STABLE NONAQUEOUS MICROPARTICLE DISPERSIONS PREPARED FROM AMINOPLAST RESINS
A stable, nonaqueous microparticle dispersion of the polymeric reaction product of reactants containing an aminoplast resin and a hydroxyl containing material is characterized in that less than 20 percent of the polymer microparticles have a mean diameter greater than 5 microns, further characterize...

| description | A stable, nonaqueous microparticle dispersion of the polymeric reaction product of reactants containing an aminoplast resin and a hydroxyl containing material is characterized in that less than 20 percent of the polymer microparticles have a mean diameter greater than 5 microns, further characterized in that at a total solids content of 60 percent the Brookfield viscosity is less than 1000 centipoise measured at 50 RPM using a number 3 spindle at 25 DEG C, the polymeric reaction product being prepared from reactants which are substantially free of acrylic polymer. Stable nonaqueous microparticle dispersions characterized as above can also be prepared by the self condensation of an aminoplast resin. |
