COMPOSITION FOR CONCRETE PROTECTIVE COATING Russian patent published in 2012 - IPC C04B41/63 C04B26/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a composition for concrete protective coating and can be used in protecting freshly laid concrete of roads and aerodromes from dehydration, as well as in hydraulic engineering and monolithic building construction. The composition for concrete protective coating contains latex, a paraffin component, C₁₃ fatty acid, an alkaline component, a surfactant - OP-7 or OP-10, a thickener and water. The alkaline component is selected from triethanol amine and the paraffin component is paraffin wax, with the following ratio of components, wt %: latex 2-25, paraffin wax 3-25, C₁₃ fatty acid 0.5-3,0, triethanol amine 0.3-5.0, said surfactant 0.1-0.5, thickener 0.1-0.5, water - the balance.

EFFECT: preparation of a composition with optimum viscosity which does not change during prolonged storage.
