Curtain Coating

Curtain Coating

Curtain coating is one of the three most prominent pre-metered coating methods. Curtain coating has two outstanding advantages: it can apply thin liquid layers to irregular surfaces, and it can coat at very high speeds. The first capability is made possible by the large distance between the coating die and the moving surface, and also the impinging velocity of the falling liquids sheet which is usually much higher than the vertical velocity component of the substrate motion.
