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-containing
polymer (i) to SiH-containing
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.
