Flexible Laminates

PRINOM ® U 0622


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


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


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.


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.
