Mould sealer

While the mold might be cleaned, no matter the mold structure (epoxy, polyester, tooling board, aluminum), there will always be a micro porosity which will have a direct impact on the mold quality and release properties. Mold Sealers are specific to the composites industry and are an integral part of the Primer/Sealer/Release Agent combination ("the release system"). When a “release system” approach is used within composite molding applications there are notable benefits in the areas of mold release ease, finish quality and the number of releases per application of the release agent. When the sealer is matched with a chosen mold release agent, they provide excellent preparation of the mold surface to leverage the qualities of the release agent in order to provide additional benefits and value.
