Catalyst For Rosin Ester
This catalyst accelerates the esterification of gum and tall oil rosin esters, shortening reaction times while improving long-term heat stability and reducing colour formation in the final ester. The active compounds are phenol sulfide or organophosphorous derivatives, designed to function as a catalyst, antioxidant and bleaching agent in one step. It is odourless, environmentally friendly and approved for food contact applications, making it suitable for use in adhesive, coating and ink formulations where regulatory compliance is critical.
The product is supplied as a dry powder or granular material, typically used in concentrations of 0.1 to 0.5 percent by weight relative to the rosin ester batch. It performs consistently across glycerine, pentaerythritol and modified rosin ester systems, maintaining stability under standard processing temperatures of 220 to 280 degrees Celsius. Its multifunctional nature eliminates the need for separate stabilisers or colour inhibitors, streamlining production without compromising performance.
Primary buyers include manufacturers of rosin-based adhesives, printing inks and coatings, particularly those targeting export markets with stringent quality and safety standards. The catalyst is packaged in 25 kg kraft bags, paper drums or carton boxes, with a shelf life of at least two years when stored in a dry, cool and shaded environment. Prompt delivery is standard, and the material is classified as non-dangerous for transport, simplifying logistics for bulk shipments.
