Abstract

Generally silicone materials adapted to releasably adhere to human skin don't attach readily to substrates such as fibrous substrates (e.g., woven and nonwoven webs), films, plastic, etc. Disclosed are inventive blends of low-tack materials, such as a low-tack silicone material, and a high-tack silicone material, such as a high-tack, hot-melt, silicone adhesive, that both releasably adhere to skin and join to various substrates, including fibrous substrates. Furthermore, these same blends may be disposed between, and attached to, a silicone adhesive layer and a substrate. In other words, the disclosed silicone blends may be used to join a silicone adhesive layer to a substrate.
