Abstract:
A process for providing one or more thermoset polymeric materials onto an object is disclosed wherein said process comprises at least the following steps: Providing a polymeric composition having a viscosity >10 Pa.s at room temperature comprising at least one cross-linkable polymeric material; and then Optionally heating the polymeric composition to achieve a liquid cross-linkable polymeric composition having a viscosity below 4 Pa.s, and then Depositing the polymeric composition onto an object using a spray, swirl or extrusion nozzle and wherein the deposition is performed while the object and/or nozzle are moving to create an object at least partly coated with said polymeric composition; and then Optionally cooling down the at least partly coated object to room temperature, and then Optionally repeating one of foregoing steps, and then Applying a cross-linking treatment selected from radical curing, UV curing and/or heat treatment in order to convert the cross-linkable polymeric material(s) into thermoset polymeric material(s).
