DEFINITIONS CONCERNING COATINGS (Chapter 5.4.)

- “paint or lacquer”: preparations, including all components needed for their application, which are applied as a continuous coat on an object to provide a decorative, protective or other functional effect;

- "organic solvents": each organic substance which at a temperature of 293.15 K has a vapour pressure of 0.133 kPa or higher, or which under the specific conditions of use has a corresponding volatility, and which:

-

either separately or in combination with other agents, is used to dissolve raw materials, products, or waste;

-

or which is used as a cleaning product to dissolve soiling substances, or as a dissolving product, or as a dispersion medium, or as a viscosity-controlling product, or as a softener or preservative;

- “pre-treatment”: the removal of soiling, oil and grease, metal scales, annealing skin, mill skin or welding scale, rust or other corrosion products, old coatings, etc. from objects which have to be painted, lacquered or varnished;

- “mechanical pre-treatment”: pre-treatment in a mechanical manner such as scaling, brushing, scraping and (pneumatic, nozzle or wet) sandblasting;

- “thermal pre-treatment”: pre-treatment by burning off or flame blasting;

- “chemical pre-treatment”:

a)

chemical cleaning with:

-

an alkaline degreasing agent in degreasing baths, in spray tunnels or with a steam jet;

-

organic solvents in immersion baths, spray tunnels, by hand or in vapour degreaser appliances;

-

emulsions or with products which form emulsions during cleaning;

b)

pickling to remove oxides or a mill skin;

c)

the application of inorganic conversion coats formed by the action of chemical substances whereby the metal itself works on the coating;

- "pneumatic spraying": the nebulizing of paint using a fast air flow;

- "hot spraying": the spraying of paint where the viscosity of the paint is lowered by increasing the temperature of the paint;

- “airless spraying”: the nebulizing of paint without air flow by spraying it through a narrow, hard, metal sprayer at a very high pressure of approx. 4,000 to approx. 20,000 kPa;

- “electrostatic spraying”: the nebulizing of paint using an electrical high voltage of approx. 90 to approx. 175 kV;

- “electrophoretic coating”: the application of a coating using an immersion tank containing water-soluble coating, whereby an electrical DC current is created between the object and the wall of the tank.

- “enamelling”: the bringing to melting point of a glassy mass on objects, which are then burned in an enamelling kiln at high temperature (approx. 800 to approx. 900C) with enamel as the result;

- "muffling": the accelerated drying and hardening of lacquer coatings on objects by using object temperatures in excess of 100C.
