Method of sealing narrow, uneven gaps in cylindrical metal compounds with anaerobic compositions based on oligocarbonacrylates

FIELD: machine building. SUBSTANCE: invention relates to means for monitoring and eliminating leaks and is intended for use in engineering. Method for sealing narrow, uneven gaps in cylindrical metal compounds with anaerobic compositions based on oligocarbonacrylates is described, in which, to compact the gaps, the natural shrinkage of the composition is used, which is the property of unsaturated oligomers to shrink in the polymerization by 1–5 %, with the formation of gaps between the walls of the cylindrical surface and the solid polymer, which creates a vacuum in the gaps and facilitates the sucking of the liquid composition present on the surface in the non-polymerized state and its subsequent polymerization in the gap.
