Conductive coating versions are also available. Aromatic compounds (such as, diphenylmethane diisocyanate (MDI) and toluene diisocyanate (TDI)) contain bonds that can absorb UV radiation, which leads to their breakdown and the undesirable yellowing of the coatings. There are many types of metal sealants on the market, many of which are designed to be used with specific metal types. Factory-applied, solvent-based systems (including high-solids formulations) are widely used in the furniture, cabinetry, and flooring industries. Specialized polyols, such as polycaprolactones, are preferred for some applications. by Alan Cain, Group Leader/Research Chemist, Chemline, Inc. Metals make it possible to have a variety of products, such as industrial production equipment, automobiles, aircraft, or consumer electronics. Designed to hide profile and surface imperfections, our primers and sealers promote adhesion of topcoats to the substrate for great results every time. The Product Finishes division is dedicated to the unique finishing needs of OEMs, tier suppliers, specifiers, global brands and product finishers. Polyurethane is a very common type of metal sealant. So don’t be surprised if we ask you lots of questions as we need to fully understand your problem and requirements. Premium coating solutions for surfaces of all types, from development right through to application – to help your products perform better. In general, polyurea coatings are preferred as topcoats for rapid curing applications (fast turnaround times), the coated substrate will be exposed to extreme conditions and appearance is not a key concern. The crosslinking present in polyurethanes means that the polymer consists of a three-dimensional network and molecular weight is very high. As a key industrial coating solutions company, we take pride in our workmanship. Thus, they are often used in the same applications that can use PUs. Questions of a Do It Yourself nature should be MagnaCoat® surfaces are heavy-duty fluoropolymer coatings which are pinhole free. While traditionally solvent-based, two-component (2K) coating systems, polyurethanes are also available as 1K water-based PU dispersions, 2K waterborne systems, and high- and 100%-solids 2K formulations. We won’t simply offer you the cheapest coating or the one that suits us – we’ll offer you what we believe is the best for the job. As a result, it is possible to achieve PU coatings that range from very flexible (elastomeric) to very rigid. Click the link below for more information on xylan coatings.xylan® coatings >>, MagnaCoat® surfaces are heavy-duty fluoropolymer coatings which are pinhole free. Polyureas, which can be sprayed in poor conditions including extreme temperatures and high humidity, are commonly used for outdoor or on-site applications. Polyurethane paint is the one coating that is suitable for almost any application on metal surfaces. Polyethers, polyesters, and polycarbonates are the polyol types most widely used for polyurethane and hybrid polymer production. Conventional technology: epoxies Impreglon UK uses a particularly high quality Polyurethane for its coating which can be pigmented. These chemistries offer a range of properties suitable for different application conditions and performance needs. Here are the most commonly used sealants for metals and the metal types to which they should be applied. Developments in both raw materials and application equipment have helped overcome these shortcomings. Conductive coating versions are also available.Fluoropolymer Coatings >>. Chemline’s polyurea and polyurethane coatings for metal surfaces are environmentally friendly and offer a fast-setting protective coating. Apply to wood or metal. The customizability of polyurethane/polyurea hybrid coatings has led to their use in a variety of applications where the high performance of polyureas and an attractive finish are both desired. We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services. However, the application of hybrid coatings is less complex (easier impingement mixing) than that of polyureas, although plural component spray equipment and applicator training are still required. STEEL-IT Primer #2203 combines a modified alkyd resin, selected silicates, and iron oxides with Type 316L leafing pigment to produce a long-lasting primer for structural steel and other metals requiring good rust-inhibiting qualities. If we coated the top of our racks, would this product stand up to having steel pipe rolled on top of it? Everything You Need to Know About Using ... Everything You Need to Know About Using Metal Sealant for Painted Metal. Historically, in non-critical industries, corrosion was treated as a repair and maintenance issue. We welcome your comments and Hybrids – the best of both Examples include OEM waterproofing applications and rail and barge coatings. Polyurea coatings are 100% solids, zero-VOC formulations that cure rapidly (as little as 30 seconds) without the need for a catalyst or heat, even at low temperatures (down to -°20 C). Special polymers (fluoropolymers, such as PTFE) reduce the surface energy of the substrate surface and prevents many different substances from sticking. The ratios of these various ingredients are varied to achieve different results. In addition we have corrosion resistant coatings where corrosion is prevented from happening due to the non-porous nature of the protective coating. Polyurethanes It comes in both a semi-solid form for sealing joints and in a liquid form for sealing large surfaces of metal. Due to the nature of the urea linkage, they are not sensitive to moisture; no blistering occurs, even when polyureas are applied on substrates in the presence of liquid water. Plastic finishing has its own set of specialized requirements — and we can help you meet them. The #1002 Polyurethane is also available in handy aerosols for easy touch-ups and small … The TempCoat® range is the family name given to the fluoropolymer coatings applied by Impreglon UK. The PlasmaCoat® method combines the outstanding hardness and wear resistance of thermally sprayed metal and ceramic coatings with the non-stick and sliding properties of polymers (both fluoropolymers and other polymers).
