Mixing Ratio

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.

Application Information

Araldite LY 3600 CI / Aradur 3600-2 CI is an unfilled, solvent-free, easy-to-handle laminating system. Due to its excellent wetability and long work life, the material produces laminates with good uniformity and is ideal for use on today’s advanced fabrics suitable for wide ranges of industrial composites, aerospace composites. Laminates manufactured using this system also demonstrate excellent stability under a broad range of ambient temperatures. Even better performance properties can be achieved by post curing parts at elevated temperatures.

Processing Recommendation

The temperature where gelation is being carried out should not be higher than necessary. A high gelation temperature induces shrinkage and generates internal stress within the part.

Storage & Handling

Storage Conditions
  • Provided that the components are stored in a dry place in their original, properly closed containers at the above mentioned storage temperatures they will have the shelf lives indicated on the labels.
  • Partly emptied containers should be closed immediately after use.
