Abstract
In the production of polyurethane parts the use of non- permanent release agents is still inevitable. The regular mold-cleaning of residua of the release agent reduces the efficiency of the production process considerably. This paper describes the development of a permanent plasma- induced release coating with high durability for the series production of PU-parts as a surrogate for conventional non-permanent release agents. Basis of the project is a plasma-polymeric gradient layer with highly crosslinked siloxane-compounds for the mechanical strength of the coating and a high density of methyl groups towards the PU-sided surface for excellent release properties.
