To effectively counteract this, Buser Oberfl\u00e4chentechnik AG offers specialised corrosion protection coatings that are optimally tailored to the material, area of application and environmental conditions. With a broad portfolio of coating technologies, Buser ensures that your components remain protected, functional and economically viable in the long term.\u00a0<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-layout-1 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.buser-ot.ch\/en\/contact\/\">Contact us now!<\/a><\/div>\n<\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Why a coating against corrosion is indispensable<\/h2>\n\n\n\n<p>Corrosion refers to the gradual decomposition of metallic materials through chemical or electrochemical reactions with their environment. The best-known case is the rusting of iron \u2013 but aluminium, stainless steel and alloyed steels are also at risk under certain conditions. The consequences range from visual defects and loss of function to safety-critical damage.\u00a0<\/p>\n\n\n\n<p>Increasing environmental pollution \u2013 such as air pollution, aggressive industrial atmospheres or salty moisture in offshore environments \u2013 is placing ever greater demands on corrosion protection. Components that come into contact with water, acids, alkalis or solvents require permanent protection that goes far beyond conventional coatings.\u00a0<\/p>\n\n\n\n<p>Corrosion-resistant coatings act as a barrier between the material and the environment. Depending on the technology used, they not only offer protection against oxidation and material degradation, but also additional functional properties such as chemical resistance, temperature resistance or electrical insulation.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Coating technologies<\/h2>\n\n\n\n<p>Depending on the area of application, medium and substrate, different processes are required to protect metals effectively and permanently against corrosion. Buser offers a wide range of state-of-the-art <a href=\"https:\/\/www.buser-ot.ch\/en\/surface-coating\/\" target=\"_blank\" rel=\"noreferrer noopener\">coating technologies<\/a> that can be individually tailored to your requirements.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Powder coatings \u2013 fluoropolymers for corrosion protection on steel and aluminium components<\/h3>\n\n\n\n<p><a href=\"https:\/\/www.buser-ot.ch\/en\/surface-coating\/synthetic-coating\/\" target=\"_blank\" rel=\"noreferrer noopener\">Powder coatings<\/a> with fluoropolymers such as PTFE, PFA, FEP, ETFE or PVDF are among the most effective solutions in industrial corrosion protection. They form a dense, pore-free barrier against external influences and also offer <strong>further functional advantages<\/strong>:\u00a0<\/p>\n\n\n\n<ul>\n<li>Reliable protection against moisture, chemicals and aggressive gases\u00a0<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>Non-stick properties and very low friction coefficients\u00a0<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>High temperature resistance (in some cases above 250 \u00b0C)\u00a0<\/li>\n<\/ul>\n\n\n\n<ul>\n<li>Resistant to severe chemical and thermal stress\u00a0<\/li>\n<\/ul>\n\n\n\n<p>We use a multi-stage sintering process in which the powder is melted under controlled conditions and permanently bonded to the substrate.
