Bayer MaterialScience Develops innovative Coatings ‘Crosslinker’

Initially designed for gentle textiles, Imprafix 2794 offers advantages for automotive OEM coating applications.

With the polyurethane dispersion Imprafix® 2794 XP, Bayer MaterialScience has developed a high-performance crosslinking agent for the coating of temperature-sensitive textile fibers. The new crosslinker also offers advantages for additional applications. For instance: the baking coating of perfume bottles or fine dining glassware is usually performed at temperatures above 180 °C. With many conventionally blocked crosslinkers, deblocking at such temperatures is associated with clearly perceptible yellowing. Not so with the new product, in which the isocyanate groups are blocked with dimethylpyrazole (DMP). The decorative coatings produced are dishwasher-safe and lightfast.

Imprafix® 2794 XP is also an alternative to other polyisocyanate crosslinkers for baking coatings used in automotive OEM coating applications. Formulations based on the new crosslinker can be applied as a filler, for example, and offer good protection against mechanical loads and stone chipping.

The complete release is available online.
