ARALDITE® LY 3585 / ARADUR® 3835

Fast curing epoxy systems with high thermo-mechanical properties and fatigue resistance ideal for the production of composite leaf springs.

• Resin Transfer Moulding (low and high pressure)
• Wet Compression Moulding

• Mass production of composite parts able to withstand long-term dynamic loading even under severe hot/wet conditions.
• Production of high thickness composite parts

Processing Guidelines

• 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 at an amount of 0.5 – 2% is typically added to the system.
• It may either be mixed as a third component or premixed into the Araldite® LY 3585 immediately prior to use. The amount added depends on internal release agent type and part demolding behavior.

• 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 and Aradur® 3835 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.
• Araldite® LY 3585 resin may sometimes crystallize during storage, forming a cloudy liquid or solid. It may be restored to its original state by heating to 60 - 80°C until a clear liquid is achieved.
