K170 is typically engineered to run at higher viscosity, which helps form a thicker, more uniform film and reduces runoff on vertical or rough surfaces. That can improve waterproofing build or certain maintenance coats, but it increases pumping load, raises clogging risk, and narrows the spray window. Higher viscosity can also slow water release, so curing time may be longer in cool or humid weather. Compared with lower viscosity grades, K170 demands better filtration, tighter temperature control, and more careful nozzle sizing and calibration.
