Resin infusion

Calculate the time needed to wet out the whole part before the resin gels. Workshop temperature affects both flow and available time; work within the data sheet's conditions.

Check that the gel time allows your part to fill: temperature and catalyst level affect it. Allow for post-curing if you need optimum thermal performance and dimensional stability.

Define the reinforcement and check that you have equipment for the required curing cycle. Final thermal performance depends on this process.

Distribute resin with external infusion mesh or permeable or grooved and perforated cores, according to the part. Keep reinforcements dry and control temperature. Heat curing is required before demoulding, followed by post-curing to achieve final performance.

You need equipment for heat curing, with a reference cycle of 6 hours at 70 °C. Check that the whole part can be wetted out within the working time at the actual workshop temperature.

This option is for closed-mould injection. If your setup uses vacuum infusion, check the process requirements and documentation for the INF-G variant before applying parameters from the injection data sheet.

Organise flow to complete wet-out within the available working time. Allows demoulding after room-temperature curing; the maximum thermal and mechanical properties in the data sheet require post-curing.

Work in a closed mould and avoid moisture: this system is not recommended for hand lay-up or winding. High-temperature performance requires the staged post-cure in the data sheet.

Use in a closed mould and control moisture. Hand lay-up and winding are not recommended processes; plan post-curing before choosing it for a large part.

Use reinforcements suitable for the flow of a filled resin and check the complete resin, reinforcement and finishing system against the project's requirement. Post-curing improves final fire-retardant performance.

For the reference system with GCS1001E PA gelcoat, validate the complete laminate: reinforcement, thickness, finish and cure. The fire classification does not transfer to any part. This gelcoat is spray-applied and intended to be painted afterwards.

Crestafire GCS1001E PA: Spray gelcoat for the reference fire and smoke system with P1-3001PA. The complete part and its finish must be validated.
