Signs and other artwork are made with a clear facing layer of polyester resin protecting one or more coloured pattern layers. The pattern layers are applied by silk screening after the facing layer has cured to at least a tack free condition. At the rear is applied a background layer of polyester resin and a stiff glass fibre backing layer.
摘要:
An inexpensive conductive mold designed primarily for lowproduction output is provided. The mold includes an insulating supporting wall having an exposed surface covered with a conductive gel coat comprising a tooling base resin and an electrically conductive filler of a carbonaceous material in particle form, particles being in contact to form a conductive network throughout the gel coat. Ground conductors are molded into the supporting wall and are in contact with the conductive gel coat, the conductors being sufficient in number that the conductive gel coat has a resistance of not more than about two thousand megohms from any point on the mold surface to the nearest conductor.
