FIELD: methods or devices for cementing, plugging holes, crevices or the like.
SUBSTANCE: plugging composition comprises silicone composition, water, curing agent, namely hydrochloric acid, and modifier. The silicone composition is silicone fluid, the modifier is stock-tank oil. All above components are taken in the following amounts (% by weight): silicone fluid - 75.8-92.5, hydrochloric acid - 0.4-2.4, water - 0-16.7, stock-tank oil - 1.7-5.1.
EFFECT: increased plugging capacity along with reduced expensive silicone composition consumption.
