Typical Cure Cycles
Stage Condition Gelation 2 – 4 h at 80 °C 1 – 3 h at 90 °C Post-Cure 4 – 8 h at 120 °C
2 – 8 h at 140 °C
2 – 8 h at 160 °C
Cure temperatures in excess of about 130 °C cause brown discolouration but do not impair the properties of the product.

Technical Details & Test Data
- Mixing Ratio
The two hardeners should be premixed and then added to the resin. The components should be mixed thoroughly to ensure homogeneity.
- Processing Recommendation
To simplify the mixing process the resin can be preheated to about 30 °C to 50 °C before adding the cold hardener. Hardener and accelerator can be premixed, thus allowing the use of two component mixing/metering equipment. The mix of hardener and accelerator has a shelf life of several days. The processing of the system at elevated temperatures of 30 °C to 40 °C shows the best results. The gelation temperature should not be higher than absolutely necessary. A high gelation temperature induces high shrinkage and generates internal stresses.

Safety & Health
- Handling Precautions
First Aid
In case of contact :- Ingestion : If swallowed, immediately give at least 3-4 glasses of water, but do not induce vomiting. If vomiting occurs, give fluids again. Do not give anything by mouth to an unconscious or convulsing person. Get immediate medical attention. Have a physician determine whether vomiting or stomach evacuation is necessary.
- Skin : Under a safety shower, immediately remove contaminated clothing and shoes. Wash affected areas thoroughly with large amounts of water, and soap if available, for at least 15 minutes. Get immediate medical attention. Discard or decontaminate clothing before re-use and destroy contaminated shoes.
- Inhalation : Remove from area to fresh air. If not breathing, give artificial respiration. Get immediate medical attention. If breathing is difficult, transport to medical care and, if available, give supplemental oxygen.
- Eyes : Immediately flush eyes for at least 15 minutes with running water. Hold eyelids apart to ensure rinsing of the entire eye surface and lids with water. If physician is not available, flush for an additional 15 minutes. Get immediate medical attention.
