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
of workshop : Renew air 3 to 5 times an hour
of workplaces : Exhaust fans. Operatives should avoid inhaling
vapours

Storage & Handling

Storage Conditions

Provided that Araldite® LY 1556 or Aradur® 22962 are stored in a dry place in their original, properly closed containers at the storage temperatures mentioned in the MSDS they will have the shelf lives indicated on the labels. Partly emptied containers should be closed immediately after use. Aradur® 22962 can crystallize at low temperature and adverse conditions. This crystallization effect is reversible if the material is heated up above 30 - 40 °C for a certain time. There is no change in chemical composition or suitability as hardener for epoxy resins.
