COATING DISPERSION

摘要

A dispersion having from one to sixty percent by weight of total dispersion of a solids component dispersed in an organic continuous phase is useful as a coating for substrates. The solids component contains 40-95 weight-percent of a polyolefin containing only carbon and hydrogen and that has a number average molecular weight that is greater than 400 gram per mole, 5-40 weight-percent of an amine salt of a functionalized polyolefin; and 0-20 weight-percent of optional additives, wherein weight-percent is based on total weight of solids and wherein the dispersed particles have an average particle size of less than 35 micrometers and the organic phase is a dispersion support medium for the polyolefin and amine salt of a functionalized polyolefin.

1. A dispersion comprising from one to sixty percent by weight of total dispersion of a solids component dispersed in an organic continuous phase wherein the solids component comprises a blend of :
a. 40-95 percent by weight of a polyolefin containing only carbon and hydrogen and that has a number-average molecular weight that is greater than 400 grams per mole as determined by gel permeation chromatography; b. 5-40 percent by weight of an amine salt of a functionalized polyolefin; and c. 0-20 percent by weight of optional additives;wherein the percent by weight of the polyolefin component (a), the amine salt of a functionalized polyolefin (b) and optional additives (c) are relative to total solids weight, the solids are dispersed as particles and the polyolefin component (a) and the amine salt of a functionalized polyolefin (b) have an average particle size as determined by optical microscopy of less than 35 micrometers and wherein the organic continuous phase and polyolefin (a) and amine salt of a functionalized polyolefin (b) are selected so that the organic continuous phase is a dispersion support medium for polyolefin (a) and amine salt of a functionalized polyolefin (b).
