METHOD OF OBTAINING LACQUER COATING MAINLY ON ARROW-SHAPED BULLETS Russian patent published in 2012 - IPC C09D5/44 C09D119/00 F42B5/295 

FIELD: chemistry.

SUBSTANCE: method involves cathodic electrodeposition from a water-base lacquer composition containing 60-70% solution in a mixture of ethylglycoacetate and butanol epoxyamino-rubber adduct modified with malamine-formaldehyde resin K-421-02, an organic acid and distilled water, and hardening the coating. The lacquer composition additionally contains 75-85% solution in toluene bis(dicresoxy-phosphine-oxy)dibutoxy titanium, with the following ratio of components in wt %: 60-70% solution in a mixture of ethylglycol acetate and butanol epoxyamino-rubber adduct, modified with melamine-formaldehyde resin K-421-02 - 1.6-11.0; 75-85% solution in toluene bis(dicresoxy-phosphine-oxy)dibutoxy titanium 0.008-1.1; organic acid 0.008-1.1; distilled water - the rest. Electrodeposition is carried out at voltage 60-200 V for 3-60 s.

EFFECT: designing a method of obtaining coatings mainly on arrow-shaped bullets, having high corrosion resistance in NaCl solution and enabling complete sealing of cartridges with anaerobic sealants.
