- Mix ARADUR® 1571 with ACCELERATOR 1573 to get homogeneous paste, this premix has a long shelf life at RT (min. 2 weeks). Preheat the resin LY 5150 to 40-50°C. The premix ARADUR® 1571/ACCELERATOR 1573 is then blended into the resin ARALDITE LY 5150. Add the HARDENER XB 3403 and mix homogeneously just before the prepregging process.The prepreg tackiness can be adjusted by the amount of the HARDENER XB 3403.
- 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 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.
