Preparation and Characterization of Silanes Films to Protect Electrogalvanized Steel
(Springer, 2018-03)
Silanes are an interesting alternative to chromate-based surface treatments for temporary protection of electrogalvanized steel. In this work, the protective behavior of 3-mercaptopropyltrimethoxysilane (MTMO), ...
Surface characterization of feldspathic ceramic using ATR FT-IR and ellipsometry after various silanization protocols
(Elsevier B.V., 2012-02-01)
Objectives. This study characterized the feldspathic ceramic surfaces after various silanization protocols.Methods. Ceramic bars (2 mm x 4 mm x 10 mm) (N = 18) of feldpathic ceramic (VM7, VITA Zahnfabrik) were manufactured ...
Protection of galvanized steel with silanes: its comparison with Chromium(VI)
(Springer, 2014-01)
The corrosion behavior of hot dip galvanized steel (HDGS) pre-treated with mercaptopropyltrimethoxysilane and a commercial sulfur-bearing silane was studied. Electrochemical polarization, electrochemical impedance spectroscopy, ...
Aniline-based silane as a primer for corrosion inhibition of aluminium
(Elsevier Science Sa, 2012-06)
Hybrid films based on polyaniline and polysiloxane moieties were successfully deposited on commercial aluminium alloy using N-(3- trimethoxysilylpropyl)aniline (AnSi) as primer. The spectroscopic studies conducted on both ...
Influence of cerium (IV) ions on the mechanism of organosilane polymerization and on the improvement of its barrier properties
(Pergamon-Elsevier B.V. Ltd, 2009-03-30)
In this work, the effect of cerium (IV) ammonium nitrate (CAN) addition on the polymerization of bis-[triethoxysilyl]ethane (BTSE) film applied on carbon steel was studied. The electrochemical characterization of the films ...
Silane as adhesion promoter in damaged areas
(Elsevier Science Sa, 2016-01)
Silanes have been studied as adhesion promoters between metals (aluminum, galvanized steel and steel) and paints such as polyurethanes. The objective of this work was to study γ-glycidoxypropyltrimethoxysilano (glymo) as ...
Electrochemical behavior of carbon steel pre-treated with an organo functional bis-silane filled with copper phthalocyanine
(Sociedade Brasileira de Química, 2008)
The bis-[trimethoxysilylpropyl]amine (BTSPA) film filled with copper phthalocyanine (Cu-Ph) was prepared by adding different concentrations of copper phthalocyanine - Cu-Ph and deposited on a carbon steel substrate using ...
