Polyurethane – colouring and coating.


Polyurethanes (PUs) are an integral component in countless consumer goods and industrial products. This material is used, for example, in foam, RIM, sealing compounds, coatings, lacquers and adhesives. It is essential that the colour paste integrates perfectly into the sensitive colouring system, so that product characteristics remain unchanged.

ISL’s PU colour pastes are specially tailored for use in a variety of PU systems. In order to fulfill the requirements of those systems, the different ISOPUR ranges, for example, are based on different binders. ISL products are specially developed and adapted for use in the respective PU system. Careful selection of organic and inorganic pigments with high light resistance and excellent stability ensures that the entire colour spectrum is fully covered. On request further product adaptations can be developed by us at any time, perfectly matched to your processes and systems.
