DRAWDOWNS : FILM THICKNESS CONTROLS

Determining a desirable film thickness requires understanding of how a wet film reacts at various thicknesses. Viscosity, surface tension and other physical properties that affect the final result must be understood before establishing what thickness will be accepted for a particular production. UV Process Supply offers many different tools for helping you determine these characteristics.

8 PATH SCRAPER DRAWDOWN

This chrome applicator features 8 precision channels ranging from 1 mil to 8 mils. A small quantity of the material to be checked is placed on the inside of the selected channel and drawn down over a paper chart or other smooth flat surface providing a uniform thickness of film for observation and testing.

BLADE APPLICATOR GAUGE

The Blade Applicator Gauge combines the accuracy of a "bird" type applicator with the ease of thumbscrew adjustability. It is specially designed to provide precise test samples of inks, paints, coatings and adhesives. The shape of the applicator blade is not a sharp knife edge, but a flat area. Through a shearing action only half the liquid is deposited on the test sample. The applicator lays down a wet film thickness which is nominally one-half the gap clearance.

To operate, loosen each knob, slide the calibrated plate to the desired gap setting, and retighten the knobs. Drawing the applicator across a pool of coating liquid allows the precise gap at the blade to produce a wet film of the required thickness.

DRAWDOWN BARS / RODS - WIREWOUND RODS

These rods give users the ability to fine-tune coating thickness quickly and easily, without altering the chemistry of their coating material, and without time-consuming and expensive changeovers.

For users that require a coating path of up to 12", use the standard Laboratory Drawdown Rods (N008-005 choose 1/4", 3/8", or 1/2") . With an overall length of 16", these rods are longer than the Jr. variety.

The Accu-Lab Jr. Laboratory Drawdown Rods (N008-026, N008-026A) are designed for users producing test samples up to 8½" wide. These stainless steel rods are 4" shorter than conventional lab rods and offer an additional savings.

Wet coating thickness can be accurately predicted within one tenth of a mil (.0001"). Rod selection tables allow coaters to consider coat weight and percent of solids in choosing the proper rod size for each production run.

Bottom-line profits have encouraged many coaters to modify existing machines, in order to take advantage of the flexibility, the ease of use and the dollar savings associated with rod coating.

The market for wire-wound rods has grown rapidly during the past few decades, because they provide predictable, accurate coatings time after time, at a minimal cost. Although the technology goes back almost a century, today's high quality materials, multi-wire designs and special wire surfaces have made this system more popular than ever before.

Wire-wound rods were first used in coating machines built by Charles Mayer in the 1900's to manufacture waxed paper and carbon paper. They are still called "Mayer Bars" by many coaters.

Standard Lab Rods (N008-056, 057 & 058) are less expensive due to a different manufacturing process and all of these are 16" long with a centered wound length of 12".

ROD SIZE NOTES:
To determine approximate wet film thickness in Mils for a specific rod number from the table below, multiply the rod number by 0.10. For example, the number 3 rod would be 3 x 0.10 = 0.30 Mils. The number 20 rod would be 20 x 0.10 = 2.0 Mils.

For Microns, multiply rod number by 2.54. For example the number 3 rod would be 3 x 2.54 = 7.62 Microns.

HANDHELD DRAWDOWN FOR LABORATORY USE

The CON-TROL-CURE™ Handheld Drawdown is a low cost precision drawdown tool for testing inks, paints, emulsions, adhesives and chemicals in the laboratory, on the plant floor or in the field. The heavy-duty stainless steel construction will not rust or corrode and can be completely submersed in solvent for easy clean-up. Quick one hand operation provides a full 5" wide drawdown path of controlled coating thickness. Easy to change Drawdown Rods are available to produce coatings from .25 mils (.00025") using the number 2.5 rod to 9 mils (.009") thick using the number 90 rod. Includes 1 drawdown rod of your choice in that range.

AVAILABLE HANDHELD DRAWDOWN ROD WIRE SIZES

For a film thickness greater than 9 mils, custom double a triple wound rods are available at an additional cost. Please contact us for a custom quotation.

UV FLEXO INK HAND PROOFER

Precision Tools for Matching Color and Coatings

Finally, a quick and precise way to reliably match PMS and custom colors for UV Flexo, and Primographic inks off-press. After relentless hours of research and much time testing the ultimate way to match color, we finally found what we believe is the ultimate precision color matching tool. Each of the below hand proofers is sold with 1 anilox roll of your choosing (see the table at bottom.) If more rolls are needed please contact us.

With these UV Flexo Hand Proofers, you can go to press with an anilox/ink combination that delivers the precise color you need. Commercially compatible color proofing for both customer color approval, and spectraphotometer readings.

These industry leading units are compatible with solvent based systems, ensuring a minimal clean-up. The easy take down design allows for quick and easy changing of the engraved anilox rolls. The anilox rolls are platinum laser engraved. The Doctor Blade loads the celIs of the anilox rolls and meters the ink to a repeatable ink film thickness.

The Traditional Echocel Junior is a Flexographic hand proofing system incorporating Platinum® laser engraved ceramic anilox technology, steel doctor blade and solvent resistant rubber roll. This system has benefited from years of successful exposure in the field. Designed specifically for water based and solvent inks, this lightweight unit is the standard in the field. Ink path width is 2.75 inch (70mm) Traditional Rolls are engraved at a 60º Hex.

Our newest model, the Phantom Proofer, is the ultimate proofer to increase pressroom efficiency! Manufactured with many of the same quality components and high standards as the Echocel Junior, this unit improves upon that design. Its quick change anilox roll mechanism and doctor blade allow for easier clean up, increasing efficiency. The ultra lightweight design features less replacement parts and built-in bearings. Ink path width is 2.75 inch (70mm)

LABORATORY DRAWDOWN MACHINE

For accurate, repeatable applications of test coatings, the precision CON-TROL-CURE™ 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 (30.5 cm x 33 cm).

The system is constructed with heavy-duty ball bearing slides for reliable, long-lasting use. The Laboratory Drawdown uses a standard 1/2" (1.27 cm) 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.

The unit features:

Coating Thickness Chart located on the machine for easy reference.
Flat precision-polished plate glass drawdown surface.
Heavy-duty ball bearing slides.
Uses standard ½" Laboratory Rods available.

Easy to operate
Laboratory Drawdown Machine is easy to operate.
(a) Select the ideal rod size from the coating thickness chart and snap the rod into the weight arms.
(b) Mount your substrate sample on the glass surface and lower the weight arm assembly.
(c) Spread your coating liquid near the rod and pull the handle with a smooth, even stroke.
That's all you need to make consistent, repeatable precision test samples.
