Store the components in a dry place at 18-25°C, in tightly sealed original containers.
Under these conditions, the shelf life will correspond to the expiry date stated on the
label. After this date, the product may be processed only after reanalysis. Partly emptied
containers should be tightly closed immediately after use.
For information on waste disposal and hazardous products of decomposition in the event
of a fire, refer to the Material Safety Data Sheets (MSDS) for these particular products.

Processing
The resin component should be stirred and homogenized in the original container before
use.
The casting mix is best prepared by heating the resin up to 40-50°C before stirring in the
hardener. Brief degassing of the mix under 5-10 mbar vacuum improves the mixture
homogeneity and enhances the dielectric properties of the castings.
Araldite CY 1300 GB and Hardener HY 2918 are alternatives to Araldite F and Hardener
HY 905 respectively.

recommended when skin contact likely
yes
no
Skin protection
before starting work
after washing
Apply barrier cream to exposed skin
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
Clean shop requirements
Cover workbenches, etc. with light coloured
paper. Use disposable beakers, etc.
Disposal of spillage
Soak up with sawdust or cotton waste and
deposit in plastic-lined bin
Ventilation:
of workshop
of workplace
Renew air 3 to 5 times an hour
Exhaust fans. Operatives should avoid inhaling
vapours.
First Aid
Contamination of the eyes by resin, hardener or casting 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.
