Spraying equipment manufacturers introduce the spraying process

As we all know, the surface paint coating process of furniture, cabinets, and wooden handicraft manufacturers is mainly spraying, and the paint used is usually NC, PU, PE. With the development of paint coating technology and the enhancement of consumer awareness, a new type of paint-UV paint has emerged. UV paint is adopted by the majority of wood products manufacturers with good environmental protection, chemical resistance, physical damage resistance, high hardness tester and fast drying.

1. Application industry

Mainly used in wooden doors, furniture, stairs, cabinets, handicrafts and other wood products production enterprises.

Second, the coating process and requirements:

Spray PU white background (two→ dry sanding →spray PU color base (two) → dry sanding →spray UV topcoat→IR leveling→ UV curing.

Key factors: 1. After spraying two PU color bases, it must be dry, otherwise it will affect the adhesion between PU and UV, and after drying, it is necessary to do fine sanding, on the one hand, it is conducive to adhesion, on the other hand, the board surface is more beautiful.2. The amount of UV paint spraying must be moderate, not too thick, otherwise the paint layer will crack due to the reaction force of the UV paint itself.3. Leveling and UV curing time must be mastered.
