NEW RAW MATERIALS FOR HYDROLYTICALLY STABLE SOFT-FEEL COATINGS
15 April 2005 - Bayer MaterialScience AG

The high quality of soft-feel coatings formulated with the new Bayhydrol® binders from Bayer MaterialScience remains unchanged, even after several days of exposure to a climate of 90 °C and 95 percent relative humidity.

The senses of sight, sound and above all touch determine whether an automobile appeals to the customer. It is for this reason that automakers like to use soft-feel coatings in vehicle interiors. Consoles, instrument panels or other plastic components coated with an ultra-thin layer of these coatings feel pleasantly soft and warm, conveying a sense of quality. Bayer MaterialScience AG has now developed raw materials with which waterborne soft-feel coatings with extremely high hydrolytic resistance can be formulated.

Coatings formulated with the new binders remain stable even after several days of exposure to a climate of 90 °C and 95 percent relative humidity. Several automakers are currently testing the coatings under these extreme conditions to ensure that the soft-feel coatings will continue to please the senses throughout the life of the car – even if the car is driven primarily in a tropical climate or is frequently parked in the glaring sun.

“The new Bayhydrol® binders are an important extension of our broad range of raw materials for soft-feel coatings,” says Dr. Torsten Pohl, a plastics coatings expert at Bayer Material Science, “because they fulfil the recently tightened specifications of the automotive industry.” The haptic properties and chemical resistance of the coatings are very good, matching – and in some cases exceeding – the quality level of established systems.

One of the binders offers an additional advantage: coatings formulated with Bayhydrol® XP 2419 adhere better to several types of plastics than do conventional coatings. Among these plastics are many ABS (acrylonitrile-butadiene-styrene) grades and blends.
