ABSTRACT:
An anaerobic liquid acrylate sealant composition contains short portions of one or more types of fibre, particularly aramid fibre pulp, as a filler. A particulate filler such as fumed silica and/or micronized polyethylene may also be present. The composition suitably is based on a high proportion of monofunctional acrylate ester monomer, and a polyacrylate plasticiser. The composition is used for sealing joints in pipework where it is desired to seal the joint almost immediately but to allow adjustment of the joint for at least 24 hours.
