Abstract: Copolymers of 23 to 92% by weight of methyl methacrylate, 5-62% by weight of an acrylic acid ester containing from 1 to 12 carbon atoms in the ester portion or a methacrylic acid ester containing from 2 to 12 carbon atoms in the ester portion and 3 to 15% by weight of unsaturated copolymerizable carboxylic acids are homogeneously mixed with triglycidyl isocyanurate, cellulose acetobutyrates and optionally with pigments and levelling agents. The mixture may be applied by electrostatic powder-spraying or other powder coating processes to suitable surfaces and cured at temperatures of about 130* to 220*C. The backed films of the mixture show outstanding adherence to the substrate and hardness coupled with elasticity, high gloss and weather resistance.

Abstract: Electrostatic deposition is utilized to coat surfaces of materials with polystyrene particles. The surfaces are coated with an electrically-conductive adhesive. Then, an electrostatic field is set up between the adhesive surface and an electrode on an applicator which may or may not be connected to a continuous feed machine for polystyrene particles. Polystyrene particles are given an electrical charge when in contact with the electrode and are propelled by the electrostatic field to the adhesive surface.

Abstract: This disclosure relates to electrostatic charges and particularly to a device that can either charge or discharge the electrostatic potential of a body with respect to its environment. More particularly, this invention relates to the use of a conductive liquid expelled from a nozzle positioned in a strong electrostatic field, wherein the liquid is converted to fine, charged droplets to form an ionic current away from the nozzle. The nozzle and any associated equipment is charged or discharged accordingly. If the polarity of the electrostatic field in which the droplets are formed is reversed, the opposite polarity of charge or discharge will occur.
