Abstract: A composition in the form of a solution or dispersion, comprising an anhydride-modified polyolefin, an anhydride-modified styrenic block copolymer, and an isocyanate-containing crosslinker, wherein the anhydride-modified polyolefin and anhydride-modified styrenic block copolymer are present in a total amount in the range of 7% to 18% by weight in total, based on the composition, and in a weight ratio of anhydride-modified polyolefin to anhydride-modified styrenic block copolymer which is in the range of 2:1 to 6:1; the weight ratio of isocyanate-containing crosslinker to the sum of anhydride-modified polyolefin plus anhydride-modified styrenic block copolymer is in the range of 0.2:1 to 0.5:1; and the solvent comprises a ketone as first solvent and an alkylbenzene or an alkane solvent. The compositions are useful for adhering TPO to TPU, polyester or PU.

Abstract: A conveyor belt has a traction layer (3) in the form of a woven textile that is provided with a polymer surface coating. The surface coating is formed of a base layer (2) and a functional surface layer (1). The functional surface layer (1) has an antimicrobial additive and is substantially thinner than the base layer (2). The division of the surface coating into a base layer (2) and a functional surface layer (1) allows a effectiveness against microorganisms in the area of the conveying zone. This can be achieved by using either a lower amount of antimicrobial additive in the functional surface layer (1), being a less expensive process, and achieving just as high a concentration of antimicrobial additive. This can also be achieved by using the same amount of additive resulting in a substantially higher concentration and thus a higher effectiveness against microorganisms.
