Disclosed is a tape that includes a substrate having an adhesive layer applied thereto, and an edge coating applied to a masking edge of the tape. The substrate and the adhesive, together, define a first and a second masking edge of the tape. The edge coating includes a flocculating agent that is a polyvalent metal salt or an ionic polymer. The edge coating improves the ability of the tape to provide a sharp mask line after a paint, a varnish, a paint stripper, or other coating composition is applied to a surface where the tape is adhered.

Edge coatings for tapes

Disclosed is a tape including a substrate having an adhesive layer applied thereto and an edge coating. The substrate and the adhesive together provide at least one masking edge where the edge coating is applied. The edge coating includes a lipophilic agent, a flocculating agent, or combinations thereof. The edge coating provides the tape with enhanced masking ability by preventing paints, varnishes, paint strippers, and other coating compositions from infiltrating the tape substrate or the interface between the tape and an adherend.

A pressure sensitive adhesive composition comprising a natural or synthetic rubber and a thermoplastic polyolefin blend comprising ethylene-propylene rubber, hydrogenated polyisoprene and polypropylene.
