Applications & Uses

Composites Processing Methods
Mixing Ratio

The hardener and accelerator can be premixed to allow the use of two-component mixing/dosing equipment. 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.

Product Properties

Araldite® LY 564 with Aradur® 917 and Accelerator 960-1 exhibits a low mix viscosity at room temperature in combination with long pot life. Nevertheless very short Cure Cycles can be achieved at cur temperatures above 120°C for an economical production. The system shows good fiber impregnation properties and is easy to process. The Cured system has excellent mechanical properties.

Safety & Health

Handling Precautions

Danger ! Materials are corrosive and cause severe eye and skin irritation. May cause sensitization.

  • Avoid contact with eyes.
  • Avoid breathing dust.
  • Avoid contact with skin.
  • When poured, resin can generate static electricity sparks which can ignite flammable vapors or dusts.
  • Use with good ventilation.


First Aid


In case of contact :

  • Eyes : Promptly flush with large amounts of water. Get immediate medical attention.
  • Skin : Promptly wash with mild soap and water.
  • Inhalation : Remove to fresh air. Give oxygen if breathing is difficult.
  • Ingestion : If conscious, give plenty of water. Get immediate medical attention.

Storage & Handling

Storage Conditions

Store at 40 - 104°F. Partially used containers should be immediately closed after use and stored in a dry environment. Aradur® 917 is sensitive to moisture, storage containers should be ventilated with dry air only
