Investigation of the barrier properties of silanes on cold rolled steel

3‐Aminopropyltriethoxysilane coatings have been deposited on stainless steel (SS) samples by means of an atmospheric pressure dielectric barrier discharge as an adhesive promotion layer in epoxy resin/SS composites. A multi‐diagnostic analytical approach (FTIR, XPS) was used for the chemical characterization of the deposited coating with regard to improvement of adhesively bonded joint strength. The effect of a plasma post‐treatment after the plasma coating deposition was compared to a thermal post‐treatment. Both enhanced the siloxane networking resulting in a significant adhesion improvement. Fracture strength between SS and epoxy was increased with more than 20 MPa.

“…These silanes were originally used as adhesion promoters between metal surfaces and organic resins [5][6][7][8]. Silane films are usually deposited by a simple conventional dip-coating method onto various metal substrates: aluminium and its alloys, iron and steels, galvanized steels, copper, zinc and magnesium alloys [9][10][11][12][13][14][15]. Silanol alkoxy groups are capable of hydrolysis in the presence of moisture and form silanols-Si(OH) [16], which may react with the metal hydroxide groups of the metallic substrate forming Si-O-Me-a covalent bonded layer on the metal surface [17].…”

This paper addresses the preparation and characterization of protective anticorrosion silane-and polyrhodanine-based bilayer coatings on a tested electrode substrate. Polyrhodanine (pRh) coatings were electrodeposited using the cyclic voltammetry technique on glassy carbon and stainless steel substrates. Isobutyltriethoxysilane (IBTES) films were deposited by the simple dipcoating method on steel substrates and then were stored in air (''aged''). The formed novel bilayer pRh/IBTES coatings were applied on the electrode surface as moderately thin (ca. 6-8 nm thick) layers and exhibited very good adhesion to the steel substrate. The physicochemical properties of pRh, IBTES and bilayer pRh/IBTES coatings were determined with the use of electrochemical, X-ray photoelectron spectroscopy and scanning electron microscopy techniques. The bilayer coatings consisting of a conducting polymer-pRh and silane-IBTES most effectively hinder the access of pitting-causing aggressive anions (chlorides) to the surface of stainless steel and exhibit better barrier properties compared to single-component pRh and IBTES coatings.
