Powder coating is insensitive to most factors of influence – during storage, application and direct operation of products. However, the baking temperature further affects the appearance, durability and protective qualities of the polymer film. The correct level of heating and curing time can be found on the package or from the manufacturer.<\/p><\/blockquote>\n

What will be the consequences of deviation from the technological process?<\/p>\n

\"\"<\/a><\/p>\n

Polymerization<\/h2>\n

External signs of overbaking of the paint are imperceptible at first glance, unless it was polymerized at a temperature three times higher than required. But in the process of using the part, it will turn out that the painted layer is fragile, easily scratched, and cracks form on it. Such overbaked paint is particularly vulnerable to bumps and dents, meaning a high risk of rusting with any damage.<\/p>\n

The hardening mode of the coating is not correct<\/h2>\n

In this case, the flaws are immediately noticeable, because it is quite possible to remove the paint with an ordinary knife or spatula. When bending, small particles can peel off. The coating is also of low quality and short-lived.<\/p>\n

In both cases, we are faced with insufficient adhesion, that is, the paint material does not penetrate well into all the irregularities of the metal and does not stick to it. Adhesion is one of the most important indicators for the protective qualities of paints \u2014 thanks to complete adhesion, it is possible to completely isolate the metal from external factors.<\/p>\n

\"\"<\/a><\/p>\n

Solution for the problem<\/h2>\n

A quality curing oven with reliable heating elements will be a good investment. It will reliably extinguish heat and save energy. A regular audit will help to determine the exact temperature inside the oven \u2014 it happens that due to a malfunction or defect in the design, the product heats up more at the top and less at the bottom. Such cases often bring inconvenience to entrepreneurs, so it is better to detect and eliminate the defect earlier.<\/p>\n
