Technical Specifications

Liquid Resin Properties

Cured Resin Properties

• Fire Resistance: Exhibits excellent fire-retardant properties, reducing flame spread and smoke generation.
• Mechanical Properties: Provides strong tensile strength and durability when post-cured, suitable for demanding applications.

Curing Schedule: 24 hours at 20°C + 3 hours at 80°C or 16 hours at 40°C for optimal properties.

Usage Guidelines

Preparation

• Ensure Crestafire P1-2002PA reaches a workshop temperature of 18°C–20°C for optimal application performance.
• Stir gently by hand or with a low shear stirrer to ensure uniformity without introducing aeration.
• Add 1%–2% medium reactivity MEKP (50%) catalyst and mix thoroughly with a low shear mechanical stirrer to initiate curing.

Application

• Methods: Apply via spray or hand lamination techniques, depending on production requirements.
  • Spray: Use equipment with appropriate pump ratios and nozzle sizes for uniform application, ensuring consistent thickness.
  • Hand Lamination: Apply evenly with rollers or brushes, taking care to avoid air entrapment.
• Catalyst Addition: Use 1%–2% MEKP (50%) catalyst to achieve a geltime of 8–10 minutes at 25°C. Adjust catalyst levels within this range to suit ambient conditions.
• Lamination: Apply subsequent layers within 24 hours to ensure strong interlayer adhesion, with a minimum wait of 1–2 hours after initial application to allow partial curing.
• Do:
  • Maintain workshop temperature at 18°C–20°C.
  • Mix catalyst thoroughly with low shear to ensure uniform curing.
• Don’t:
  • Use high shear mixers, which can introduce air and affect thixotropy.
  • Add fillers or pigments, as they may compromise fire-retardant properties.

Post-Curing

• For standard applications, cure at 20°C for 24 hours.
• For optimal fire resistance and mechanical properties, oven-cure for 16 hours at 40°C or 3 hours at 80°C after 24 hours at 20°C.

Manufacturing Considerations

Crestafire P1-2002PA is designed for ease of use in composite manufacturing, offering flexibility for both spray and hand lamination processes. Its pre-accelerated formulation ensures consistent curing, reducing variability in production and enabling high-throughput workflows. The thixotropic nature prevents drainage on vertical surfaces, making it ideal for complex geometries in rail and construction components. Manufacturers should calibrate spray equipment to achieve uniform application and avoid over-application, which can lead to excessive heat buildup during curing. For hand lamination, proper roller techniques are essential to eliminate air bubbles and ensure laminate integrity. The resin’s fire-retardant properties are optimized when paired with compatible gelcoats and reinforcements, and component-specific fire testing is recommended to verify performance. Protective coatings are advised for outdoor applications to enhance durability against environmental exposure. For tailored guidance on laminate constructions or compatible additives, technical support is available through the manufacturer.

Storage
