Acrylic hybrids combine the acrylic resin with an epoxy binder.
They are somewhat better than a epoxy-polyester / hybrid but still not considered acceptable for outdoor use. The mechanical properties that are characteristic in epoxies are a benefit of these materials and they have much better flexibility than other acrylics. Because of their good appearance, tough surface, exceptional weatherability, and excellent electrostatic application characteristics, acrylics are frequently used for applications on products that have very high quality standards. Appliances, automobiles and other products that require durability and long life inRead More …
Difference between cold rolled steel and hot rolled steel
COLD ROLLED STEEL:The most common of the metals encountered by the jobshop powdercoater, this product is roll formed to a close tolerance and a fine surface finish, suitable for stamping, forming, and moderate drawing operations. This material can be bent flat upon itself without cracking. Good base for phosphate conversion coating. Pretreatment recommendations are Clean, Phosphate, rinse, and seal or deionize rinse.
