GD 225 Sagging Tester produced by our company is in accordance with the specification of ASTM D4400 and ASTM D3730. They are made of corrosion-resistant stainless steel. The width of application is 75 mm at 6 mm per sagging thickness, with the gaps being separated by a 1 mm space as a marking on each sagging for distinctive identifications.
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 in site.
