BMB Curtain Coating --Coating Method for Water based Pressure Sensitive Adhesives

摘要

Curtain-coating is a well known and state of the art coating method especially in the photo and film industry and for other special applications like carbonless papers, thermosenstive or ink jet material. BMB studied the fundamentals of this technology, advanced the method and brought it deliberately to market maturity, especially for coatings of water based pressure sensitive adhesives. The main motivation to develop a new method for the coating of pressure sensitive adhesives was due to the market demand for higher production speeds on coating lines. Apart from this demand, BMB's other important goal is achieving an improved coating surface with our coating heads. This should finally lead to a possible reduction of the coating weight for given functional requirements of a coating.
