I have made my first part using CG50 gelcoat, but it delamimate, so I wonder if it´s possible to spray epoxy resin in the mould instead off CG50, let it cure till it´s tacky, add reinforcement and then infuse?

Best regards

Hi,

It could be a couple of issues causing the de-lamination.  Common issues include leaving the gelcoat too long, too thick gel, cool temperatures, incorrect mixing and incorrect mixing ratio.

In terms of using an epoxy, we do not have a specific epoxy gelcoat.  Using a normal release agent would likely cause problems as it is not thick enough to lay evenly on a chemical release agent, meaning a high chance of the resin fish-eying on application.

Many people will infuse without a gelcoat then either leave the parts as they are or use a UV stable lacquer or clear coat to give a final shine and UV protection.

Hi Warren Thanks for reply

Yes we have after reading all post (a lot) regarding this issue, and figuerd out that there are too many parameters using GC50 for a garageprojcet as ours. The sollution I guess will be - infusing without gelcoat or epoxy as first layer.
