The Hand Lay-Up process utilizes release sheets (peel ply release sheets) made by out of Teflon® Glass Fabric to assist in the release of the cured product from the mold. The flexibility of the fabric allows it to conform easily to the mold and the coating allows it to be easily and cleanly removed. In some cases, our porous bleeder cloth is required to allow the resin to flow through the fabric. Other applications require our fabric to contain the resin. Resins are applied in either liquid or semi-liquid states.
