LABORATORY DRAWDOWN
For accurate, repeatable applications of test coatings, the precision CON-TROL-CURE¢â
Laboratory Drawdown is an economical solution to many of the problems associated
with manual drawdowns. The unit controls the load on the drawdown rod with
a simple, weighted assembly and holds the rod securely during the drawdown
stroke. This operation eliminates human-related differences in rod pressure
and direction of stroke. Accurately make samples up to 12"W x 13"L.
The system is constructed with heavyduty ball bearing slides for reliable,
long-lasting use. The Laboratory Drawdown uses a standard 1/2" diameter
stainless steel bar that is tightly wound with stainless steel wire. The
diameter of the wire, in the wound form, regulates the thickness of the
coating. The bars are available in 45 different wire diameters from .0025"-.090"
(wet film thicknesses from .25-.9 mils). Bars are sold separately.
