A hose includes an inner tube containing an alloy of NBR/PVC mixed with ECO, and the inner tube has a tube wall thickness of from 2 mm to 4 mm. A first reinforcement layer surrounds the inner tube, and includes a first yarn layer spiral wound over the inner tube in a first winding direction, as well as a second yarn layer spiral wound over the first yarn layer in a second winding direction opposite the first winding direction. A friction layer is disposed over the first reinforcement layer. A second reinforcement layer surrounds the friction layer, and includes a third yarn layer spiral wound over the friction layer in a third winding direction, and a fourth yarn layer spiral wound over the third yarn layer in a fourth winding direction opposite the third winding direction. A cover layer is disposed over the second reinforcement layer.

Linear polyfunctional polyglycidyl amine oligomeric and/or polymeric structures exhibiting at least two primary amines are described, which provide crosslinking capabilities for latex paint compositions. These crosslinkers not only exhibit latent crosslinking properties but also improve scrub resistance when compared with existing latex formulations. Once the latex is coated onto a substrate, the volatile base evaporates and the groups react to form a crosslinked coating with improved scrub resistant properties.
