Usage Guidelines

Preparation

Verify that Crestafire P1-3001PA attains a workshop temperature of 18°C–23°C for the best application results.
Mix thoroughly by hand or with a low shear mixer to reintroduce any settled ATH filler, ensuring even distribution without incorporating air.
Incorporate 1.0%–2.0% medium reactivity MEKP (50%) catalyst and blend well using a low shear mechanical stirrer. To achieve quicker demould times, acetyl acetone peroxide (AAP) catalysts can be utilized; seek technical support for assistance.

Application

Methods:
- Hand Lay/Contact Molding: Utilize a resin-to-glass ratio of about 2.5:1 to compensate for the resin’s elevated specific gravity. Use rollers or brushes to apply uniformly to reduce air entrapment.
- Closed Mould (RTM/Vacuum Infusion): Utilize the resin’s 4–6 Poise viscosity for superior mould filling, enhancing injection pressures and mould ventilation to minimize voids.
Catalyst Levels: Modify the MEKP catalyst in the range of 1.0%–2.0% to reach the preferred geltime (for instance, 23–27 minutes at 25°C using 1.5%–2.0% catalyst). For RTM, introduce catalyst using injection apparatus.
amination: Apply additional layers within 24 hours, allowing at least 1–2 hours after the first application to guarantee strong bonding between layers.
Do:
- Keep the workshop temperature between 18°C and 23°C.
- Mix the resin prior to use to guarantee even distribution of the filler.
- Employ gentle mixing to integrate the catalyst.
Don’t:
- Incorporate fillers or pigments, as they affect fire performance and flow characteristics.
- Utilize high shear mixers, as they can incorporate air and influence the curing process.

Post-Curing

For typical applications, cure at 20°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 for 3 hours at 80°C after resting for 24 hours at 20°C

Manufacturing Considerations

Crestafire P1-3001PA is designed for adaptability in composite production, facilitating hand lay, contact molding, and closed mould techniques. Its pre-accelerated, ATH-enhanced composition guarantees reliable fire performance and streamlines curing, making it perfect for high-volume manufacturing. The 4–6 Poise viscosity of the resin promotes optimal flow in RTM and vacuum infusion, minimizing defects and cycle durations. In hand lay applications, the ideal resin-to-glass ratio of 2.5:1 enhances laminate durability and fire resistance, especially for railway and construction elements. Producers must adjust RTM devices to sustain uniform injection pressures and guarantee correct mould construction to prevent air entrapment. The anti-settling agents in the resin reduce filler settling, but it is crucial to stir well before application. In outdoor uses, combining with suitable fire-retardant gelcoats and protective coatings boosts resistance to UV and moisture exposure. Fire testing specific to components is essential for confirming adherence to standards such as EN 45545-2, and technical assistance can help optimize laminate configurations, curing methods, and processing conditions tailored to individual project requirements.

Storage

Keep in original, sealed containers at temperatures ranging from 5°C to 25°C in a dry, well-ventilated space.
Shield from frost, direct sunlight, and oxidizing substances.
The shelf life is three months; keeping it outside of these conditions greatly diminishes stability.

Packaging

Offered in 25kg and 225kg containers, suitable for different production levels.

Health and Safety

Consult the Safety Data Sheet for comprehensive guidelines on the safe handling of Crestafire P1-3001PA and its catalysts. Wear suitable protective gear, maintain proper ventilation, and refrain from direct contact with oxidizers.
