    Abstract: A novel process for applying cured thermoset resinous coatings to various kinds of substrates and in particular, to thin metal substrates, is disclosed. Finely divided thermosettable resinous particles containing a solid catalyst are introduced into a region of a plasma arc generated flame having a temperature greater than the melting point of said resin. The residence time of said resinous particles in the vicinity of said flame is maintained for a period sufficient to liquify substantially said particles and to initiate polymerization of the thermosettable resin particles. The liquified resin particles are propelled towards a substrate with sufficient velocity to cause said liquified resinous particles to impact with sufficient force to cause said particles to flow upon said substrate to coat same with a continuous, thin coating. The coated substrate is then cooled at a rate sufficiently slow to permit said coating to cure. The plasma flame must be located sufficiently near the substrate so that the resinous particles possess sufficient thermal and kinetic energy to flow into a thin coating retaining sufficient energy therein to continue curing to a thermoset state without addition of energy. The kinetic energy of the particle facilitates formation of a thin, uniform coating and creates additional thermal energy upon impact with said substrate.

    Abstract: The purpose of the present disclosure is to provide a pre-coating processing method and a pre-coating processing system (1) for fiber-reinforced thermoplastic member, which can achieve the coating adherence required in the field of aircraft. In a pre-coating processing method according to the present disclosure, a to-be-coated surface of a fiber-reinforced thermoplastic plastic member (2) is subjected to an activation treatment: in which the to-be-coated surface is activated under a condition such that the surface free energy of the to-be-coated surface immediately after the activation treatment reaches at least 70 mJ/m2; and in which the to-be-coated surface is heated to a temperature at which the modulus of elasticity of the to-be-coated surface becomes lower than that at normal temperature.

    Abstract: Methods and devices for coating a composite substrate. A desired design can be applied to at least a portion of a substrate's one or more surfaces by indexing the substrate, a coating apparatus, or a combination thereof, during or between application of one or more contrast coatings. The term indexing refers to changing the position (e.g. angle, tilt) of the substrate and/or the coating apparatus, the speed of such positioning, the rate at which the coating is applied, or some combination thereof. By such indexing, the pattern (4A-C) applied to the substrate (2A-C) can be varied.

    Abstract: Provided are methods for coating plastic substrates with an aqueous coating composition comprising at least one organic polymer as binder, the coating composition being applied to the surface of the plastic substrate and being subsequently cured, wherein the plastic substrate is pretreated before the coating composition is applied, the pretreatment comprising the two following separate steps in the order stated: (A) heat-treating a plastic substrate at an ambient temperature in the range from 60° C. to 160° C. for a period in the range from 1 minute to 20 minutes, (B) flaming the surface of the plastic substrate pretreated as per step (A), there being a period of up to 90 minutes between the ending of step (A) and the beginning of step (B). Additionally, provided are coated plastic substrates that have been coated by the methods of the invention.
