Abstract:
Stocking having an upper opening, wherein said upper opening has an edge region, and a seamlessly attached antislip coating in the edge region of the upper opening of the stocking, the edge of the stocking producing a compressive pressure of from 3 to 45 mm Hg at an extension of from 10% to 350% and having a width-based flexural stiffness of at least 20 cNÃ—mm under DIN 53121 testing standards, and in the region of the stocking opening, the bond strength of the coating to the stocking being at least 3 N/cmwherein the coating comprises a polyadduct having a phase 1 and a phase 2, the mass fraction of phase 1 being greater than 60% by weight, and wherein phase 1 is a polyadduct of at least one starting material E1 and at least one starting material E3, starting material E1 comprising an oligomeric diol which has a hydroxyl number of more than 20 mg KOH/g (diol) and starting material E3 comprising a silicone-free, at least bifunctional reactive starting material having a molecular weight of less than 300 g/mol, and phase 2 is a polyadduct comprising at least one starting material E2 and at least one starting material E3, the starting material E2 having, at least in part, terminal functional groups, and the coating features a molar ratio between the starting materials E3 to be crosslinked and the sum of one or more oligomeric diols (starting material E1) and the fraction of further starting materials E2 of from 0.9 to 1.1.
