Silicone adhesive compositions and their use in securing medical appliances to mammalian body

An adhesive composition comprises: 50-90 wt% of uncured silicone gel adhesive comprising a blend of a polyorganosiloxane with at least one aliphatically unsaturated group, an organosiloxane with at least one silicone-hydride group and an addition curing catalyst; 1-50 wt% of a non-silicone hydrophilic liquid additive; 0.1-10 wt% of a cohesive strengthening agent; and trace-20 wt% of at least one siloxane resin. Claimed is the adhesive as an ostomy adhesive and as an adhesive wound dressing. The adhesive may be coated on a skin surface or peri-skin of a mammalian body and then cured. The invention is a skin friendly silicone adhesive which may be used to secure medical appliances to mammalian body and to protect and treat peri-skin surface.
