50 Years of “Spirit of Colour” - ISL at Utech 2018


Already since its foundation in 1968 ISL-Chemie GmbH & Co. KG, producer of pigment pastes and paints for the polyurethane industry, has been dedicated to quality “made in Germany”. At Utech 2018 in Maastricht ISL will be presenting long-term proven products as well as new products for the colouring and coating of polyurethanes.

Moltopren®-S expanded product range

The Moltopren®-S reactive dyes product range has again been expanded. ISL will be presenting its reactive dye product range at the Berlac Group booth number 622 at this years´Utech fair. Various mixed colour shades are now available as well as basic colours red, blue and yellow. The reactive dyes of the Moltopren® S-product range are low viscous and stand out with their high colour brilliance as well as colour strength. Thanks to an optimum integration of the reactive dye via hydroxyl-functional groups into the polyurethane-foam via hydroxyl-functional groups  the so-coloured foams will not bleed. Reduced streaking and an improved settling behavior are further advantages of the Moltopren®-S product range. The product range is continuously expanded so that more and more colour shades become available.

Thermochromatic pigment pastes for “hot” applications

Foams made from PU get added value by using pigment pastes with thermochromatic pigments. The colour shade of the final product can change at a temperature at e.g. 40°C and thus shows that the coloured product still has a certain temperature. By combining thermochromatic pigments with standard pigment pastes colour shade changes can be achieved within various temperature ranges and offer functional benefits to the customer.

Special effects for PU coatings

Especially in the automotive industry high-quality surfaces with effects are more and more in demand by end-users. However, processing the expensive pigments is often challenging as they have a tendency to settle.. The desired effect is often not achieved as the pigments used can hardly be seen in the final application, for example a surface coating. Thanks to its long-term expertise with the dispersion of pigments ISL has succeeded in stabilizing special effect pigments for the use in polyurethane-coatings in a way that they can be perceived with the desired intensity in the final application, even in thicker coatings.

In-Mould-Coating for external applications

Plastic parts are coated directly in the mould using the In-Mould-Coating (IMC) process. The IMC-process is already established for the production of steering wheels, dashboards and many other applications within the automotive interior area. ISL now offers IMC-paints also for external use, for example for wheel arch linings or upper parts of rear spoilers of caravans and commercial vehicles.

The ISL-IMC-paints are self-releasing so that less external release agent is required during the moulding process. Post-painting of the parts is no longer necessary and thus time and money can be saved. The ISOTHAN®-NT-paint for corresponding applications features high surface quality, excellent UV-stability as well as very good chemical resistances.

In-Mould-Coating for Spray-Skin applications

ISL-In-Mould-Coatings stand the test in new applications like e.g. the PU-Spray-Skin method. Here an aromatic PU-system is sprayed into a pre-tempered mould. The final surface of the spray skin is refined and protected and pleasant haptics are achieved by using ISL-ISOTHAN®-In-Mould Paints which are sprayed into the mould at first. Fast colour shade changes as well as multi-coloured PU-parts are possible using spray skin technology. The technology can be used for dashboards, glove compartment lids, door trim panels or armrests and other parts and offers reduced weight as well as general costs savings compared to other technologies. The coated surfaces offer outstanding UV, abrasion and chemical resistances.

A partner to the polyurethane industry for over 50 years

ISL is more than just a product supplier. A team of experienced application engineers and developers who work closely with customers and the market enable the company to respond quickly to trends, as well as helping to shape them.  An excellent understanding of the manufacturing processes involved in producing polyurethane and comprehensive knowledge of the raw materials has made ISL a reliable partner to the polyurethane industry for over 40 years now.

The ISL Team is looking forward to the visit of customers and interested parties at its booth No. 622 at Utech in Maastricht from 29.-31.05.2018.
