Dolphon® XL-2109 is a 1K resin based on polyester with UV catalysts.
Dolphon® XL-2109 has the following outstanding features:
- very low weight loss on cure
- very low odour
- excellent wetting and penetration properties
- very good bond strength
- fast curing cycles
- medium high viscosity
- good adhesion
Application
Dolphon® XL-2109 can be applied in roll-through and automatic machines.
Recommended cycle for roll-through application:
- Pre-heat the windings to 70-80 °C.
- Bring rapidly the windings to a temperature of 140 °C to gel the resin by Joule-effect.
- Cure 30 min. at 150-160 °C by Joule-effect.
- Complete the cure of the resin on the external part of the unit by UV-rays for 5-10 min.
