Crestapol® 1212

• Crestapol® 1212 is a tough, low viscosity resin with a rapid cure, which can be highly filled with selected grades of alumina trihydrate (ATH).
• Highly filling this resin with ATH allows a very high level of fire & smoke performance.
• It is designed for closed mould applications, including vacuum infusion with suitable reinforcements and pultrusion processes. (Separate Crestapol pultrusion and closed mould guides are available).

¹ Curing Schedule – 24 hours at 20°C, 3 hours at 80°C

² Curing Schedule – 24hours at 20°C, 5 hours at 80°C, 3 hours at 120°C

³ Made with 4 layers 450g/m² PB CSM, Curing Schedule – 24 hours at 20°C, 16 hours at 40°C

• This resin should be allowed to attain workshop temperature (18°C – 20°C) before use.
• It requires the addition of a catalyst and accelerators to start the curing reaction.
• Accelerators and any additives should be mixed into the resin prior to any filler addition.
• Catalyst is the final component to be added immediately prior to use to begin the polymerising reaction.
• N.B. Catalyst and accelerators should not be mixed directly together, since they react with explosive violence.
• For closed mould 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 can be extended using commercially available inhibitors such as Inhibitor NLC-10.

The following table demonstrates the effect of Inhibitor NLC-10 addition to a typical Crestapol 1212 formulation for closed mould applications.

(0.4%DMA, 2% Dibenzoyl peroxide (50%) on resin and filled with 170 parts per resin ATH (Martinal ON-904)).

• 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 oxidising agents.
• If stored outside of these recommendations, shelf life will be significantly reduced.
