Rust Bullet Application Spray & Non-Spray

Coating Application Methods Non-Spray

Roll

Roll (direct and reverse)

In direct roll coating, the applicator roll rotates in the same direction as the substrate moves. In reverse roll coating, metal feed stock is fed between the rolls as a continuous coil. The applicator roll rotates in the opposite direction of the substrate.

Dip

Dip refers to immersing a piece into a tank containing the coating material, removing the piece from the tank, and allowing it to drain. The coated piece can then be dried by force-drying or baking.

Dipping is extremely dependent on the viscosity of the coating, is very messy, and may be highly hazardous. The viscosity of the paint in a dip tank must remain practically constant if the deposited film quality is to remain high. More »
