METHOD FOR PROTECTION OF ROOF SURFACES AND SEPARATE PARTS OF TRANSPORT AND MILITARY EQUIPMENT AND SPECIAL-PURPOSE EQUIPMENT (EMBODIMENTS) Russian patent published in 2025 - IPC B05D7/24 B05D7/14 B05D7/04 B05D7/06 C09D175/02 C08G18/32 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to methods of applying polymer coatings by spraying for protection of roof surface and separate parts of transport and military equipment of special purpose. Disclosed is gumming a surface with polymeric two-component or three-component compositions. Two-component composition is obtained from a reaction product of component A, which is an amine-containing composition, and component B, which is an isocyanate-containing composition. Three-component composition further includes component C, which is a polyester-containing composition. Coating components application is carried out by the heating hoses through the mixing spray gun, wherein the coating is carried out in the following order: applying the coating to the welds and hard-to-reach places; application of 1–3 coating layers on entire surface with control of thickness; sputtering with composition by spraying composition in horizontal plane, after which, in the process of settling on the surface, it partially dries, forming a rough surface.

EFFECT: invention provides anti-skid coating to increase safety of maintenance personnel.
