Description

Alkenes, ethylene-manuf.-byproduct dicyclopentadiene-conc., polymers with bisphenol A, p-tert-butylphenol, formaldehyde, polymd. linseed oil and steam-cracked petroleum distillates is a complex, high-performance hydrocarbon resin derived from multiple petrochemical and natural feedstocks. This specialized polymer blend is engineered to deliver exceptional tack, adhesion, and water resistance, making it a critical formulating component. It is primarily sought by manufacturers in the adhesive, sealant, coating, and rubber compounding industries for its ability to enhance product durability and performance. CAS No. 129311-48-4.

Application

This versatile hydrocarbon resin finds use in numerous industrial formulations where robust performance is required.

• Hot-Melt and Pressure-Sensitive Adhesives (PSA): As a key tackifier and modifier to improve initial grab, peel strength, and thermal stability.
• Industrial and Protective Coatings: To increase hardness, chemical resistance, and drying time in alkyd-based paints and varnishes.
• Rubber Compounding: As a processing aid and reinforcing agent in tire, belt, and mechanical goods production.
• Sealants and Caulks: To enhance flexibility, adhesion to various substrates, and long-term weatherability.
• Printing Inks: As a resinous vehicle to improve gloss, rub resistance, and pigment wetting.
• Foundry Core Binders: Acting as a binding agent in sand molds for metal casting.

Quality Control

Our production of this hydrocarbon resin adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as softening point, color, acid value, and viscosity are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are available for every shipment upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and oxidizing agents. Under these conditions, the product is stable for at least 24 months from the date of manufacture.
