Mix Aradur® 1571 with Accelerator® 1573 to get homogeneous paste, this pre-mix has a long shelf life at RT (min. 2 weeks) The pre-mix Aradur® 1571 / Accelerator 1573 is blended into the Araldite® LZ 3540 and mixed homogeneously just before the prepegging process. 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.
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.
Prepreg Production : Drying conditions by air-circulating oven to get a slightly tacky, flexible prepeg.

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.
