FIELD: materials.SUBSTANCE: product of in general sheet shape providing the possibilities of adjustment at installation and further removal including a layer containing a material on base of rubber crumb and having the first and the second sides. To the first or the second side a rough fabric material is attached. Part of the open surface of the rough fabric material is coated with a pressure-sensitive weak adhesive. Adhesive is considered to be weak if after holding for setting for 24 hours the strength of adhesion for separation at the angle of 90° at the rate of 300 mm/min measured as per the testing method of FINAT No. 2 is between 1.77 and 3.96 newton for the width of 25 mm at room temperature (23 °C ± 1 °C) and the relative humidity of 50 % ± 5 %.EFFECT: invention provides a surface with increased adhesion with most surfaces, with which it contacts.9 cl, 5 dwg, 2 tbl |
