Another method of coating industrial fabrics is powder coating (Fig. 2). This process is ideally used with relatively large wall thicknesses. Low-melting, usually colored TPU powders are applied with a doctor blade onto the substrate, sintered in an oven and the resulting surface is smoothed using rollers or embossed.
Desmopan® and Texin® are not directly supplied in powder form for this technique, but delivered in the form of granules to suitable partner companies who then produce cold-milled powder which they sell.
