Wire Bar Coater

Wet Film Application Rod

Product Description:

Qualtech Products Industry Wire Bar Coater and Spiral Bar Coater are engineered of Stainless Steel wire shaped in the form of a cylindrical bar wound with Stainless Steel rod ensuring precision, reliability and longevity.

These Spiral Bar Coaters are designed for applications in the paint & coating industry to apply a coating of specified thickness onto a sample based on Stainless Steel wire of predefined varying thickness.

The Wire Bar Coater shows a spiral bar shape – wire bar shape -and  is designed to accurately draw down a film (paint, coating, ink) on a sample surface. This sample surface is usually a thin Sheet, e.g. a Black/White Test Chart, a Glass Panel or a Wood Panel.

To apply a film with the Wire Bar Coater the Spiral Bar Coater is being held with both hands at the edges of the Wire Bar Coater and then carefully moved across the sample surface. The paint will move through the gaps between the Stainless Steel rod and and form a uniform thin film coating of specified thickness. For highest precision the Spiral Bar Coater can be attached to a Wire Bar Holder or Wire Bar Handle and to the motorized Automatic Film Applicator.

The Spiral Bar Coater is a very popular instrument to apply thin film based on its precision, reliability, user-friendly handling and compatibility with the Automatic Vacuum Film Applicator.

 This series of Wire Bar Coaters is designed and engineered in accordance with Internation Testing Standards, e.g. ASTM D4147 (Standard Practice for Applying Coil Coatings Using The Wire-Wound Drawdown Bar).
