RHOPLEX® R-225

RHOPLEX® R-225 is designed to be used in release coatings for masking tapes. It offers tape manufacturers the application advantages of water-based systems. This polymer is simple to formulate, requires no catalyst, and offers the good initial release and re-adhesion characteristics that are obtained with solvent-based release systems.

Performance Highlights
  • The following data were obtained using test samples prepared by coating RHOPLEX® R-225 onto 30-lb. crepe stock using a No. 4 wire wound rod. The coated samples were dried 1 minute at163°C and mounted onto SS plates using double-faced tape. Selected 1-inch (2.54 cm) wide masking tapes were laminated to the coated crepe.

Product Applications
  • RHOPLEX® R-225 can be coated onto flat or creped saturated backings, offering a good release surface for the natural and synthetic rubber adhesives that
  • Typically used for masking tape applications.
  • RHOPLEX® R-225 has been successfully coated onto saturated paper with varying degrees of creping using roll coaters with knife or rod metering devices as well as with air knife coaters.
  • RHOPLEX® R-225 may be applied as received or in diluted form.
  • As is typical with most aqueous emulsion systems, RHOPLEX® R-225 is subject to foam generation.
  • Free-fall and cascading of the polymer should be minimized.
