Abstract
A composition for sealing joints, penetrations and other leaks in particular in the construction field, including at least one ethylenically unsaturated, radically polymerizable water-soluble compound, at least one radical initiator, water and at least one corrosion inhibitor including at least one phosphate. The corresponding composition has a corrosion-inhibiting effect with respect to metal.
Claims16
A composition for sealing joints and penetrations, comprising:
- a) at least one ethylenically unsaturated, free-radically polymerizable water-soluble compound,
- b) at least one free-radical initiator,
- c) water, and
- d) at least one corrosion inhibitor comprising at least one phosphate, wherein:
- the at least one ethylenically unsaturated, free-radically polymerizable water-soluble compound has a proportion by weight of 25 to 55 percent by weight, based on the total weight of the composition,
- the at least one phosphate comprises an alkali metal or alkaline earth metal salt of orthophosphoric acid, or a mixture thereof, and
- a weight ratio of the at least one ethylenically unsaturated, free-radically polymerizable water-soluble compound to water is in a range of from 0.1:1 to 3:1.
