(B) an organic polyisocyanate, and its use to obtain a composition for coating, varnish or sealant.

Two-component aqueous binder composition based on hybrid resins based on hydroxy-functional complex of the polyester-polyacrylate and organic polyisocyanates are known, inter alia, WO 97/19118 and WO 94/13720.

WO 97/19118 describes the challenge in the aqueous phase, the polymer containing at least partially unsaturated complex polyester, whose molecular weight is in the range from 300 to 3000, IT-number is in the range from 20 to 300, an acid number of <5 mg KOH/g, where this complex polyester grafted acrylic polymer containing groups, sulfonic acid salt. The disadvantage described in this document compositions for coating water-based is the fact that they are characterized by excessive pricing if their be applied by spraying.

WO 94/13720 describes a polymer dispersion based on a complex of the polyester and acrylate, the solids content of which is in the range from 30 to 55% (wt.), which can be obtained by free-radical polymerization of from 80 to 20% (wt.), at least,

Compositions for coatings can be applied by conventional means such as spray, brush or roller, and the sputtering is preferable. Temperature curing are preferably in the range from 0 to 80°s, and more preferably from 10 to 60°C. the Composition is particularly suitable for receiving a metal substrate with the coating, such as in industries associated with final finish, h is particular in body shop, for repair of cars and vehicles, and for finishing larger vehicles, such as trains, trucks, buses, and planes.

Preferably the composition for coating of the present invention as a non-pigmented coating. From non-pigmented coatings have to be highly transparent and they should stick well to the layer of the primer coating. In addition it is required that non-pigmented coating did not change would be the aesthetic aspect of the primer coating, the passage of a coating layer to another, that is, in the bleaching primer coating due to its dissolution composition non-pigmented coatings or yellowing non-pigmented coating due to the impact of the environment outside. The non-pigmented coating composition for coating of the present invention does not have these disadvantages.

If the composition for coating will be a non-pigmented coating, a primer coating may be a conventional primer coating, known state of the art in the field of coating. Examples are solvent-free primer coating, for example Autobase® from Akzo Nobel Coatigs, based acetobutyrate cellulose and acrylate resins and a primer coating, water based, for example Autowave® by the company Akzo Nobel Coatings based on acrylate dispersion resin. In addition, a primer coating may contain pigments (pigments, the pigments that give a metallic luster, and/or pigments, creating the effect of mother-of-pearl), wax, solvents, additives that improve the filling, the neutralizing agent and defoamers. Can also be used and the primer coating with a high solids content. They, for example, based on polyols, imino and isocyanates. The composition of the non-pigmented coating applied to the surface of the primer coating, and then utverjdayut. Can be entered intermediate stage of curing the primer coating.

The invention will be illustrated by reference to the following examples. It goes without saying that these examples are offered only for a better understanding of the invention; they were not created with the assumption limit the scope of the invention in any way.

Obtaining compositions for coatings

Examples of 20-60

Water dispersion of the hybrid complex of the polyester-polyacrylate polymer (component a) were mixed with a polyfunctional isocyanate with a binder (component b) in a ratio of NCO:OH=1,5:1 or NCO:OH=1:1. The hybrid dispersion was diluted with butylglycol (10% (wt.) counting on a solid phase). Isocyanate components was diluted with metoxitpoint.com (80% (wt.) counting on a solid phase).

As the isocyanate of the staplers used two MDI, commercially available in the company Voeg:

a) Desmodur LS2025 (=Desmodur N3600) - hydrophobic isocyanurate based on 1,6-hexamethylenediisocyanate) and

b) Bahydur LS2032 (=Bayhydur N3100) - hydrophilic isocyanurate based on 1,6-hexamethylenediisocyanate modified with about 12% (wt.) methoxypolyethyleneglycol.

LS2032 and LS2025 used in a ratio of 1:1 or 2:1 in the calculation of the NCO functionality.

No catalyst is not used.

The mixture of dispersions of hybrid resin-based complex polyester-polyacrylate polymer and isocyanate components were applied to glass panels with obtaining the thickness of dry lacquer in the range from 60 to 80 μm. The panel was left to dry at ambient temperature (room) (RT) for one week.

In accordance with the method of the French industry standard NF TT-016 determined the hardness of Perozo, with the results expressed in seconds.

Resistance to methyl ethyl ketone was determined by conducting the test abrasion, while resistance to the action of Skydrol (component based on a complex ester of phosphoric acid, used as a brake fluid in the aircraft) was determined, through immersion of the sample coated at 500 hours at 70°C.

All layers of coatings found excellent water resistance. Properties of the obtained layers of coatings are shown in table 2.

A mixture of complex dispersions of the polyester-polyacrylate polymer and isocyanate components with a ratio of NCO:OH of 1.5:1 without catalyst was diluted to viscosity when sprayed and applied in two layers in the form of a non-pigmented coating on the primer layer blue metallic water-based (Autowave® from Akzo Nobel) on the aluminum substrate. Layers of non-pigmented coating was left to dry for 15 minutes, after which they were dried for 45 minutes at room temperature or at 60°With, resulting in obtaining a dry thickness in the range from 50 to 90 μm. After one week at ambient temperature (room temperature) was measured D.O.I, (clarity) and gloss in accordance with ASTM D-523 at 20°. D.O.I, in the range from 60 to 80 is acceptable, while the shininess on the primer coating at 20°greater than 80 are considered is correspondingly high, while the value of the gloss at 20°greater than 70 is considered acceptable. The results are shown in table 3.
