METHOD FOR APPLYING COATINGS Russian patent published in 2004 - IPC

FIELD: processes for applying liquid or other fluid materials onto surfaces, for example protection coating of metallic surfaces, polymeric roof materials and so on. SUBSTANCE: method comprises step of preparing surface; preliminary preparation of components and their successive application onto surfaces to be coated. Novelty is forced feed of components into reaction chamber for agitating them by means of air and realizing mutual reaction of fed components. Then components are discharged from nozzle by action of pressure P. Value of pressure Pc created by means of jet at applying working mixture onto surface is selected in range 1≤(α+β+γ₁+γ₂+...+γ_n)P_c+P_atm≤18,6, where Patm - atmospheric pressure; α - empiric coefficient depending upon properties of worked surface (material type, its roughness, porosity and so on), β - empiric coefficient taking into account outer influence (temperature, wind speed, moisture degree and so on), γ_c -empiric coefficient characterizing state of n-component of coating and depending upon properties of applied components (viscosity, fluidity, density and so on). Forced penetration of mixture of two or several components reacted one with another into micro irregularities and(or) pores of worked surface enhanced characteristics of "worked surface - applied coating" interface. EFFECT: enhanced quality of applied coating.
