Tinplate is coated with epoxy resin through a process called electrostatic powder coating. The tinplate is first cleaned and prepared to ensure proper adhesion of the epoxy resin. Then, an electrostatic charge is applied to the tinplate, creating a static field that attracts the epoxy resin particles. The epoxy resin powder is then sprayed onto the tinplate, where it adheres to the surface due to the electrostatic attraction. Finally, the coated tinplate is baked at high temperatures to cure the epoxy resin, creating a durable and protective coating.
Tinplate is coated with epoxy resin through a process known as electrostatic spraying or roller coating.
Tinplate is typically coated with epoxy resin through a process known as electrostatic spraying or electrodeposition. In this process, the tinplate is first cleaned and pre-treated to ensure proper adhesion. Then, a positively charged tinplate is immersed in an epoxy resin bath containing negatively charged epoxy particles. The resin particles are attracted to the tinplate surface and adhere electrostatically, forming a uniform coating. The coated tinplate is then cured at high temperatures to harden the epoxy resin, resulting in a durable and corrosion-resistant finish.
