Usage Guidelines
Preparation
-
Make certain that Crestafire P1-3001E attains a working temperature between 20°C and 25°C for the best application results.
-
Gently mix by hand or with a low shear stirrer to reintroduce any slight filler settling, ensuring consistent ATH distribution without introducing air.
-
Incorporate 1%–2% Crystic® Accelerator G (cobalt-based) and 1%–2% medium reactivity MEKP (50%) catalyst, mixing each individually using a low shear mechanical mixer. To achieve quick demould times, incorporate up to 0.1% DMA or replace MEKP with an AAP-type catalyst, seeking technical support for assistance.
Application
- Methods:
- Hand Lay: Utilize a resin-to-glass ratio of about 2.5:1 because of the resin’s elevated specific gravity (1.5). Distribute uniformly using rollers or brushes to prevent air from getting trapped.
- Closed Mould (RTM/Vacuum Infusion): Enhance injection pressures and mould configurations to utilize the resin’s advantageous viscosity for consistent filling and reduced voids.
- Catalyst and Accelerator: Utilize 2% Accelerator G and 2% MEKP for a 20-minute geltime at 25°C. Modify within 1%–2% to fit environmental conditions or production requirements.
- Lamination: Add additional layers within 24 hours, allowing at least 1–2 hours after the first application to guarantee effective interlayer bonding.
- Do:
-
Keep the workshop temperature between 20°C and 25°C.
-
Mix the resin prior to use to guarantee even distribution of the filler.
-
Combine catalyst and accelerator individually with low shear.
-
- Don’t:
-
Incorporate fillers or pigments, as they affect fire behavior and flow characteristics.
-
Utilize high shear mixers, as they can incorporate air and influence curing.
Post-Curing
-
-
For typical applications, cure at 20°C–25°C for a duration of 24 hours.
-
To achieve the best fire performance and mechanical characteristics, cure in an oven for 16 hours at 40°C or 3 hours at 80°C following 24 hours at 20°C
Manufacturing Considerations
Storage
-
Keep in original, sealed containers at temperatures ranging from 5°C to 25°C in a dry area with good ventilation.
-
Shield from freezing, direct sunlight, and oxidizing substances.
-
The shelf life is 5 months; keeping it outside these conditions greatly diminishes stability.
Packaging
-
Offered in 25kg and 225kg containers, suitable for different production sizes.
