SELECTIVELY REMOVABLE INTERMEDIATE COATINGS AND METHOD OF USING SAID COATINGS Russian patent published in 2010 - IPC C09D177/00 B32B27/34 B32B27/38 B32B27/40 

FIELD: chemistry.

SUBSTANCE: invention relates to selectively removable intermediate coating compositions, containing at least one polyamide with a terminal amino group, in which average molecular weight of the polyamide with the terminal amino group ranges from 500 Da to 100000 Da. The invention also relates to a multilayer coat containing a first coat (basic coat); a second coat (outer coat); an intermediate coat between the first and second coats, in which the intermediate coat contains at least one polyamide with a terminal amino group, which is used to coat surfaces of aircraft and spacecraft.

EFFECT: obtaining a coating composition for facilitating selective removal of the outer and intermediate coats by washing off without removing the basic coat.
