Crestafire® P1-3001E

Crestafire® P1-3001E can be used for both hand lay and closed mold applications, including RTM and vacuum infusion, due to its favorable viscosity profile.  Its excellent fire, smoke and toxicity properties allow Crestafire® P1-3001E to be used for the most demanding applications in the rail, building & construction, and other public transportation industries.

Additives

The addition of fillers or pigments to Crestafire® P1-3001E will adversely affect the fire performance, flow properties and cure of this material and is therefore not recommended. It incorporates anti-settling additives to minimize filler settlement during storage and promote easy filler re-dispersion. Mild settling may occur after prolonged storage, so it is always recommended to stir the resin before use to ensure uniform filler distribution.

Before Use

• Crestafire® P1-3001E should be allowed to attain a working temperature of 20 - 25°C before use.
• Crestafire® P1-3001E is not accelerated so requires the addition of both, a cobalt-based accelerator, and medium reactivity MEKP type catalyst to start the curing reaction.
• The recommended accelerator is Scott Bader Crystic® Accelerator G which should be added to the resin at 1 - 2%. Medium reactivity MEKP type catalyst should also be added at 1 - 2% into the resin.
• The catalyst and accelerator should be thoroughly incorporated into the resin one at a time, using a low shear mechanical stirrer where possible.
• Where rapid demold times are required, up to 0.1% DMA can be added into the resin in addition to the above recommended cure system. Also, the MEKP catalyst may be substituted for an AAP type catalyst to speed up the cycle times even further.
• N.B. Catalyst and accelerator must not be mixed directly together as they can react with explosive violence.
• Due to the high specific gravity of Crestafire® P1-3001E, a resin to glass ratio of roughly 2.5:1 is recommended for hand lay applications.

Post Curing

For many applications, Crestafire® P1-3001E will perform adequately when cured at workshop temperature (20°C - 25°C). However, for optimum properties, and to achieve the highest fire performance, the components should be allowed to cure for 24 hours at 20°C, and then be oven-cured for either 16 hours at 40°C or 3 hours at 80°C.

* Curing Schedule – 24hrs at 20°C + 3hrs at 80°C
† Curing Schedule – 24hrs at 20°C + 5hrs at 80°C + 3hrs at 120°C

Properly cured laminates produced with Crestafire® P1-3001E resin and gelcoat Crestafire® GCS 1001E can achieve a rating of HL2 - R1/R7/R10/R17 according to rail standard EN 45545-2:2013.

Crestafire® P1-3001E is supplied in 25kg & 225kg containers.

Crestafire® P1-3001E 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. Stored outside of these recommendations, shelf life will be significantly reduced.
