Technical Description Model 419

Product catalog summary

Overview
The document provides a technical description and operating manual for the Levelling and Sag Tester, Model 419, which is used for determining the flow properties of coating materials. It adheres to standards ASTM D 2801, ASTM D 4400, and DIN 55 677.

Testing Principle
Wet film strips are applied to a substrate using a stainless steel paint applicator frame with slots of varying heights. The sag tendency is assessed in a vertical flow test, while the levelling tendency is evaluated when the specimen is horizontal. Visual examination is conducted after the coating hardens.

Design and Function
The applicator frame has slots on two sides:

Levelling Test: Features 5 pairs of slots with predefined widths and distances, graded from 250 µm to 4 mm.
Sag Test: Features 10 slots graded in 25-µm steps, from 75 µm to 300 µm.

Levelling Test (ASTM D 2801)
Wet film strips are applied horizontally. After hardening, the number of merged double strips is counted. Note: This standard was withdrawn in 1990.

Sagging Test (ASTM D 4400)
Method A: Wet film strips are applied to a contrast card and positioned vertically. The level is determined where the film has not spread to the strip below.
Method B: Similar to Method A, but with reference markings. The level is determined where a shift in marking is noticeable.

Sag Tester (DIN 55 677)
Wet film strips are applied to a steel panel and positioned vertically. The thickness of the thickest layer without sagging is measured as the flow index.

Testing principle Parallel strips of wet film are applied to a substrate using a special paint applicator frame made of stainless steel and featuring slots of various heights. The sag tendency is determined in a vertical flow test, the levelling tendency is ascertained when the specimen is horizontal. The specimen panel is examined visually after the coating has hardened. Levelling test according to ASTM D 28011) The wet film strips are applied to a predefined substrate using the doctor blade for levelling tests. After the specimen has hardened in the horizontal position, the number of double...

The four drawing blades of the film applicator frame feature a total of 24 slots (s. fig. 2). As in the case of Model 419-ASTM, the slot width and the distance between the slots is predetermined. The slot heights vary between 75 pm and 1300 pm. The strips of wet film are applied, preferably to a standard specimen panel made of steel. Subsequent to application, the specimen panel is positioned vertically (film strips running across the panel with the thinnest strip uppermost) and the coating allowed to dry. A suitable thickness gauge is used to determine the thickness of the thickest layer where...
