Description

Kolophonium, maleiniert/ fumariert, kondensiert mit Formaldehyd, Phenol, Alkylphenolen, Arylphenolen u. ggf. mit mehrwertigen Alkoholen verestert u. ggf. deren Metallsalze (Li, Ca, Mg, Zn) u. ggf. modif. mit Kohlenwasserstoffharzen auf Basis C5-C9 is a complex, high-performance modified rosin resin designed for demanding industrial applications. This product matters because it offers a unique combination of tack, adhesion, and compatibility derived from its multi-stage synthesis involving maleinization/fumarization, phenolic condensation, esterification, and hydrocarbon modification. It is essential for formulators in the adhesives, coatings, and ink industries who require tailored resin solutions with specific rheological, solubility, and metal-ion characteristics to solve complex bonding and film-forming challenges.

Application

• Hot-Melt Adhesives (HMAs): As a key tackifier and modifier to enhance open time, specific adhesion to difficult substrates (e.g., plastics, metals), and thermal stability.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes and labels to provide balanced peel, tack, and shear strength, with hydrocarbon modification improving compatibility with synthetic rubber and acrylic polymers.
• Printing Inks: Serves as a resinous vehicle and gloss improver, particularly in gravure and flexographic inks, offering good pigment wetting and solvent release.
• Industrial Coatings: Imparts hardness, chemical resistance, and improved adhesion to metal substrates in protective and primer coatings.
• Rubber Compounding: Acts as a processing aid, tackifier, and reinforcing resin in rubber products such as tires and industrial rubber goods.
• Polymer Modification: Used as a reactive modifier or compatibilizer in engineering plastics and composite materials.
• Sealants and Caulks: Provides body, adhesion, and flexibility in non-curing and curing sealant formulations.

Quality Control

Our production of this modified rosin resin adheres to a strict quality management system. Each batch undergoes rigorous in-process and final testing to ensure consistent performance in key parameters such as acid value, softening point, color, and viscosity. Certificates of Analysis (COA) detailing these specifications are available upon request. While not a pharmaceutical ingredient, our manufacturing controls and documentation support compliance with relevant industrial and supply chain standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperatures (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for at least 24 months from the date of manufacture.
