The present  research is devoted to physical-chemical, technological  aspects and material authority of  order to produce nanostructured paint and vanish composites.

In capacity of research objects are chosen stove paint and varnish materials  such as semi-manufactured vanish ML-0136, enamel ML-12 black produced by Joint Stock Company  “Lakokraska” and metallic nanomaterial.

Film-forming compositions are obtained by bringing in vanish ML-0136 and enamel ML-12 of calculated amount of nanofiller  which should be crushed in ball grinder before and kneaded. Solutions are poured on clean and degreased surfaces from steel, tin ang soda-lime glass. Obtained compositions are hardened in the oven  at elevated temperature  (130-140 °C) within 30 minutes till the insiccation extent 3.

From analysis of physical, mechanical and adhesion coating characteristics it follows that nanofillers make it possible to improve hardness of coating  from 0.35  to 0.42 standard units. Investigated nanofiller show it’s the greatest efficiency if it is brought in small amount  (0.5 %  content  to solid residual mass ). In this connection  it is observed optimal values of  physical, mechanical and adhesion perfomance.

Compositions on basis of  enamel ML-12 black are obtained similarly. Investigation showed  that metallic nanofiller  have an influence on coating properties based on enamel ML -12.  Hardness of coatings, bending strength and adhesion depend on content of nanosize particles. Optimal value of concentration is 0,5 %. If  modifier content is more than 0,5%, coating elasticity becomes worse.

Consequently it is induced law of influence of superdispersed filler content on breaking point and adhesion durability of investigated film-forming composites based on melamine-formaldehyde oligomers. It is specified optimal concentration of nanofiller when maximum breaking point  (more than 100 centimetres) and maximum adhesion durability of coating to steel (0 point) can be reached.
