Small particle dispersion coating composition
Abstract
Abstract A SUBSTANTIALLY ODOR-FREE COATING COMPOSITION THAT PRODUCERS THICKER COATINGS OF GREATER POWER OF CONCEALMENT IN ONE-COAT APPLICATIONS THAN HERETOFORE HAS BEEN POSSIBLE, WITHOUT THE COATINGS SO APPLIED SAGGING ON VERTICAL SURFACES OR WRINKLING ON HORIZONTAL SURFACES. THE COATING COMPOSITION OF THE PRESENT INVENTION INCLUDES A PLURALITY OF COLORED PARTICLES OF AN AQUEOUS FILM FORMER, THE MAJOR PORTION OF WHICH PARTICLES ARE LESS THAN 25 MICRONS IN SIZE, DISPERSED IN AN AQUEOUS DISPERSING PHASE. THIS COATING COMPOSITION MAY BE INTERMIXED WITH: (1) DISPERSIONS OF ANOTHER COLOR TO PRODUCE RICHER COLOR EFFECTS THAN POSSIBLE WITH CONVENTIONAL PRIOR ART COATING COMPOSITIONS, (2) DISPERSIONS OF LARGER PARTICLE SIZES TO PRODUCE VISIBLE MULTICOLOR EFFECTS, AND THE COMPOSITION MAY BE DRIED AND APPLIED TO A DESIRED SURFACE IN THAT FORM, OR THE DRIED COMPOSITION MAY BE RECONSTITUTED BY THE ADDITION OF WATER THERETO.
