Description

Alkenes, Ethylene-Manuf.-Byproduct Dicyclopentadiene-Conc., Polymers With Maleic Anhydride, Soybean Oil And Steam-Cracked Petroleum Distillates is a specialized hydrocarbon resin derived from the copolymerization of dicyclopentadiene (DCPD) concentrate, maleic anhydride, soybean oil, and petroleum distillates. This product is engineered to deliver enhanced tackifying, adhesive, and hydrophobic properties, making it a critical performance additive in formulated systems. It is primarily sought by manufacturers in the adhesives, sealants, printing inks, and coatings industries for its ability to modify rheology and improve substrate adhesion.

Application

• Hot-Melt and Pressure-Sensitive Adhesives (PSA): Acts as a primary tackifier and modifier to improve peel strength and adhesion to low-energy surfaces.
• Industrial and Protective Coatings: Imparts water resistance, gloss, and improved pigment wetting in alkyd and epoxy-based coating formulations.
• Printing Inks: Used as a resinous binder to enhance ink transfer, gloss, and rub resistance in publication and packaging gravure inks.
• Rubber Compounding: Functions as a processing aid and reinforcing resin to improve the hardness and tensile properties of rubber products.
• Sealants and Caulks: Provides excellent adhesion and flexibility, contributing to the long-term durability of construction and automotive sealants.
• Foundry Core Binders: Serves as a resin component in sand core binders for metal casting, offering good thermal stability.
