Universal Blade Applicators
These tools can apply either a constant or a continuously
variable wet film wedge from 0 to approximately half of the
maximum blade depth
from Paul N. Gardner Co., Inc.
(U.S. Patent #4,869,200)
This applicator design offers one of the most accurate and reproducible
ways to apply coatings to flat surfaces; it will enable you to determine the optimum wet film thickness for each application. Since most coating properties
are thickness-dependent, it is imperative that an optimum thickness
be determined for each application. The continuous thickness gradient
produced by these tools is ideal for hiding power evalution; it
can also be used to test coating flexibility, tack strength, spreading
rate, fineness of grind, and other coating attributes.
With both side plates adjusted to the same depth, a uniform coating
is produced; to create a wedge-shaped swath, set one end plate
to double the maximum wet film thickness desired, while the other
plate is similarly set to double the minimum thickness desired
(like all blade type applicators, the ratio of blade clearance
to wet film thickness may vary somewhat, being affected by drawdown
rate, as well as coating rheology and surface tension – on
the average, the ratio is about 2:1)
