Mobile phone spraying technology: two-component PU primer+PU topcoat or leather paint

Drying is carried out using infrared radiation and hot air circulation, with two coats and two ovens equipped with a dedicated 165M oven for one-time drying

Characteristics and precautions of two-component PU primer+PU or leather paint:

Mainly used for spraying on metal materials and PA+GF surfaces, the two-component PU primer is mainly used to increase the adhesion of the paint, and the PU and leather paint on the surface can increase the feel of the product (relatively soft); During construction, it is important to pay attention to the use of blended oil for 3-4 hours. PU and leather paint also belong to the dual liquid type paint, which requires the addition of a certain proportion of curing agent and high-temperature baking drying. During the construction process, we now use a precise automatic oil mixing system to mix and blend paint, which greatly saves costs.
