A paint manufacturing method includes receiving each of a group of fluid prepaints at different inputs of a fluid component mixing system, determining at a computer system a first fluid prepaint ratio, and mixing the fluid prepaints in accordance with the first ratio to form a base paint at an output of the mixing system. A paint manufacturing system includes a computer-controlled prepaint mixing system. The prepaint mixing system includes multiple fluid inputs providing for computer-controllable flow of prepaints into the mixing system. The computer system includes a memory storing software instructions that configured the computer system to receive user input selecting a base paint to be produced, determine a ratio of fluid prepaints needed to produce the base paint, and regulate each fluid flow control to establish, in the determined ratio, a flow of fluid prepaints entering the fluid mixing system. A paint manufacturing system includes multiple paint manufacturing sites that can each produce paint products. Each manufacturing site includes a site control computer to control a paint manufacturing process at the site and the system also includes a coordinating computer system that can exchange manufacturing operations data with each of the site control computers.

Distributed paint manufacturing system

Sets of prepaints useful for forming a road-marking paint line are provided. Also provided are methods which permit the person applying the road-marking paint to vary the properties of the road-marking paint at the application point to suit the ambient conditions, including temperature, humidity, traffic flow and the like.

Prepaints and method of preparing road-marking paints from prepaints

Composite particles and a method of preparing the composite particles are provided. The composite particles contain titanium dioxide particles with adsorbed two-phase polymer particles. The two-phase polymer particles have a soft polymer phase and a hard polymer phase in which the weight ratio of the hard polymer phase to the soft polymer phase is in the range of 10:1 to 1:5. The composite particles containing the two-phase polymer particles have improved aqueous stability and provide coatings with improved scrub resistance.

Polymer-pigment composites

Methods of providing a paint line containing a latex polymeric binder are described. A range of paints can be formulated using sets of prepaints, at least one of which contains a latex polymeric binder. The paints may be applied as architectural coatings, industrial coatings, graphic arts coating, elastomeric coatings, and non-cementitious, aggregate finish coatings suitable for application on a wall directly or as a topcoat in exterior insulation finishing systems.

Prepaints and methods of preparing paints from the prepaints

Polymer-pigment composites, aqueous dispersions of polymer-pigment composites and coating compositions containing the polymer-pigment composites are disclosed, wherein the polymer is formed from terminally-unsaturated oligomers containing acid functionality.
