FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, is used for sealing electrical products and radioelectronic equipment and serves for their protection against negative effect of air atmosphere and/or negative effect of various factors when using electrical equipment under ground. Polyurethane compound of cold curing is a two-component system consisting of Component "A" – polyol component and Component "B" – isocyanate component, wherein Component "A" consists of fatty carboxylic acids triglyceride (FCAT) with ricinolium content of not less than 80–90 %, polyether with molar weight of 300–500, filler, fire retardants, dehydrator, deaerator, and Component "B" is polymerized methylene diphenyl diisocyanate (PIC).
EFFECT: creation of polyurethane atmosphere-resistant compound of cold hardening with increased manufacturability.
