摘要： A process for simultaneously batch-coating a number of electric components having radial connections wires extending in approximately parallel relation from the element to be covered utilizes a plate having a hole pattern therein for receiving the wires to retain the elements during coating. A synthetic foil is first placed over the plate and the wires are forced through the foil into the holes. A grid having openings therein formed by perpendicular walls for surrounding the elements is placed over the plate for use as a casting mold. A casting resin is deposited over the grid in excess quantity, and is then smoothed by moving a doctor over the grid. After the resin has hardened, the grid is removed and the individual elements, with the resin adhering to the synthetic foil, are separated.

摘要： A curable composition, especially adaptable for use as insulation for wire and cable, comprising an ethylene-containing polymeric member, a curing agent, and a silicone fluid having a viscosity not greater than about 100 centistokes at 25.degree.C. A filler such as carbon black or a mineral filler may be incorporated into the system.
