A patch system and methods for using a patch system are described herein. The patch system has an elastomeric central portion configured to expand and contract over the types of distances commonly found in homes and other buildings that can result in opening and closing cracks in walls, for example. By applying the patch system across a crack under pre-tensioned conditions, opening and closing of the crack will not cause a visible defect in the wall or other surface.

Composite materials and methods of producing the same are provided. In some embodiments, the composite materials can comprise a polymer substrate, an intermediary material, such as a metal or oxide, mechanically attached onto the polymer substrate, and an elastomer bonded to the polymer substrate on the side of the polymer substrate comprising the intermediary materials. The elastomer can be bonded to the polymer substrate irreversibly, where the elastomer and the polymer substrate cannot be separated at their interface without breaking either the elastomer or the polymer substrate. In some embodiments, a primer and/or an epoxy can also be used. Uses of material sputtering or sputtered materials are also provided to bond a parylene substrate and silicone elastomer, or to enhance the relative strength of the bonding between the two. In addition, composite materials, and the use thereof, involving a parylene substrate, an elastomer receptacle, and liquid silicone are provided.

A variety of adhesive laminates are described, many of which perform functions such as liquid indication, outgassing, liquid retention, electrical conducting, and sound channeling. Also described are adhesive regions on face materials in which the regions exhibit particular dimensional proportions. Methods involving direct and transfer coating of adhesives are also described. In a particular version, a method of roll to roll transfer coating of sprayed pressure sensitive adhesives is described. Also described are various adhesive films and laminates many of which can be produced using the methods.
