PVA is a special formula release agent for the fiberglass industry. This product is designed to prevent lamination of the product to the mould. Preventing the mechanical or chemical bonding of the molded material to the surface of the mould. PVA is a film-forming solution, which places a positive barrier between the mould and the product or component. PVA may be used on smooth, hard surfaces or on other surfaces in tandem with wax style mould releases such as J-WAX. PVA is best used in conjunction with wax style release agents as an extra or additional barrier; particularly in the moulding of small, intricate or challenging shapes. PVA should also be used together with waxes on poor surface moulds and on absorbent surface moulds.
