- Recommended Applications
CRYSTIC R 115 PA can be used by hand lay up or by spray application for the production of most glass reinforced laminates.
- Formulation Guidelines
The following cold curing formulation is recommended:
- CRYSTIC R 115 PA : 100 parts
- Catalyseur M : 1 to 2 parts
Catalyst M is a Méthyl Ethyl Kétone Peroxyde at 50% such as the Butanox M 50 from AKZO.
- Gel Time
The ambient temperature, the quantity and the type of catalyst will control the gel time of the resin. Curing should not be carried out at temperature below 15°C.
Parts of catalyst M for 100 parts of resin 1 2 Geltime at 15°C in min. 74 28 Geltime at 20°C in min. 48 19 Geltime at 25°C in min. 30 10

Technical Details & Test Data
- Additives
Since certain pigments, fillers or extra styrene may the affect properties of CRYSTIC R 115 PA 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.
Packaging & Availability
- Packaging Type
- Packaging
- Crystic® R115 PA is supplied in 225 kg or 1100 kg containers. Bulk supplies can be delivered by road tanker
Storage & Handling
- Storage
- Crystic® R115 PA should be stored between 5°C and 25°C in the original, unopened container in a dry, well ventilated place. Protect from freezing and direct sunlight. Avoid contact with oxidizing agents. If stored outside of these recommendations, shelf life will be significantly reduced.
