- Formulation Guidelines
The following cold curing formulation is recommended:
- CRYSTIC 406COS : 100 parts
- Catalyst M : 1 to 2 parts
- Accelerator E : 4 parts
Catalyst M is a Méthyl Ethyl Kétone Peroxyde at 50% ( MEKP 50. )
Accelerator E is a cobalt octoate with 0,4% active cobalt.
Catalyst and accelerator should not be mixed directly together, as they will react with explosive violence.
- Recommended Applications
CRYSTIC 406COS has been designed especially for the production of filled castings, polyester concrete and composite stone.
- Gel Time
The ambient temperature, the quantity and the type of catalyst will control the gel time of the resin. The typical gel time at 25°C of 100g of resin with 4 ml of Accelerator E and 2ml of catalyst M is 5 minutes.

Technical Details & Test Data
- Additives
Since certain pigments, fillers or extra styrene may the affect properties of CRYSTIC 406COS their effect should be evaluated before addition to the formulation.
- Post Curing
For most applications satisfactory result will be obtained by curing at room temperature (20°C). Some improvement in properties may be obtained by post-curing 16 hours at 40°C after release from the mold.
- Trial Before Use
It is recommended to try the product on a small scale production before the resin is used for long runs.
Packaging & Availability
- Packaging
- Crystic® 406COS is supplied in 225 kg drums, 1100 kg containers or by road tanker.
Storage & Handling
- Storage
- Crystic® 406COS should be stored under cover in the dark in the container in which it is supplied. Recommended storage temperature is 5 - 25°C, and should not exceed 25°C. Storing the resin above 25°C will modify the properties of the product and will significantly reduce the shelf life. If stored outside, keep horizontal to avoid water ingress.
