- Product Highlights
- Crestafire® P1-8001 is derived from sugar cane waste and therefore bio sourced without affecting the planet resources dedicated to animal or human being consumption.
- It is capable of rail EN45545-2 standard highest HL3 requirement performances when appropriately combined with Scott Bader gelcoat.
- It is halogen free, does not contain heavy metals. Resin system color is dark brown / black.
- Product Features
It provides excellent handling properties and wetting of the reinforcements. It is recommended for use when eco- composites with excellent low smoke, low toxic fume emissions and fire-resistant laminates is desired.
Key features are:
- Highly ecological (carbon neutral) and fully non-toxic matrix material
- Inherently fire resistant with very low flammability and low smoke release properties
- Low toxicity and emissions for improved operator health and safety
- Low environmental impact
- High Tg and stiffness
- 100% Plant-based resin
- Similar mechanical properties to conventional phenolic resins
- Low water uptake in composite applications
- Short processing/cycle times and cure temperature as low as 80°C possible
- Compatibility with natural and mineral fibers (e.g., Flax, Hemp, Sisal, Jute, Kenaf, wood-cellulose based fibers such as Rayon, recycled carbon fiber, E-glass)
- Compatibility with Scott Bader Crystic® and Crestafire® gelcoats.

- Produt Application
Crestafire® P1-8001 has been designed for use in contact molding techniques, such as hand lay-up and spray molding and is typically used in non-structural or semi-structural components. The reticulation process is similar to phenolic resins, with a better mold turnaround time and a better aspect of parts once out of the mold.
Before use
Crestafire® P1-8001 should be allowed to attain workshop temperature (18°C - 20°C) before use. It requires only the addition of a catalyst to start the curing reaction. The catalyst should be thoroughly incorporated into the resin, using a low shear mechanical stirrer where possible.
Additives
The addition of fillers or pigment pastes can adversely affect the properties of the cured laminate.
Formulation
The backbone of Crestafire® P1-8001 is formed by condensation reaction of furfuryl alcohol. To reduce the viscosity and thus to enhance the process ability, typically water is added as a solvent - around 4% w/w of water is recommended for optimum HLU processing. It requires the addition of acid catalysts and heat to start the curing reaction.

Crestafire® P1-8001 is supplied in 30kg plastic kegs, 225kg drums & 1100kg containers.
Storage & Handling
- Shelf Life
- 6 Months
- Storage Information
Crestafire® P1-8001 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.
- Catalyst Cure System and Pot Life
Three possible acid catalyst cure systems and curing cycles are shown in the table below. The catalysts should be added to the resin using a medium/high shear mechanical stirrer to ensure thoroughly dispersion within the resin.
