Typical Cure Cycles

1 h 100°C + 1 h 120°C+ 2 h 180°C for large part
5 min at 150°C or 20 min at 120°C + 2 h 180°C for small / medium part
10 meter / hour in pultrusion
Parts can be demoulded after 1 h 100°C + 1 h 120°C (large part) and 5 min 150°C or 20 min 120°C (small / medium parts) before being free-stand postcured. The optimum cure cycle has to be determined case by case depending on the processing, the economic and mechanical requirements. Not postcuring might be considered in some applications.

Processing Guidelines

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.

Safety & Health

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.

Handling Precautions

Personal hygiene - Safety precautions at workplace

protective clothing yes
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
