Wire Bar Coater

Wet Film Application Rod

Product Description:

Qualtech Products Industry Wire Bar Coater and Spiral Bar Coater are Wire Wound Drawdown Bars engineered of Stainless Steel and wire shaped in the form of a cylindrical bar wound with Stainless Steel rod offering high precision, high reliability, high repeatability and advanced longevity.

This Spiral Bar Coater is designed and engineered for applications in the paint & coating industry to apply surface coatings of a specified thickness with high precision onto samples.

This professional Wire-Wound Drawdown Bar is available in a wide range of sizes to best meet professional surface coating application challenges.

The Wire Bar Coater shows a spiral bar shape – wire bar shape – and is designed to drawdown a film (paint, coating, ink) on a sample surface with high accuracy and high precision. This sample surface is usually a thin sheet or panel, e.g. a Black/White Test Chart, a glass panel, metal panel or a wood board.

To apply a film with the Wire Bar Coater the Wire-Wound Drawdown Rod is held with both hands or an optional high quality handle at both ends of the Wire-Wound Rod Applicator and is then carefully moved across the sample surface. The paint moves along the gaps between the Stainless Steel rod and forms a uniform thin film coating with a specified thickness. To ensure highest accuracy and highest precision the Spiral Bar Coater can be attached to an optional Drawdown Bar Holder or Drawdown Bar Handle and to the motordriven and electronic Automatic Film Applicator.

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

 This series of Wire-Wound Drawdown Bar Coaters is designed and engineered in accordance with International Test Standards including:
