Prior to installation of this control system,
approximately 40% of all coating thickness tests were
outside of the desired
operating range. Now, less than 10% are out of the
desired range. Since startup 18 months ago, there has
been no maintenance of any of the instrumentation. The
entire system was purchased and installed for under
$5,000.

Why control viscosity? Accurate viscosity control can
reduce expenditures significantly in coating operations.
Industry always attempts to reduce operation costs, so
let's see how viscosity control helps. Until recently —
perhaps the last 10 years — viscosity control was not
given much attention in coating operations. Increased
competition and higher costs of materials have caused
many industrial concerns to utilize viscosity regulating
devices to reduce costs. This is especially true of
companies with a large volume of coating operations.

A number of industrial process fluids require
maintainence of optimum solids content to produce
uniform coatings. The manufacture of integrated circuits
and printed circuit
boards in the electronic industry present a number of
examples:
Photo resist coatings
Resins for fiberglass impregnation
Solder Flux for wave soldering
Application of conformal coatings
Similarly in industrial finishing the coating
thickness of paint or other material is heavily
dependent on maintaining optimum solids content.

A firm in Mississippi tested and then purchased a
M8BO Norcrorss viscosity control system. Their
evaluation is displayed in the graph below and they
remarked that they saw improved quality and consistency.

Precise control of the viscosity of paint to decorate
Ford automotive grilles has improved appearance and
durability while keeping paint costs down and production
rates up.
Chrome-plated grilles for the Crown Victoria,
Thunderbird, LTD and Grand Marquis are coated at Ford’s
Plastics Paint and Vinyl Div. plant in Saline MI in
automatic dipping machines manufactured by Deco Tools
Canada, Ltd. Each machine is equipped with a Norcross
viscometer, which keeps paint at the specified viscosity
automatically by adding small volumes of solvent as
needed.

Automatic viscosity controllers are helping
Westinghouse Electric Corporation meet customer
requirements for high quality laminated circuit boards.
Built for the company’s Specialty Materials and Copper
Laminates Divisions, the controllers replace
time-consuming and imprecise, manual control techniques
on seven fiberglass cloth treating lines at plants in
Hampton and Pendleton, South Carolina. The newest
controller, a microprocessor-based system, was recently
installed at Hampton, bringing the total number at that
plant to five.

The Horning Wire Corporation of Lake Zurich, IL,
manufactures magnet, appliance, bare and tinned wire and
has for the past 27 years used Norcross viscosity
controls.
According to Plant Supervisor Ted Caudill, “The initial
and continued use of viscosity controls was instrumental
in making Horning more competitive and viable in a time
when many wire coaters were forced to close their doors.
The early controlling of wire enamel viscosity was one
of the keys in Horning Wire’s success.”
