Description

Kolophonium behandelt, kondensiert mit Formaldehyd, Phenol, Alkylphenolen, Arylphenolen und ggf. mit mehrwertigen Alkoholen verestert und ggf. deren Metallsalze (Li, Ca, Mg, Zn) und ggf. modifiziert mit Kohlenwasserstoffharzen und ggf. Fettsuren is a high-performance, modified rosin derivative engineered for demanding industrial applications. This versatile chemical offers enhanced thermal stability, improved adhesion, and tailored compatibility compared to standard rosin resins. It is a critical raw material for formulators seeking to develop advanced adhesives, coatings, and polymer modifiers with superior performance characteristics.

Application

• Hot-Melt Adhesives (HMAs): Acts as a key tackifier and viscosity modifier, providing excellent initial grab and bond strength.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes and labels to enhance peel adhesion, tack, and cohesive strength.
• Inks and Coatings: Serves as a resin modifier to improve gloss, hardness, and drying time in printing inks and protective coatings.
• Rubber Compounding: Functions as a processing aid and reinforcing agent, improving tack and dispersion of fillers.
• Polymer Modification: Used to modify the properties of synthetic polymers, enhancing compatibility and performance in composite materials.
• Sealants and Caulks: Improves adhesion to various substrates and provides flexibility in formulated sealant products.
