摘要：
A curable composition for use in wound care comprising, apportioned between at least one Part A and at least one Part B: one or more alkenyl-group containing polymers (i) having at least one alkenyl group or moiety per molecule, one or more SiH-containing polymers (ii) having at least one Si-H unit per molecule and a catalyst (iii) for curing by addition of alkenyl-contatning polymer (i) to SiH-contain/ng polymer (ii), Part A and Part B independently having viscosity at 23°C in the range 5 - 300 Pa.s, preferably 10 - 100 Pa s, at a shearing rate of 10 s-1, and when combined in one Part having cure time at 23° C in the range from 0.5 min to 25 min, wherein when dispensed into a location about a wound dressing, said wound dressing overlying a wound site and skin thereabout, said dispensing being so as to intimately contact and overlie an edge of said dressing and skin about said edge, the composition cures in contact with said edge and skin at 32° C to an elastomer exhibiting zero or low tack at a time in the range from 0.5 to less than 30 minutes, apparatus for use with said composition comprising dispensing apparatus or wound dressing, a kit comprising the same, and methods of dispensing and curing the same and of using the same in sealing a wound dressing and in treating a wound site of a human in need thereof.Linvention concerne une composition durcissable sutilisant dans le traitement dune plaie et qui comprend, dune manière répartie entre au moins une partie A et au moins une partie B : un ou plusieurs polymères contenant un groupe alcényle (i) et qui comporte(nt) au moins un groupe ou une fraction alcényle par molécule, un ou plusieurs polymères contenant SiH (ii) et qui comporte(nt) au moins un motif Si-H par molécule et un catalyseur (iii), destiné à produire un durcissement lorsquun polymère contenant un alcényle (i) est ajouté à un polymère contenant SiH (ii), la partie A et la partie B présentant indépendamment une viscosité à 23° C comprise dans la plage
