We all know that at present, many surface hardware products are sprayed with metal paint by spray gun. Of course, what metal objects need is a good-looking appearance, but the appearance of paint falling off will affect our appearance effect. Therefore, we need to put an end to this and find a solution.

1、 First, what are the metal materials?

It includes hardware, alloy, stainless steel, electrodeposited coating and other substrates,

2、 Causes of paint falling

1. The problem of poor adhesion often occurs when spraying paint. At this time, it is necessary to apply a layer of primer before oil injection.

2. Metal primer is the most widely used metal surface adhesion treatment water at present. Through engineering test and customer sample feedback, it has the best effect on hardware and electroplating spraying UV oil. Especially for water boiling, salt spray and other performance tests can pass. It is the best choice for metal bottom water.

3、 Specific operation coating process flow

Cleaning of hardware surface → spraying special treatment agent → drying at 60 ℃ for 5-10 minutes → spraying paint → testing after the paint is completely dry.
