Application Bar Holder

Application Bar Holder

Accessory for Laboratory Applicators

Clamping accessory for uniform and reproducible application of coatings

The NK-AT3900 Manual Applicator Holder is NK by Neurtek’s standard accessory for securing test cards during the manual application of coatings, paints and varnishes. Its robust design, featuring a clamping mechanism and non-slip rubber base, ensures that the test card remains completely secure whilst the applicator glides over it, eliminating accidental movements that lead to non-reproducible results.

Available in two widths —180 mm and 235 mm— it adapts to both short applicators (Bird, Baker and standard-size square bars) and long applicators (spiral and large-format Bird bars), being compatible with the entire range of NK by Neurtek manual applicators.

Application

  • Quality control of paints and varnishes: preparation of samples for opacity, hiding power, colour and gloss tests on contrast cards.
  • Industrial coatings testing: application of films of controlled thickness using Bird, Baker, quadrangular and spiral bars.
  • Formulation laboratories: development and comparison of formulations through reproducible applications.
  • Production control: rapid in-line verification of coverage and opacity using manual applicators.
  • Education and research: testing in university laboratories or R&D centres where reproducibility is required without an automatic applicator.

Features

  • Integrated clamp that holds the test card firmly in place, preventing movement during application. 
  • Base with non-slip rubber that secures the test board to the work surface. 
  • Special rubber sheet for use with manual applicators: cushions unevenness and improves the uniformity of the applied film. 
  • Compatible with Bird, Baker, square, spiral bar and any other manual coating applicators. 
  • Two models available: 180 mm (short bars) and 235 mm (long bars). 
  • Robust, low-maintenance construction, suitable for continuous use in the laboratory and in production.

FAQS

Depending on the model, it can be used with application bars, Baker applicators, Bird applicators, square applicators and other systems used to produce films of controlled thickness.

The holder helps to maintain more uniform application conditions, reducing variations caused by speed, pressure or the operator’s experience.

Yes. Even small differences in thickness can significantly alter the results obtained in numerous coating tests.
