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.
Cleaning
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 impregnating plants, especially cleaning, must be carried out according to operational requirements. Always refer to the user manual of the plant.
Processing
Exemplary impregnating process suggestion:
Trickle-process
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
Roll-Through-process
1. Pre-heat the object to 80-90 °C
2. Roll the object in the resin
3. Bring rapidly the object to a temperature of 140 °C to gel the resin
4. Bake for about 30 min at 140-150 °C
Pre-heating is not necessary if the object is dry. Times apply when the object temperature has been reached.
