ARALDITE® LY 3585 / ARADUR® 917-1 / ACCELERATOR DY 080

• Anhydride-cured, low-viscosity standard matrix system with extremely long pot life.
• The reactivity of the system is adjustable by variation of the accelerator content.
• The system is easy to process, has good fibre impregnation properties and exhibits excellent mechanical, dynamic and thermal properties.
• It has an excellent chemical resistance especially to acids at temperatures up to 80 °C.

• Pultrusion

• 2 - 4 h at 140°C
• 1h at 190°C

• 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. Internal release agent with an amount of 4 - 6 pbw is typically added to the system. It can either be mixed in as a 4th component or premixed into the Araldite® LY 3585.
• The added amount depends on internal release agent type and part demolding behavior. Internal release agent used in this TDS is Chemlease IC 25 from Chemtrend.

Note

• 2 - 4 h at 140°C

Properties of The Cured, Neat Formulation

The figures given are for pultruded laminate samples comprising a 4 mm profile of 50 K carbon roving from SGL Group (SGL CT50-4.0/240-E100), fibre volume fraction 63-65 %. (Die length 1m with 3 heating zones (155°C/195°C/195°C).

Unless otherwise stated, the processing schedule for the samples tested was gelation for 4 hours at 80 °C and post-cured for 8 hours at 140 °C.

• 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.

• Provided that Araldite® LY 3585, Aradur 917-1 and Accelerator DY 080 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. Because Aradur® 917-1 is sensitive to moisture, storage containers should be ventilated with dry air only.
• Araldite® LY 3585 which has crystallized and looks cloudy can be restored to its original state by heating to 60 - 80 °C.
