A flexible and easy to use applicator, combining 4 gaps sizes in one unit. The cylindrical shape provides excellent results particularly on firm substrates and smooth surface. By simply rotation through 90 angles, the next gap size is placed onto the test surface. It is designed with ASTM D 823-25 and made of high-grade, corrosion-resistant stainless steel 440C.
Main Technical Parameters
■ Wet Film Width of:
BGD 205→160mm; BGD 206→80mm;
■ The total length: BGD 205→190mm; BGD 206→100mm;
All applicators are marked with gap clearance, this gap clearance isn’t wet film thickness. The theoretical wet film thickness is etched onto every applicator. Generally speaking:
◆ Gap clearance is from 15~100µm, the theoretical wet film thickness is 50% of gap clearance
◆ Gap clearance is from 100~300µm, the theoretical wet film thickness is 60% of gap clearance
◆ Gap clearance is from 300~500µm, the theoretical wet film thickness is 80% of gap clearance
◆ Gap clearance is more than 500µm, the theoretical wet film thickness can reach 90% of gap clearance
