Rigid composite moulds

Brush-applied for glass-fibre-reinforced polyester moulds. Confirm compatibility of the complete system if using epoxy backing. Before first use, fully cure the mould and prepare its surface with a cleaner, sealer and release agent.

Requires spray equipment and is intended for glass-fibre-reinforced polyester moulds. Confirm compatibility if using another backing material. Before first use, complete curing and prepare the surface with a cleaner, sealer and release agent.

Allow for heat curing of the mould to achieve the gelcoat's performance. If using prepregs, test the gelcoat and backing together with your equipment and manufacturing cycle.

Apply the backing while the gelcoat remains tacky; if it has cured, sand and degrease before laminating. The mould needs post-curing to achieve its thermal performance. Distinguish a short process peak from continuous operation.

Let the gelcoat cure before laminating and check adhesion with the specific backing resin. Colour is chosen from the commercial variants; it does not change the gelcoat's role.

Use equipment suitable for this viscosity and test adhesion with the chosen laminate before making the complete mould. Allow the gelcoat to cure before applying the backing.

Check adhesion between the gelcoat and the epoxy system used behind it. Apply and cure the surface layer before starting the mould backing.

Control film thickness and the mould's thermal cycle. If the process includes prepreg, test the complete system first: adhesion and finish depend on the laminate and cure.

Allow for heat curing before demoulding and post-curing of the complete system. The black variant has the same surface role as the other pigmented versions; check its compatibility with the backing.

Keep the wet film between 0.4 and 0.6 mm. Before first use, fully cure and prepare the mould surface with a cleaner, sealer and release agent. For heated cycles, allow for post-curing the complete system.

Requires spray equipment and even application, avoiding build-up in corners. Before first use, complete curing and prepare the mould surface with a cleaner, sealer and release agent following the specified procedure.

This intermediate layer sits between the gelcoat and backing. Plan all three layers and their application times to build the complete mould.

The backing is built with glass-fibre mat. Low shrinkage requires sufficient thickness applied in one operation; it is not achieved with any thin laminate. Also specify a gelcoat and release agent compatible with the complete system.

The Crystic mould system combines 15PA gelcoat, VE679PA skincoat and RTR4010PA backing with glass-fibre mat. The thickness laminated in each operation and post-curing determine shrinkage and mould performance.

Crystic VE679 PA Low-Shrinkage Vinyl Ester-DCPD Resin: Intermediate laminate layer between gelcoat and backing to improve the surface finish.

To make the mould, applying 7090/7091T gelcoat first, allowing it to dry and then laminating with 1040/1041HT is recommended. You need equipment to heat the mould before demoulding and complete the post-cure.

Match the mould's operating temperature to the chosen system and cure. The standard options for this reference are not equivalent to the specific HT formulations for prepreg tooling.

15PA vinyl ester gelcoat is recommended for the mould surface, with a VE679PA skincoat before the infused backing to improve the finish. Low shrinkage depends on curing; add accelerator and catalyst separately, never mixing them directly with each other.

The process requires heating before demoulding and a subsequent post-cure. Consider the mould size and available heating equipment; the documented combination with 7090 gelcoat is 1500/1504.

Allow for initial heating before demoulding and a full post-cure of the tooling. The gelcoat, backing and other materials must withstand the same manufacturing cycle.

Check that you have an oven suitable for the complete mould and its post-cure. The initial cure allowing demoulding does not by itself deliver final thermal performance.

The mould needs an initial cure before demoulding and a subsequent post-cure to achieve its thermal performance. Check oven capacity and the complete system's resistance to the selected cycle.

Plan casting volume and thickness, as well as the post-cure required to achieve final performance. Conditions must suit the size and geometry of the mould.
