  "Dip coating" means a method of applying coatings to a substrate by submersion into and removal from a coating bath.

  "Electric-insulating varnish" means a non-convertible-type coating applied to electric motors, components of electric motors, or power transformers, to provide electrical, mechanical, and environmental protection or resistance.

  "Electric-insulating and thermal-conducting" means a coating that is characterized as having an electrical insulation of at least 1000 volts DC per mil on a flat test plate and an average thermal conductivity of at least 0.27 BTU per hour-foot-degree-Fahrenheit.

  "Electrostatic application" means a method of applying coating particles or coating droplets to a grounded substrate by electrically charging them.

  "Etching filler" mean a coating that contains less than 23% solids by weight and at least 0.5% acid by weight, and is used instead of applying a pretreatment coating followed by a primer.

  "Extreme high-gloss coating" means a coating which, when tested by the American Society for Testing Material (ASTM) Test Method D-523 adopted in 1980, shows a reflectance of 75 or more on a 60 degree meter.

  "Extreme performance coatings" means coatings designed for harsh exposure or extreme environmental conditions.

  "Flow coat" means a non-atomized technique of applying coatings to a substrate with a fluid nozzle in a fan pattern with no air supplied to the nozzle.

  "Hand lettering" means an application method utilizing small paint markers, paint brush, or other similar appliance that is administered by hand application equipment to add identification letters, numbers, or markings on a substrate.

  "Heat-resistant coating" means a coating that must withstand a temperature of at least 400 degrees Fahrenheit during normal use.

  "High-performance architectural coating" means a coating used to protect architectural subsections and which meets the requirements of the Architectural Aluminum Manufacturer Association's publication number AAMA 605.2-1980.

  "High-temperature coating" means a coating that is certified to withstand a temperature of 1,000 degrees Fahrenheit for 24 hours.

  "High-volume, low-pressure (HVLP) spray" means a coating application system which is designed to be operated and which is operated between 0.1 and 10 pounds per square inch gauge (psig) air pressure, measured dynamically at the center of the air cap and the air horns.

  "Magnetic data storage disk coating" means a coating used on a metal disk which stores data magnetically.

  "Medical device" means an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent or other similar article including any component or accessory, that is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or any function of the body. For the purpose of this rule, a medical device shall also include associated manufacturing or assembly apparatus.

  "Metallic coating" means a coating which contains more than 5 grams of metal particles per liter of coating, as applied.

  "Military specification coating" means a coating applied to metal parts and products and which has a formulation approved by a United States military agency for use on military equipment.

  "Mold-seal coating" means the initial coating applied to a new mold or repaired mold to provide a smooth surface which, when coated with a mold release coating, prevents products from sticking to the mold.

  "Multi-component coating" means a coating requiring the addition of a separate reactive resin, commonly known as a catalyst or hardener, before application to form an acceptable dry film.

  "One-component coating" means a coating that is ready for application as it comes out of its container to form an acceptable dry film. A thinner, necessary to reduce the viscosity of the coating, is not considered a component.

  "Pan backing coating" means a coating applied to the surface of pots, pans, or other cooking implements that are exposed directly to a flame or other heating elements.

  "Prefabricated architectural component coatings" means coatings applied to metal parts and products that are to be used as an architectural structure or their appurtenances including, but not limited to, hand railings, cabinets, bathroom and kitchen fixtures, fences, rain-gutters and down-spouts, window screens, lamp-posts, heating and air conditioning equipment, other mechanical equipment, and large fixed stationary tools.

  "Pretreatment coating" means a coating which contains no more than 12% solids by weight, and at least 0.5% acid, by weight, is used to provide surface etching, and is applied directly to metal surfaces to provide corrosion resistance, adhesion, and ease of stripping.

  "Primer" means a coating applied to a surface to provide a firm bond between the substrate and subsequent coats.

  "Repair coating" means a coating used to recoat portions of a part or product which has sustained mechanical damage to the coating.

  "Safety-indicating coating" means a coating which changes physical characteristics, such as color, to indicate unsafe condition.

  "Silicone release coating" means any coating which contains silicone resin and is intended to prevent food from sticking to metal surfaces.

  "Solar-absorbent coating" means a coating which has as its prime purpose the absorption of solar radiation.

  "Solid-film lubricant" means a very thin coating consisting of a binder system containing as its chief pigment material one or more of molybdenum disulfide, graphite, polytetrafluoroethylene (PTEF) or other solids that act as a dry lubricant between faying surfaces.

  "Stencil coating" means an ink or a coating which is rolled or brushed onto a template or stamp in order to add identifying letters, numbers, or markings to metal parts and products.

  "Textured finish" means a rough surface produced by spraying and splattering large drops of coating onto a previously applied coating. The coatings used to form the appearance of the textured finish are referred to as textured coatings.

  "Repair and touch-up coating" means a coating used to cover minor coating imperfections appearing after the main coating operation.

  "Vacuum-metalizing coating" means the undercoat applied to the substrate on which the metal is deposited or the overcoat applied directly to a metal film.
