- Formulation Guidelines
- This resin should be allowed to attain workshop temperature before use. Filler should be thoroughly dispersed and can be added up to 200PHR. It requires the addition of a catalyst and two accelerators to start the curing reaction.
- N.B. - Catalyst and accelerators should not be mixed directly together, since theyreact with explosive violence.The recommended catalyst is Trigonox 44B and the recommended accelerators are Accelerator G and dimethyl aniline (DMA). The geltimes that can be achieved depend on the levels of accelerators and catalyst.

- Additives
Crestapol 1216 may be filled with a variety of fillers, such as calcium carbonate or alumina trihydrate.
- Post Curing
Without post cure, Crestapol 1216 can reach above 90% of its total cure. Therefore, no post cure is required.

Storage & Handling
- Storage
Crestapol 1216 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 be above 30°C. Ideally, containers should be opened immediately prior to use. Where they have to be stored outside, it is recommended that containers be kept in a horizontal position to avoid the possible ingress of water.
