BGD 225 Sagging Tester produced by our company is in accordance with the specification of GB/T 9264 and ASTM D 3730They are made of corrosion resistant stainless steel, the width of application is 75mm at 6mm per sagging thickness, and the gaps are being separated by a 1mm space as a marking on each sagging for distinctive identification of each sagging.
They are applicable to determine the relative sag resistance of a series of paints in order to provide the technical parameters for the paint application on site.
Material: Corrosion resistance of stainless steel
Difference between adjacent two notches: 25μm
Overall dimension:120×20×20mm(length by width by height)
The applicator can scrape 10 pcs of Parallel to the wet film in different thickness, the width of wet film is 6mm, space of each film is 1.5mm, thickness difference between adjacent film is 25μm
Drawdown the coatings on a material(glass, test chart or board)using the appropriates sagging Thickness Gauges, then place the coated material at vertical position(90º)to the platform(eg: table).Allow 10 to 30 minutes(depending on the viscosity)for the coatings to sag under gravity. Check out the coating thickness without the sagging effect and the next coating thickness with the sagging effect. With that information, the recommended coating thickness is between the 2 layers of coatings.
Suitable industries: Wet film test such as paints, printing ink, etc...
