- Formulation Guidelines
The following formulation is recommended in the case of curing at workshop temperature:
CRYSTIC 5008 ST 100 parts Trigonox 44 B 1 to 2 parts Accelerator NL 49P 1 to 3 parts Trigonox 44 B is an Acetyl acetone peroxide from AKZO. Accelerator NL 49P is an accelerator with 1% of Cobalt also from AKZO.
- Applications
CRYSTIC 5008 ST is recommended for the manufacture of moldings for land transport and industrial applications.
- Gel Time
CRYSTIC 5008 ST should be allowed to attain workshop temperature (15ºC - 20ºC) before use. It only requires the addition of catalyst to start the curing reaction. The recommended catalyst system is Accelerator NL49P and Trigonox 44 B. Geltime at 40°C for 100 parts of resin catalysed with 2 ml of NL49 P and 1.5 ml of Trigonox 44 B is of 5.5 – 7.5 min.

Technical Details & Test Data
- Additives
The addition of fillers or pigments can adversely affect the vacuum infusion process and also the properties of the cured laminate. Please contact Scott Bader’s Technical Service Department before using additives.
- Post-cuisson
CRYSTIC 5008 ST should be allowed to attain workshop temperature (15ºC - 20ºC) before use. It only requires the addition of catalyst to start the curing reaction. The recommended catalyst system is Accelerator NL49P and Trigonox 44 B. Geltime at 40°C for 100 parts of resin catalyzed with 2 ml of NL49 P and 1.5 ml of Trigonox 44 B is of 5.5 – 7.5 min.
Packaging & Availability
- Packaging Type
- Packaging
- Crystic® 5008 ST is available 225 kg drums, 1100 kg containers. Bulk supplies can be delivered by road tanker.
- Variants
CRYSTIC 5008 ST is also available in a shorter gel time version under reference CRYSTIC 5008 LGT.
Storage & Handling
- Storage
- Crystic® 5008 ST should be stored in the dark in suitable, closed containers. It is recommended that the storage temperature should be less than 20°C where practical, but should not exceed 30°C. Ideally, containers should be opened only immediately prior to use. Where they have to be stored outside, it is recommended that they are kept in a horizontal position to avoid the possible ingress of water.
