Abstract
A plugging compound for chemical fastening technology is based on a free-radically polymerizable resin and a free-radical initiator spatially separated therefrom. The plugging compound in question is a self-supporting and storage-stable material which can be inserted in that form directly into a drill-hole.
Claims10
A plugging compound comprising
- A. a free-radically polymerizable vinyl ester or vinyl ester urethane resin,
- B. optionally a methacrylic ester comonomer having a boiling point higher than 120.degree. C.,
- C. a free-radical initiator,
- D. a polymerization accelerant,
- E. a thickener for the resin, and
- F. a filler,
- said plugging compound being in the thickened state and a self-supporting and storage-stable material which can be introduced in that form directly into a drill-hole and said free-radical initiator C or said accelerant D being embedded in the matrix of the other ingredients as a separate phase spatially separated from said matrix.
