ABSTRACT:
The method of the invention for co-reactive slot die extrusion coating of elongated tubular articles, such as pipes, comprises the steps of extruding a two-component thermosetting material through a slot die that is comprised of low friction material and so configured as to permit the slot die to be rapidly opened for purposes of peeling gelled material from the die by hand. The method provides for substantially increased coverage rates and the use of interchangeable and reusable slot dies. In a preferred method, the extrusion step campuses the use of a slot die comprised of two blocks comprised of an acetal resin, and the blocks are clamped together and can be quickly unclamped to permit convenient removal of gelled thermoset material.
