Applications & Uses
- Applications
- Recommended Applications
CRYSTIC S15-6 can be used alone or in combination with other polyester resins for the manufacture of flexible products. Impregnating resins particularly isophtalic resins can be flexibilised by addition of CRYSTIC S15-6 without any significant impact on the chemical resistance properties.
- Formulation Guidelines
- CRYSTIC S15-6: 100 parts
- Catalyst M : 1 to 2 parts
- Accelerator E : 1 to 4 parts
Catalyst M is a Méthyl Ethyl Ketone Peroxide at 50% such as the Butanox M 50 from AKZO. Accelerator E is a cobalt octoate at 0.4 % active cobalt. Catalyst and accelerator should not be mixed directly together as they will react with explosive violence.
- Gel Time
The ambient temperature, the quantity and the type of catalyst and accelerator will control the gel time of the resin. The following table shows the gel time in minutes at 20°C of 100 parts of CRYSTIC S15-6

Parts of acc E1 2 4 14 12 Curing should not be carried out at temperatures below 15°C. Resin must reach ambient temperature before application.

Technical Details & Test Data
- Additives
Since certain pigments, fillers or extra styrene may affect properties of CRYSTIC S15-6, their effect should be evaluated before addition to the formulation. The following cold curing formulation is recommended.
Packaging & Availability
- Packaging Type
- Packaging Information
CRYSTIC S15-6 is supplied in 225 kg or 1100 kg containers. Bulk supplies can be delivered by road tanker.
Storage & Handling
- Storage Conditions
CRYSTIC S15-6 when liquid must be kept away from any fire source. It should be stored under cover in the dark in the container in which it is supplied. Storage temperatures should not exceed 20°C. Avoid the proximity of heat and water infiltration risk.
