Designed according to ASTM D2801 standard, the groove depth range is 0.1-4 mm, which can test the leveling and sagging of coatings for rapid formulation adjustment and qualification verification.
Designed with 90mm application width and 25μm Graduation, with removable guide plate to ensure direct stretching, the sagging index is assessed through 10 aliquots, meeting ASTM standards.
The black and white stripe design is easy to observe the levelling effect, the specification 194x289mm meets the ASTM standard, has excellent solvent resistance and dimensional stability, and does not deform or curl in the humidity environment.
The total film width of 90mm is divided into 10 gaps, the depth is gradually increased by 25μm, and the spacing is 1.5mm. The removable guide plate design is easy to operate on different thickness test panels.
The 90mm total film width is divided into 10 equal gaps, the depth is increased by 25μm, and the removable guide plate is equipped to ensure direct stretching on the Glass or thick test panel, which meets the requirements of ASTM standards.
The device provides 450-1000 μm film thickness test range, Graduation 50/100 μm, equipped with 10 grooves, can accurately simulate the vertical top coating film sagging behavior, ensuring stable and reliable test conditions.
Using stainless steel material, film thickness range 850~ 1075 microns, groove difference of 25 microns, in line with GB/T9264 standard, suitable for on-site determination of Paints sagging, Dimension 120 * 22 * 20 mm.
S136 stainless steel material, corrosion resistance and high Hardness, film thickness range of 450~ 675 μ m, Spreader width of 73.5mm, suitable for multi-range testing, clear scale easy to observe sagging phenomenon.
