Delivery format

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 cold
place and protected against direct sunlight, UV radiation
and sources of heat.


Always observe general rules and regulations.


Processing


Exemplary impregnating process suggestion:

1. Pre-heat the object to approx. 105-120 °C.
2. Trickle the resin on the unit, keeping it in slow rotation
3. Cure at 150-160 °C for 20-30 min.

Vacuum (pressure) impregnating is possible.

Hardening


Proposed curing time for trickle impregnation:

150-160 °C - 20 to 30 min.

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.
