SynChem – Resins & Varnishes Dolphon® XL-2102 1K Resin
Dolphon® XL-2102 is a transparent, low emission, 1K resin based on polyester.
Dolphon® XL -2102 is characterised by the following properties:
- Excellent wetting properties
- Approved for railway applications acc. EN 45545-2: HL3 for R22 and R23
- Low weight loss on cure
- Very low odour
- Relatively fast cure cycles
Application
Dolphon® XL-2102 is a proven resin for impregnating stators, rotors, transformers, traction coils and inductances.
Standards
- UL-approved Class H (180 °C), File OBOR2.E317427 and OBJS2.E317429
- UL-System-approved 130 - 220 °C
- EN 45545-2: HL3 for R22 and R23
UL-approved with magnet wire temperature class according to UL 1446:
| Magnet wire | Twisted pairs | Helical coils |
| MW 16-C | 220 °C | - |
| MW 28-C | 130 °C | - |
| MW 35-C | 180 °C | 200 °C |
Delivery forms
Dolphon® XL-2102 is delivered in 25 kg disposable containers, 230 kg barrels and 1000 kg containers.
Storage
Dolphon® XL -2102 can be stored for 18 months at room temperature in a sealed container (max. 30 °C). The 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.
Hardening
The curing time commences once the object temperature
has been reached.
Typical curing time:
at 150 °C - 1 h*
at 130 °C - 3-4 h*
at 120 °C - 5-7 h*
*(Full curing is measured by DSC. The time must be taken after units reach the baking temperature). For objects having to endure high mechanical or chemical stress during service, longer curing times are recommended.
Best results will be achieved at:
150 °C - 2.5 h
160 °C - 2 h
170 °C - 75 min.
Protection
Cured Dolphon® XL-2102 is biologically inactive and safe to health. Always refer to the safety data sheet and implement protective measures when processing the liquid dip resin.
Cleaning
Since the cured 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.
Processing
Exemplary impregnating process suggestion:
1. Preheat the units at 50-60 °C (max.)
2. Dip into the resin for 30-60 min.
3. Drain for 1 h min.
4. Bake 1 h at 150 °C* (see "Curing")
For the VPI application the cycle must be set for each type of machines. Feel free to contact us.
