PRINOM ® U 0622

PRINOM ® U 0622

Composition

PRINOM ® U 0622  consists of uncalendered Aramid paper (e.g.  Nomex¹ 411) impregnated with epoxy resin in B-stage.

Application

PRINOM ® U 0622 is used e.g. as interlayer insulation in pole coils of DC-motors.

Properties

PRINOM ® U 0622 is highly compressible and therefore it is suitable to equalize uneven surfaces. After pressing and curing PRINOM ® U 0622 shows good bonding to copper and other metalic surfaces.

Compared with PRINOM ® B 2083 or E20184, PRINOM ® U 0622 insulated coild are easier to clean because the material that protrudes and is not cured under pressure has only weak mechanical properties and breaks easily.

Processing

For gluing together conductors, a pressure of min. 2.5 N/mm² at a temperature of 170°C for one hour is recommended. The conductors must be clean and must not have any grease on the surface.
