example 1
[0037] This example of a specific implementation of the inventive subject matter describes a first backing carrier A for applying a non-slip layer B to a hockey stick blade, as figure 1 shown. The backing carrier A of the anti-slip layer B has two layers. The first layer of the backing carrier A is formed by a network 2 from high-strength polyester fibers with the following parameters:
[0038]
[0039] The original network 2 of fibers from the backing carrier A of the anti-slip layer B has a hydrophobic impregnation and a heat treatment with high temperature, aimed at the dimensional stabilization (fixation) of the material. For the first layer treated in this way, formed by a network of fibers 2, a coating (second layer of resin or adhesive 3) is applied with a weight of 42.3 g / m 2 And the content is: Polyurethane and Acrylic. After hydrophobic impregnation, dimensional stabilization (fixation) and coating application, the material has the following parameters:

example 2
[0076] This example of a specific implementation of the inventive subject matter describes a first non-slip layer B for application on the backing carrier A of the above examples 1 and 1a. The first anti-skid layer B is in figure 2 displayed in . It is formed by a third layer of resin 5 with a thickness of at most 0.1 mm and a weight of at most 250 g / m 2 , the content is epoxy and / or phenol, such as bisphenol A based epoxy resins. It was applied only to the front side of backing Carrier A of Examples 1 and 1a.
example 3
[0078] This example of a specific implementation of the subject matter of the invention describes a second non-slip layer B for application on the backing carrier A of examples 1 and 1a above. The second anti-slip layer B is image 3 displayed in . It is formed by a third layer of resin 5 with a thickness of at most 0.1 mm and a weight of at most 250 g / m 2 , content of epoxides and phenols, such as bisphenol A-based epoxy resins (applicable only to the front side of the backing carrier A of Examples 1 and 1a). Furthermore, it contains coarsening particles 6 covering a maximum of 50% of its surface.
