RHOPLEX® R-253

RHOPLEX® R-253 is designed for use as an aqueous release coating, particularly for masking tapes. Coated directly over creped or flat saturated tape stocks or base coated saturated tape stock, RHOPLEX® R-253 offers a release surface for a typical masking tape adhesive. These release properties are retained over extended storage periods as indicated by accelerated high temperature/high humidity aging tests.
