Flexi-coat Release is a water based release, made from an emulsion of silicone oils and resins. This release may be brushed or sprayed into a polyurethane mould before casting concrete or plaster. When used with a spray applicator, it is an economical alternative to aerosol release agents. The use of a soft brush to distribute the release agent evenly may improve results. It works best when allowed to dry; therefore, a thin application is preferred to accelerate this process.
Primary use is for polyurethane and latex moulds when casting cement based products.
As with other releases containing silicone, castings may need washing before applying finishes. Since Flexi-Coat Release Agent is water-based, it does not affect the dimensions of cured rubber moulds as much as releases that contain solvents.
