Modified nano composite material with high durability
This invention relates to a modified nano composite material with a high durability, multifunctional used for a long time protection of a variety of supports such as metal, wood, construction materials, plastic. The multifunctional composite referred to the invention forms a nano modified polymer matrix which generates in the mono component polyurethane binder, solvent free, nano-structured configurations. This gives the composite material properties, features and superior performance impossible to achieve at a micro scale
This invention refers to an advanced polyfunctional material doped with nanopowder for long lifetime protection of metals and constructional steel Current international research seeks to obtain conventional anticorrosive nano coatings to remove hexavalent chrome (which induces cancer) and zinc phosphate, both of which were declared toxic via environment protection legislation (in the latter case, the prohibition was laid down in the EU Directive 2004/73/EC that has been in force since October 30th, 2005). This substance carries a R-50/53 risk and endangers water life. Research results are not satisfactory
Special process of doping epoxy, polyurethane, silicone polymers with nano powder. The organic matrix will be provide with nano particles by special efficient techniques .Because of the great ratio surface/volume, a great part of a atoms will be considered like surfaces ones or of interface ,consequently to a dependence in high degree of the material of its surface

- watering;
- environmentally friendly (without hexavalent chrome and zinc phosphate);
- thermal shock resistance;
- resistance to atmospheric agents with simultaneous action;
- mechanical shock resistance;
- wear resistance;
- barrier properties;
- wet scrab resistance.
