Contribute to lowering carbon emissions with Relcalink®, while maintaining the same performance as traditional crosslinkers.
Through the use of RelcaLink® carbodiimide crosslinkers, Stahl offers innovative solutions that enable customers to enhance the environmental profile of their products and processes, ultimately contributing to the reduction of scope 3 emissions.
Benefits
Low toxicity reduces labelling requirements
Improve chemical and scratch resistance
Quick and efficient processing: crosslinks at room temperature; no need for high temperatures
Outstanding adhesion to wide range of materials
Excellent pot-life: up to several weeks depending on pH
Swiss ordinance compliant for indirect food contact
How is Stahl’s RelcaLink® range creating the future of crosslinking?
RelcaLink® crosslinkers set a new standard, being the most sustainable, safe and easy-to-use option for high-performance crosslinking. Carbodiimides are defined as non-hazardous under GHS (Global Harmonized System), and most of Stahl portfolio is compliant for indirect food contact applications. Carbodiimides react at low temperature and offer extended pot-life, which make them easy-to-use to formulate high-performance inks, paints and coatings, from do-it-yourself to high end industrial applications.
