Applications
Crestafire P1-8003 is engineered for hot cure, closed molding processes, ideal for non-structural or semi-structural components. Its outstanding FST performance makes it suitable for:
- Railway: Interior and exterior components meeting EN45545-2 HL3 standards.
- Building and Construction: Fire-resistant panels and structures.
- Public Transport: Components requiring low smoke and toxicity emissions.
The resin’s curing mechanism mirrors that of phenolic resins but provides enhanced mold efficiency and superior surface finish, depending on the curing conditions.
Processing Guidelines
Before Use
Ensure Crestafire P1-8003 reaches a workshop temperature of 18–20°C prior to processing. Blend the acid catalyst thoroughly using a low shear mechanical stirrer to achieve uniform dispersion.
Additives
Refrain from incorporating fillers or pigment pastes, as they may negatively impact the cured laminate’s properties. Seek guidance from Scott Bader’s Technical Support Department before adding any materials.
Surface Preparation and Compatibility
Crestafire P1-8003 is compatible with a diverse array of reinforcements and gelcoats, including:
- Natural and Mineral Fibers: Flax, hemp, sisal, jute, kenaf, wood-cellulose-based fibers (e.g., rayon), recycled carbon fiber, and E-glass.
- Gelcoats: Scott Bader Crystic and Crestafire gelcoats for enhanced surface finish and fire performance.
Verify that reinforcements and gelcoats are free of contaminants and properly cured before application to optimize bond strength and laminate quality.
Storage and Shelf Life
- Shelf Life: 6 months from the date of manufacture when stored between 5°C and 25°C in the original, unopened container.
