Description

Butarez I CAS NO 51570-42-4 is a high-purity, synthetic hydrocarbon resin derived from petroleum-based feedstocks. This product is valued for its excellent tackifying properties, thermal stability, and compatibility with a wide range of polymers. It is primarily used by formulators in the adhesives, sealants, and rubber industries to enhance performance characteristics. Its consistent quality ensures reliable processing and final product performance in demanding applications.

Application

• Pressure-Sensitive Adhesives (PSAs): A key tackifier for tapes, labels, and graphic films, improving peel adhesion and quick-stick properties.
• Hot Melt Adhesives (HMAs): Enhances bond strength, open time, and thermal stability in packaging, woodworking, and non-woven applications.
• Rubber Compounding: Used as a processing aid and reinforcing agent in tire treads, belts, hoses, and other molded rubber goods.
• Sealants and Caulks: Improves cohesion, adhesion, and flexibility in construction and automotive sealant formulations.
• Inks and Coatings: Acts as a modifier to improve gloss, hardness, and pigment wetting in specific industrial coating systems.
• Polymer Modification: Serves as a compatibilizer and property enhancer in various plastic and elastomer blends.

Quality Control

Our Butarez I is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including softening point, color, and melt viscosity. Certificates of Analysis (COA) documenting purity and physical specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from sources of heat and open flame. For long-term storage, ensure the container is kept sealed to prevent contamination and moisture absorption.
