Bayer MaterialScience Presents New Raw Materials for Hydrolytically Stable Soft-feel Coatings

Published on 2005-04-21. Author : SpecialChem

Leverkusen -- 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.

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.

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 MaterialScience, "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.
