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
