- Formulation Guidelines
The following formulations are recommended for laminating.
Parts by Weight Formulation Crystic 123PA Crystic 124PA 100 Catalyst M or MEKP M-50 1 – 2.5 Curing should not be carried out at temperature below 150C and the resin must be allowed to attain workshop temperature before being formulated for use. These resins require the addition of catalyst only to start the curing reaction. The catalyst must be thoroughly stirred in the resin.
- Gel Time
The amount of catalyst and the ambient temperature control the gel time of the resin formulation. The following table shows the gel time of 100 pbw Crystic 123 or 124 containing various levels of Catalyst M.
Parts of Catalyst to 100 parts of catalyzed resins 1.0 1.5 2.0 Gel time in minutes at 25°C 37.5 23.25 16.5 Gel time in minutes at 30°C 29 18 12.5

Packaging & Availability
- Packaging Type
- Packaging
- Crystic® 123PA and Crystic® 124PA are supplied in 225kg steel containers. For shipping purposes they are Class 3.3 in the IMCO Code (page 3379).
Storage & Handling
- Storage
- Crystic® 123PA and Crystic® 124PA 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.
