Description

Terpene Resin CAS NO 9003-74-1 is a thermoplastic hydrocarbon resin derived from terpene monomers, primarily α-pinene and/or β-pinene. This versatile resin is valued for its excellent tackifying properties, good color stability, and compatibility with a wide range of polymers and elastomers. It is a critical raw material for manufacturers in the adhesives, sealants, and coatings industries seeking to enhance performance characteristics such as adhesion, cohesion, and viscosity control.

Application

• Hot Melt Adhesives (HMAs): A primary tackifier providing excellent initial grab and bond strength in packaging, woodworking, and non-woven applications.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes, labels, and graphic films to impart permanent tack and peel adhesion.
• Rubber Compounding: Functions as a processing aid and tackifier in rubber products like tires, belts, and seals.
• Industrial and Protective Coatings: Enhances hardness, water resistance, and gloss in varnishes, paints, and printing inks.
• Sealants and Caulks: Improves adhesion, flexibility, and durability in construction and automotive sealants.
• Chewing Gum Base: Serves as a masticatory substance in food-grade formulations (subject to specific purity grades).
• Personal Care: Used as a film former and fixative in products like mascara and hairspray.

Quality Control

Our Terpene Resin is manufactured under a strict quality management system. Each batch is tested against key parameters including softening point, color, acid value, and solubility to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting these results are available upon request. We can supply grades compliant with relevant industry standards for food contact and cosmetics where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under recommended conditions, the product is stable for extended periods.
