- Formulation Guidelines
This resin should be allowed to attain workshop temperature (18°C – 20°C) before use. It requires the addition of acatalyst and accelerators to start the curing reaction. Accelerators and any additives should be mixed into the resin priorto any filler addition. Catalyst is the final component to be added immediately prior to use to begin the polymerisingreaction.
N.B. - Catalyst and accelerators should not be mixed directly together, since they react with explosive violence.For closed mold applications, the recommended catalyst is Dibenzoyl peroxide (50%) and the recommended accelerator is dimethyl aniline (DMA), Dimethyl paratoluidine (DMPT) can also be used in addition to DMA if required. The geltime canbe extended using commercially available inhibitors such as Inhibitor NLC-10.

- Additives
Crestapol 1212 may be highly filled (in some cases up to 200 parts per resin) with a selected range of fillers. The fillertype and particle size will vary depending on the application and/or the fire standard required and may influence thegeltime of the mix. For higher filler loadings viscosity reducing additives such as BYK 996 may be required. Users shouldseek advice from our Technical Services Department for any additive related queries.

Storage & Handling
- Pot Life
The following table demonstrates the effect of Inhibitor NLC-10 addition to a typical Crestapol 1212 formulation for closedmold applications. (0.4%DMA, 2% Dibenzoyl peroxide (50%) on resin and filled with 170 parts per resin ATH (Martinal ON-904)).
Inhibitor NLC-10 (on Resin) Typical Geltime (mins) at 20oC 0.0% 27 0.1% 48 0.2% 71 *Please note these are typical gel times under lab conditions. On site pot life tests are recommended before commensing closed mold processes to evaluate geltime under local conditions.
- Storage
Crestapol 1212 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.
