1. A curable composition for use in the care of a wound comprising distributed between at least one component A and at least one component B: one or more alkenyl group-containing polymers (i), having at least one alkenyl group or moiety in the molecule one or more SiH-containing polymers (ii), having at least one SiH units per molecule ikatalizator (iii) adding to cure alkenyl-containing polymer (i) to SiH-containing polymer (ii) the components A and B independently have a viscosity at 23 ° C in the range of 5-300 Pa, preferably 10-100 Pa s, at a shear rate of 10 B, when combined with another component have curing time at 23 ° C in the range from 0.5 minutes to 25 minutes, and when applied to a place near the wound dressing, said wound dressing covers the wound area and surrounding skin, the application is performed so that the close contact and overlap the edge of the decree constant bandage and the skin around the edges of said composition is cured in contact with said edge and the skin at 32 ° C to obtain an elastomer having a zero or low tack, for time ranging from 0.5 to less than 30 minut.2. Composition according to claim. 1, characterized in that the composition after cure, such as a sample of 1 mm in height, possesses such stretchability that the load required to obtain a 20% elongation at a tensile rate of 300 mm per minute is in the range of less than or equal to 1 4 kgf-cm width (kgf cm), preferably in the range of from 0.001 to 1.4 kgf cm, preferably expressed as a 0.001 to 14.0 kgs smdlya obtain 20% elongation, more preferably in the range of from 0.001 to 5.0 kgf see 3. composite
