摘要:
An aluminum fluoropolymer laminate and a method for making such a laminate which includes conversion coating the aluminum and bonding the fluoropolymer onto the conversion coated aluminum is described.
摘要:
A method for forming a chromate conversion coating on aluminum surfaces is described in which an aluminum surface is immersed in an aqueous acidic solution containing hexavalent chromium and the aluminum surface and the solution are subjected to ultrasonic energy thus reducing the need for including environmentally harmful accelerator components in said solution.
摘要:
In a process for producing a chromium protective coating on a zinc/iron alloy surface the surface has applied thereto an aqueous composition including chromium, perchlorate and fluoride ions with the chromium ion being the only metal ion present before application to the surface.
摘要:
A corrosion resistant conversion coating consisting essentially of hexavalent chromium, fluosilicate ion, nitrate ion, and a source of soluble barium. Improved paintability and corrosion resistance of the aluminum surface is claimed adapting the aluminum for siding and other architectural uses.
摘要:
PROCESS OF FORMING ON A SURFACE A DECORATIVE COATING RESISTANT TO CORROSION AND ABRASION WHICH COMPRISES FORMING A LOOSELY ADHERENT PROOUS FILM OF PARTICLES ON THE SURFACE, APPLYING A SILICATE SOLUTION TO THE FILM COATED SURFACE, DRYING THE SILICATE-FILM COATING AND HEATING THE DRIED SILICATE-FILM COATING TO INSOLUBILIZE THE SILICATE.
