- Binders for alkyd-based paints fulfill this dual requirement.
- these alkyd binders have the disadvantage of having low chemical resistance to solvents such as methyl ethyl ketone or aromatics such as xylene and vis-à-vis acids and they are sensitive to UV.

It is for this reason that the term "powder coatings" used in industry generally refers to thermosetting powder coatings. These paints are easily sprayed electrostatically or tribostatically onto the substrate: as the thickness increases, the paint "self-polishes” to produce a relatively homogeneous film thickness. The object painted with the powder is then dried in the oven. The powder melts and forms a continuous film, before chemically reacting and becoming a solid and inert coating. They have a number of advantages over traditional liquid paints, especially with regard to the environment since they are 100% solid, they contain virtually no volatile organic compounds. Emissions to the environment are negligible. The process of manufacture of powder paints and their mode of application is described in the following paragraphs:

- the mixture of heat and friction caused by the shearing of the screws, melts the resin and thoroughly mixes all the other ingredients (mainly pigments and fillers), dispersing them in the molten resin.
- the ingredients stay only about 15 seconds in the extrusion zone. It is therefore essential to have a homogeneous premix to obtain a homogeneous powder paint.
- the mixture leaves the extruder in the form of a hot liquid (c 130 0 C) extremely viscous. Since the resin is thermosetting, it is imperative to cool the mixture as fast as possible to avoid any hardening reaction.

- grafted present in the starting emulsion before drying Following this redispersion, the particle size of the reconstituted graft copolymer obtained is measured by laser granulometry. The more the particle size of the reconstituted graft copolymer is close to that of the graft copolymer used in the synthesis of the pulverulent composition, the better is the redispersibility.

If it is binders used in coating compositions, this better resistance to solvents and better mechanical strength will increase their life or the duration of their presence on the substrate they protect. Their resistance to aging can also be increased. Their resistance to dimensional variations of the support can also be increased.

- the specimens are allowed to stand for at least 12 hours in a room where the temperature is (23 ⁇ 3 ° C) and the relative humidity is (55 ⁇ 10%).
- the specimen is attached to the platform for rotating the specimen.
- the horizontality of the device is checked using the spirit level.
- the oscillating arm equipped with a diamond point is applied to the film of varnish, the weight being adjusted so as to have the lowest pressure.
- the specimen is rotated.
- the scratch resistance result is the minimum gram pressure for the appearance of a continuous and regular streak obtained by calculating the average of 2 successive determinations carried out at 2 different places of the same test piece.
- This example relates to the evaluation of the two binders of the invention dried in pure form at 23 ° C. and 55% relative humidity for one month.
- Table 1 summarizes the products tested and their comparative
- the copolymer according to the invention has improved mechanical characteristics which are characterized by: a greater hardness; an increase in the maximum stress while maintaining a significant level of deformation; - greater resistance to scratching.
- Table 6 summarizes Taber scratch resistance results. We note the pressure in grams necessary for the formation of a scratch. Table 6
- This example concerns the evaluation of the binder of Example 1 of the invention dried so as to form a pure binder film under optimum conditions in terms of crosslinking: a drying agent was therefore added and dried at high temperature. .
- Table No. 7 shows the test products examples according to the invention or comparative examples as well as the duration and the drying temperature for each of the products.
- Table 12 summarizes Taber scratch resistance results. We note the pressure in grams necessary for the formation of a scratch. Table 12
- the graft copolymer of Example 1 of the invention has mechanical characteristics further improved by further crosslinking (addition of driers) which are characterized by:
