Features & Benefits
- Ready-to-Use Product Features
- Product Features
- Low viscosity, easy impregnation of reinforcement materials.
- Long potlife (2 hours for 100 ml at ambient), ample processing time allows production of big objects.
- High temperature resistance (Glass Transition Temperature) after ambient Cure: 60 °C, after post-Cure at 100:120 °C.
- Excellent mechanical and dynamic properties after ambient Cure with potential for even higher properties after post-Cure at elevated temperatures.
- Also laminates show outstanding mechanical and dynamic properties.
- Adequate skin protection is indispensable.

Gel Time : The values shown are for small amounts of pure resin/hardener mix. In practice, fibre content and laminate thickness may modify the gel time to a very significant extent. In composite structures the gel time can differ significantly from the given values depending on the fibre content and the laminate thickness.
Processing Properties :
Typical Cure Cycles 1 day 23 °C + 4 h 100 °C 1 day 23 °C + 15 h 50 °C The optimum Cure Cycle has to be determined case by case, depending on the processing and the economic requirements.

Technical Details & Test Data
- Mixing Ratio
The components must be weighed accurately and mixed thoroughly to obtain optimal properties. The sides and bottom of mixing vessels must be included in the mixing process. Large mix quantities will show considerable exotherm, leading to short potlives. Preferably mix smaller quantities or divide large mixes into smaller containers.

Safety & Health
- Handling Precautions
Personal hygiene Safety precautions at workplace protective clothing overalls gloves essential arm protectors recommended when skin contact likely goggles/safety glasses yes Skin protection before starting work Apply barrier cream to exposed skin after washing Apply barrier or nourishing cream Cleansing of contaminated skin Dab off with absorbent paper, wash with warm water
and alkali-free soap, then dry with disposable towels.
Do not use solventsDisposal of spillage Soak up with sawdust or cotton waste and deposit in
plastic-lined binVentilation of workshop Renew air 3 to 5 times an hour Ventilation of workplaces Exhaust fans. Operatives should avoid inhaling
vapoursFirst Aid : Contamination of the eyes by resin, hardener or mix should be treated immediately by flushing with clean, running water for 10 to 15 minutes. A doctor should then be consulted. Material smeared or splashed on the skin should be dabbed off, and the contaminated area then washed and treated with a cleansing cream (see above). A doctor should be consulted in the event of severe irritation or burns. Contaminated clothing should be changed immediately. Anyone taken ill after inhaling vapours should be moved out of doors immediately. In all cases of doubt call for medical assistance.
