DELBOND BM 200 54920


General description:

Delbond BM 200 54920 is a thin insulating and bonding product made of woven glass and G-11 epoxy resin with mechanical properties at high temperatures.  

Main characteristics: 

Delbond BM 200 54920 consists of a base layer of woven glass impregnated with a cured epoxy resin which is then laminated with a semi-cured layer of epoxy resin on each side.


Delbond is mainly used for bonding and insulating in one operation, copper bar rotor coils of turbine generators.

Delbond BM 200 is particularly suitable for the insulation of coils end windings but also the straight parts or rotor bars.

The advantage of the high performance DELBOND BM 200 is the high precision assembly application. Their design ensures a low reduction of thickness after the pressing process and enables the use of automatic insertion machines.

This type of Delbond, to the opposite of Delbond BM for example, do not enable to smooth out irregularities on the surface of the coil.

Cure Conditions:

In order to obtain good bonding and optimum results, DELBOND should be cured for 1 hour in a press at a temperature of 160C under a pressure of 150 N/cm.

Storage Conditions:

DELBOND may be used up to 6 months after the date of delivery if kept in its original packaging and at a temperature lower than 25C or 12 months at a temperature of < 4C.


DELBOND is supplied:

- in rolls with a length of approx. 1070 mm

- in tapes of width >= 10+/- 0.2 mm

The length of the roll has to be defined in accordance.

For other dimensions, please consult us.

Please consider that minium quantities might be requested to produce this reference. Please consult us.
