Abstract: The present invention related to a method of manufacturing of a contamination control sheet, the method comprising the steps of: passing a web of support material from a supply roller to a coating station, and applying a coating of polymeric material to one surface of the support material; passing the coated support material through an oven to cure the polymeric material; and passing the coated support material around a cooling roller to a take up roller; characterised in that a nip roller is provided adjacent to the cooling roller so that the coated surface of the support material is pressed onto the cooling roller by the nip roller, and further characterised in that the cooling roller has a surface roughness of 0.2 to 1 Ra.

Abstract: A contamination control mat 10 comprising a support layer 16 which is coated on a top surface with a polymeric contamination control layer 17, wherein the support layer 16 comprises a glass fiber reinforced polymer that is printed on a top surface, the polymeric contamination control layer 17 is transparent or translucent, and the printed surface is visible through the polymeric contamination control layer. This provides a thin yet rigid and stable mat 10 that can also display printed information that is protected from damage. The mat 10 is primarily used to meet contamination control needs.
