Product Features

Easy-to-handle laminating system for the production of advanced composites using the wet lay-up process.
The system exhibits an excellent impregnation behaviour due to its low viscosity.
As a consequence of its high reactivity short Cycle times can be realized even though the pot life is long.
The system has superior adhesion properties.

Properties

Notes

Gel Time : The values shown are for small amounts of pure resin/hardener mix. 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

10 min 110 °C

8 min 120 °C

60 min 80 °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

We recommend that the components are weighed with an accurate balance to prevent mixing inaccuracies which can affect the properties of the matrix system. The components should be mixed thoroughly to ensure homogeneity. It is important that the side and the bottom of the vessel are incorporated into the mixing process. When processing large quantities of mixture the pot life will decrease due to exothermic reaction. It is advisable to divide large mixes into several 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 solvents
Disposal of spillage	Soak up with sawdust or cotton waste and deposit in plastic-lined bin
Ventilation of workshop	Renew air 3 to 5 times an hour
Ventilation of workplaces	Exhaust fans. Operatives should avoid inhaling vapours

First 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.

Storage & Handling

Storage Conditions

Provided that the products described above are stored in a dry place in their original, properly closed containers at the above mentioned storage temperatures they will have the shelf lives indicated on the labels.
