For Rapid And Precise Hiding Power Measurements

Release Charts

Size: 7-5/8" x 10-1/4" (194 x 260mm)

These charts have a unique surface which is readily wetted by water-borne or solvent-borne paints, and from which the dried film is easily* stripped with adhesive tape.

The easy-stripping feature permits the dry film weight (M) on a measured area (A) to be determined precisely by weighing on an analytical balance before and after film removal. The spreading rate (H) or wet film thickness (T) can then be calculated using one of the familiar relationships:


Hiding Power Procedure


In which D is the density and N the nonvolatile fraction by weight of the applied paint. This procedure represents a breakthrough in reduced time for precise measurement of spreading rate (or wet film thickness) in the determination of hiding power. See Appendix which follows for detailed test procedures.

* Not so easily as to produce undamaged free films. For that purpose use Form RP-1K release paper described in Gardco general catalog.
