THIN DOUBLE COAT TAPES

Thin double coat tapes are described which have a total thickness of 40 to 50 micrometers
(0.0016 to 0.002 inches) in the absence of any release liners. Such tapes can be used in the areas of electronics, appliances, automotive, and general industrial products.

The thin double coat tape has a multilayer construction of:

___________________________ Liner 1

___________________________ Adhesive 1

___________________________ Backing

___________________________ Adhesive 2

___________________________ Liner 2 (optional)

Liner 1 (also known as a release liner) may be any suitable material so long as it is removable from adhesive 1 when required. Examples include polyethylene coated Kraft paper having a layer of polyethylene resin on both sides of the paper and a layer of silicone release material over the exposed polyethylene surface on one or both sides of the paper; and release coated polyester film. The thickness of Liner 1 may vary, but as an example can be in the range of 50 to 180 micrometers (0.002 to 0.007 inches).

Adhesive 1 may be any suitable pressure sensitive adhesive material, such those based on silicones, polyurethanes, natural rubbers, synthetic rubbers (eg., block copolymers), acrylics, binder resin/microspheres, and combinations thereof. Such adhesives may contain modifying agents such as tackifier resins, plasticizer resins, pigments, dyes, fillers, etc. The thickness of Adhesive 1 may vary, but as an example can be in the range...
