A STUDY ON PREPARATION OF PROTECTIVE PRINTED CIRCUIT BOARD COATING BASED ON EPOXY RESIN MODIFIED BY LIQUID POLYSULFIDE RUBBER
This paper presents some results in studying and producing a coating to protect printed circuit board from tropical environmental impact. We have tested the protective ability of the coating based on epoxy resin ED-20 and low-molecular weight polyamide resin L-20 modified by liquid polysulfide rubber NVB-2. The testing data has shown that the coating has high mechanical, environmental and electrical durability.
