French to English Tech/Engineering Manufacturing revêtement antiadhésif

Good evening,

“En ce qui concerne la préparation de la composition aqueuse A, il est nécessaire d’incorporer au moins 5% en poids d’au moins un oxyde métallique par rapport au poids total de la composition A pour former un film ayant après cuisson une épaisseur d’au moins 10 microns. Si par contre on a plus de 30% en poids par rapport au poids de la composition A, celle-ci n’est plus stable. »
My translation :
As for the preparation of the aqueous composition A, it is essential to incorporate at least 5% in weight of at least a metal oxide with respect to the total weight of composition A to form a film having after cooking a thickness of at least 10 microns. If however, there is more than 30% in weight with respect to the weight of composition A, the latter is no longer stable.

I don’t know if, cuisson= cooking, here as it is about the manufacturing method of a pan with a non-stick coating, I have already used “curing” for “étuvage” so I’m at a loss…

Thank you
