Conversion coatings for magnesium and steel alloys based on styrene-acrylic dispersion
Source abstract
Abstract
Physicochemical properties of polymerizable composite materials based on styrene-acrylic dispersion Lacroten 244 are considered. It is established that polymerizable gels at coaliscence on magnesium alloys form developed surface structures with good adhesion to metal and paints. The mechanism of formation of such structures and their adhesive properties were investigated by X-ray photoelectron spectroscopy and SEM analysis. It has been shown that the porous structures arise as a result of the chemical reaction of polycondensation between acrylic acid and surface magnesium hydroxides. On low-carbon steel, polymerization of the styrene-acrylic dispersion is accompanied by a strong interfacial interaction with subsequent increase in a uniform polymer coating. It is shown that styrene-acrylic dispersions can be used to obtain cost-effective conversion coatings on magnesium and steel alloys with high protective properties.
