Corrosion Protection.
 

Corrosion dictates the life span of a product and it is the main reason for the failure of many. There are a number of coating solutions aimed to tackle this problem, gels, paints, ceramic and conversion coatings. Coatings fail by a number of mechanisms including UV degradation, oxidation, penetration of pinholes and undercutting (filiform).  OxSiCoat chemically bonds to the surface metal creating a hermetic seal eliminating the possibility of filiform corrosion occurring. OxSiCoat’s non- porous glass outer shell, is UV, heat and weather resistant enabling it to withstand extreme elements without surface degradation. This combination of protective properties preserves the underlying metal. The transparency of the coating allows the natural beauty of the metal to be preserved.

OxSiCoat has a proven track record of success in standard corrosion tests, including salt spray laboratory tests as well as marine environment tests. It has passed manufacturing standards.

Results in tabs below are for OxSiCoat applied over a highly reflective aluminum surface. The results are compared to highest quality anodize and sealed aluminum.

  • The entire sample was anodized to a 1µ thick  film.  The left side was then coated with OxSiCoat.  
    The sample was then immersed in hot (70⁰C)  1M sodium hydroxide solution (pH 14).  Test was carried out until uncoated side of the metal dissolved completely, approximately ( 40min)
    Then sample was rinsed in DI water and inspected. 
    There was no  sign of any degradation to the OxSiCoat surface. No undercuts, no pinholes or discoloration were observed.

     

     

  • TL182 (11/2012) – Salt Spray test 480 hours; no optical changes comparing to original part, no separation of the protective coating and no corrosion on the substrate of testing component.
