Articles comprising: (1) a sheet having a first surface and a second surface and (2) an separation layer on at least a portion of the first surface, wherein the separation layer comprising (a) a binder layer with particles entrained therein and (b) an overcoat. Also methods for making such articles and methods for using such articles.

Articles with adhesive separation layer

An adhesive composition that incorporates cationic microspheres and a fluidizing medium effective for supporting application of the adhesive composition to a substrate.

Cationic microspheres and method of making cationic microspheres

Custom footbed devices, methods of constructing the devices and kits for constructing custom footbeds are disclosed that may be particularly advantageous in the treatment of plantar ulcers. The devices offer the advantage of off-loading pressure from the plantar ulcers in a device that is easy to construct, reusable, lightweight, and custom-made to improve patient comfort. The footbeds are constructed using a curable substrate that is formed to the plantar surface of the foot except in the areas occupied by spacers designed to off-load wounds on the bottom of the foot.

Curable off-loading footwear and methods

The present invention provides an article comprising a curable resin and a filler associated with the resin. The incorporation of fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage. The incorporation of fillers into the casting materials of the present invention also imparts air and vapor porosity to the cured casting materials. If desired articles of the present invention may also incorporate fibers (either individually, bundled, or in the form of a light-weight scrim) to provide increased cohesiveness to the uncured article. Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour.

The present invention provides a silicate-containing composition for use in an orthopedic support material. The silicate-containing composition includes a water-soluble silicate, wherein at least about 1 part of the water-soluble silicate is soluble in about 6 parts water at 25.degree. C. Preferably, the water-soluble silicate has the formula SiO.sub.2 /M.sub.2 O wherein M is Li, Na, K, or NR.sub.4, wherein each R is independently hydrogen or a (C.sub.1 -C.sub.10)organic group.

Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour. The ratio of the volume of filler to volume of prepolymer or resin is &gt;0.40.

Method of making a light-weight orthopedic casting article

The present invention provides a method of preparing an orthopedic cast comprising the step of coating a porous flexible substrate with a water-curable resin composition composed of a water-reactive alkoxysilane terminated resin having at least one hydrolyzable group per molecule. The resin composition has a viscosity of no greater than about 500 Pa-s under ambient conditions and contains less than about 1 wt-% of a solvent, based on the total weight of the resin composition.
