Abstract
A method of forming an impact-resistant, moisture impermeable coating on the surface of an object, such as a pipe, comprises heating the object to a temperature above which a thermosetting resin applied to the heated surface will fuse, so that the resin forms a continuous layer. Before the layer of resin has gelled, a second layer consisting of a finely divided particulate mixture of the resin and a solid such as glass fiber or mica is applied over the first layer. The two layers are fused together to form a homogeneous resin covering with one layer reinforced by the above solid. The resin coating is then cured and the object allowed to cool. An apparatus for carrying out the method is also described.
