Product catalog summary
Purpose and Application
The Drying Time Tester, Model 415, is designed to measure the degree of dryness of coatings according to ISO 9117, using a modified Bandow-Wolff method.
Design and Function
The tester features a light alloy cylinder fixed to a stand, with a pressure spring that applies a plunger force up to 250 N. The clearance between the plunger and base table is adjustable to match the test panel thickness. It includes loading weights of 20 g and 200 g for standardized loads under 2 kg. A cylindrical soft rubber disk ensures uniform contact pressure.
Conducting the Test
Tests vary by dryness degree:
  • Degree 1: Coating covered with ballotini, removed with a fine brush.
  • Degrees 2 and 3: Paper and rubber disks placed on coating, loaded with 20 g or 200 g for 60 seconds.
  • Degrees 4 to 7: Test panel placed on stand, covered with paper and rubber disks, loaded with 2 kg or 20 kg for 60 seconds.
Evaluation of Test
Post-load, the coating is evaluated based on ISO 9117 criteria, ranging from easy removal of ballotini (degree 1) to no paper adhesion and no visible changes under 20 kg load (degree 7).
Technical Data
Dimensions: 150 mm (W) x 300 mm (D) x 440 mm (H). Net weight: 4.5 kg.
Order Information
Order No. 00930131 includes the stand, weights, rubber disks, paper disks, ballotini dispenser, and glass beads, compliant with ISO 9117.

Technical Description Model 415-2

The Drying Time Tester, Model 415, is intended for the determination of the degree of dryness of coatings in accordance with ISO 9117 (modified Bandow-Wolff method). The Drying Time Tester, Model 415, consists of an light alloy cylinder which is fixed to a stand. The pressure spring integrated in the cylinder facilitates a plunger force of up to 250 N which is applied to the coating in a perpendicular motion by way of a lever mechanism. The clearance between the plunger and the base table can be set to the thickness of the test panel by adjusting the lever bracket accordingly. Loading weights...
