- Characteristic
PVA Release Agents are a liquid solution of polyvinyl alcohol resin in a mixture of water and industrial methylated spirits sometimes including small quantities of dye and/or matting agent dependent upon the grade. Available clear or blue in both glossy and matt versions. They have been developed to give best results if spray applied but glossy versions can also be applied by sponge or soft brush. PVA Release Agents can be applied over wax polish but the wax polish must be silicone free. Soluble in water and therefore can be washed off molds and moldings with water even when dry. Matt versions are especially useful when producing low gloss finished moldings.
