Description

Petroleum Resins, Alicyclic, Hydrogenated are high-performance, fully saturated hydrocarbon polymers derived from petroleum feedstocks, prized for their exceptional thermal stability, light color, and excellent compatibility with a wide range of materials. Their hydrogenated, alicyclic structure provides superior resistance to oxidation, UV degradation, and chemical attack, making them a critical component for enhancing durability and performance. This product is essential for formulators and manufacturers in the adhesives, sealants, coatings, and rubber compounding industries seeking to improve product longevity and color stability.

Application

• Hot-Melt Adhesives (HMA): As a key tackifier providing excellent adhesion, heat resistance, and low color.
• Pressure-Sensitive Adhesives (PSA): Used in tapes and labels to enhance tack, peel strength, and aging properties.
• Rubber Compounding: Acts as a processing aid and reinforcing agent in tires, belts, and hoses, improving dispersion and mechanical properties.
• Industrial & Protective Coatings: Imparts hardness, chemical resistance, and weatherability to solvent-based and powder coatings.
• Sealants and Caulks: Improves flexibility, adhesion, and long-term durability in construction and automotive applications.
• Printing Inks: Used as a binder and hardening resin to improve gloss, rub resistance, and drying time.
• Polymer Modification: As a compatibilizer and modifier for plastics like polyolefins to adjust rheology and impact strength.
