Dolphon® XL-2102 OPT 1K Resin
|
Description
|
Dolphon® XL-2102 OPT is a transparent, low emission,
1K resin based on polyester.
|
|
Properties
|
Dolphon® XL -2102 OPT is characterised by the following
properties when in a liquid state:
- low viscosity
- high reactivity
- low odour, low emissions
- no MAK value
- good storage stability
- very short curing time at 150 °C
- excellent penetration in the winding
Cured Dolphon® XL-2102 OPT is a material with the
following exceptional properties:
- very good bond strength combined with flexibility
- high dynamic load capacity
|
|
Application
|
Dolphon® XL-2102 OPT is a trickle resin which due to its
storage stability can also be used as a fast curing dip
resin. It is a proven product for the trickle impregnation of
sophisticated electric motor rotors and stators, as well as
larger objects, such as large-scale coils. It also provides
numerous advantages when impregnating small
transformers during full capacity production.

Dolphon® XL-2102 OPT is delivered in 25 kg disposable
containers or in 230 kg barrels.
|
|
Storage
|
Dolphon® XL -2102 OPT can be stored for 18 months at
room temperature in a sealed container (max. 30 °C).
The trickle and dip resin must be stored in a suitable
place and protected against direct sunlight, UV radiation
and sources of heat.
Always observe general rules and regulations.
The storage life of the dip resin can be extended
indefinitely by adding fresh resin during processing.
|
|
Processing
|
Due to its low viscosity, low emission Dolphon® XL-2102
OPT can be processed in existing trickle plants without
heated pipes and, in general, without process changes.
Exemplary impregnating process suggestion:
1. Pre-heat the object to approx. 120 °C.
2. Trickle impregnate the rotating, inclined object
for 4 min.
3. Cure at 150 °C for 0.5 to 1 hour (measured once the
object temperature has been reached) in the closed
oven.
4. Optional slightly forced cooling in the exhaust air flow
Vacuum (pressure) impregnating is possible.
|
|
Hardening
|
Curing occurs via the Joule heat or in the closed oven.
During curing processes in the drying oven, the fresh air
supply should be reduced to the lowest possible level for
safety reasons.
The curing time commences once the object temperature
has been reached.
Typical curing times:
at 150 °C 0.5 - 1 h
at 140 °C 1 - 2 h
at 130 °C 2 - 4 h
|
|
Cleaning the equipment
|
Since the cured trickle and dip resin is practically
insoluble, the tools have to be cleaned as soon as
possible with a suitable solvent. Maintenance and care of
impregnating plants, especially cleaning, must be carried
out according to operational requirements. Always refer to
the user manual of the plant.
|
|
Protective measures
|
Cured Dolphon® XL -2102 OPT is biologically inactive and
safe to health. Always refer to the safety data sheet and
implement protective measures when processing the
liquid trickle and dip resin.
