Anodizing duro de abrigo se hace en su mayor parte en un baÒo ·cido sulf�rico en 32 grados f. Yo personalmente no sÈ del abrigo duro verdadero ser hecho con el ·cido crÛnico. Si esto no se hace para el aviÛn que anodizing duro regular de abrigo es lo que usted quiere

Hard coat anodizing is mostly done in a sulfuric acid bath at 32 degrees f. I personally do not know of true hard coat being done with chronic acid. If this is not being done for aircraft than regular hard coat anodizing is what you want.
