Seep resistant masking material

摘要

A masking material and method of forming a masking tape that includes a substrate and an adhesive layer disposed on the substrate. The adhesive layer is preferably thicker than the substrate and formed of a material that has a modulus of elasticity combined with a viscoelastic component that allows the adhesive to conform to discontinuities associated with a surface to which the masking material is applied. Preferably, the adhesive is formed in two rows that are aligned with the lateral edges of the substrate and which prevent seepage of liquid materials between the masking material and the surface to which it is applied.

1. A masking material comprising:
a substrate having a top surface and a bottom surface, the substrate having two edges that are defined by a thickness of the substrate and that separate the top and the bottom surfaces; and an adhesive disposed on the bottom surface along at least one edge of the substrate, the adhesive extending in an outward direction from the bottom surface of the substrate to define a thickness of the adhesive that is greater than 0.03 inches and is elastically deformable at least more than 1.25 times an at rest thickness of the adhesive.
