Abstract
Process for the impregnation of asbestos or other fibrous material, comprising, as a first step, impregnating, with the application of pressure, the material with a polymeric resin binder to substantially saturate the material with binder and, as a second step, applying a polymeric resin compound comprising a polymeric resin and a filler. The process of the invention substantially prevents the escape of minute fibers of asbestos into the atmosphere, and so reduces the health hazard associated with asbestos.
Claims10
A process for the in situ impregnation of asbestos material, comprising a first step of substantially saturating, with the application of pressure, the said material with a binder being a polymeric resin, and a second step of applying a polymeric resin compound comprising a polymeric resin and a filler.
A process as claimed in any one of the proceeding claims wherein the resin applied in the second stage is porous to water vapour but not dust.
A process for impregnating asbestos material, said process comprising the steps of:
- (a) applying a polymeric resin binder to said asbestos material, with application of pressure to said asbestos material, to give a treated material which is substantially saturated with said polymeric resin binder, said application of pressure assisting impregnation of said binder into said material;
- and
- (b) applying to said treated material a coating of a polymeric resin material comprising a polymeric resin and a filler.
