FIELD: chemistry.SUBSTANCE: invention relates to elastic repairable thixotropic cold setting compounds with high adhesion strength, which retain improved electrical insulation properties when exposed to high moisture, which are meant for sealing components of electric radio products. The compound contains the following, pts.wt: oligodiene urethane epoxide PDI-ZAK 40-45, trifunctional oligoether epoxide 8-12, monoglycidyl ether of alkyl phenol 8-12, low-molecular weight polyamide resin 7-22, amine 2-5. The compound can be successfully used for moisture protection of components since after exposure to 98% moisture for 30 days, its volume resistivity drops from 1.5-10-9.1·10ohm·cm to 6.0·10ohm·cm, but remains sufficient to ensure electrical insulation of components of electric radio products.EFFECT: obtaining a cold setting compound for moisture protection of components of electric radio products with sufficient working life, which is elastic, thixotropic and repairable.1 tbl |
