing aid and activator to improve the dispersion of fillers and the vulcanization process.
• Wood Preservatives: Incorporated into coatings and treatments for wood to provide water repellency and fungistatic properties.

Quality Control

Our Zinc Resinate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including zinc content, softening point, acid value, and solubility. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
