Based on high-melting waxes and aliphatic hydrocarbons, dries quickly.
Specifically for epoxy, polyurethane moulds and patterns. If the surface is porous, it must first be treated with a sealer such as PVA. PVA is not necessary on non-absorbent surfaces such as metal, glass or ceramic resin. Brush on 2-3 coats of PST-4, waiting 2-3 minutes after each coat to allow it to dry. The coat can be polished with a soft cloth. A glossy finish is achieved by polishing before the coat is dry.
The product is flammable.
Please note: Always mix the product thoroughly before use to homogenise waxes and solvents.
