Abstract
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.
