DESCRIPTION

As a common resource, the usage of LPG (liquefied petroleum gas) has increased greatly in recent years. The demand for LPG cylinder is also increasing with the extensive use of LPG. In the process of manufacturing LPG cylinders, final surface finishing is also very important except selecting high-quality materials. Qualified surface treatment is very wear-resistant, corrosion-resistant. It can also prolong LPG cylinders’ service life effectively. Then, how to make the perfect surface treatment of LPG cylinders? LPG cylinder powder coating is an ideal solution. The film cured on the surface of LPG cylinder powder coating is very strong, and this treatment is more environmentally friendly than ordinary painting. Powder color can also be selected to meet the requirements of the appearance.

LPG cylinder powder coating is a process of coating metal with powder form and baked to a fluid state to bond it to the metal surface. This process can create a harder finish that is tougher than conventional paint. It is mainly used for coating metals, such as appliances, automotive parts, and other hardware. Since it is not a liquid product, it requires no solvent to keep the binder and filler components in a liquid suspension form. It's very friendly to environment, easy to use, cost effective, and tough.
