These wire-wound metering rods, when used on a precision surface such as the Diversified Drawdown Platform, will apply a highly uniform wet film thickness, which is ideal for dyne testing.

For dyne testing, we recommend using rods with #3 wire — these will meter the test fluid to a thickness of about .0003″ (0.3 mil, or 7.6 microns). Thinner fluid films are extremely difficult to maintain and see; thicker films will be less sensitive to purely surface effects.

These wire-wound metering rods, when used on a precision surface such as the “DyneX” Drawdown Platform, will apply a highly uniform wet film thickness, which is ideal for Dyne testing. The rods, widely known as Metering Rods, Mayer Rods or drawdown bars are fabricated from 303 stainless steel; the wire winding is 304 stainless steel.

The Mayer Rod Drawdown Method is an industry standard under TAPPI Test Method T 552: Determination of Wetting Tension of Polyolefin Films and Coated Surfaces via the Mayer Rod Technique. How to apply: A substrate sample, usually measuring 8-1/2 x …

All rods mfd. 303 SS rod with 304 SS wire unless otherwise requested. ACCU DYNE TEST™ surface tension test fluids are formulated per ASTM Standard D2578 from 100% reagent grade materials, and each batch is tensiometer tested to assure consistent results. Learn more at …

direct benchtop testing a reality. For best results, we strongly suggest use on a “DyneX” drawdown platform. All four gates are precision ground to the same clearance to facilitate quicker test-to-test turnaround, and to provide the longest service life. …

Feb 18, 2021 · The accepted methods to determine the level of energy on the substrate are Dyne Test, Contact Angle and Tape Test. The most common of these test methods employs an indicator solution, known as dyne solution, applied to the surface of the treated substrate.

Dyne testing is a technique that assesses the wetting tension of a solid by applying a liquid with a known surface tension to its surface. This measurement, expressed in dynes per centimeter (dynes/cm), approximates the force required to spread a fluid across the material's surface.

Dyne Solutions Dyne Accessories Jemmco offers a full line of equipment and supplies for film extruders and web converters.

Determining the surface energy can be achieved by measuring contact angle or by use of Surface Energy Test Liquids or Pens (Dyne level testing). Dyne test inks and fluids (sometimes referred to as corona test fluids) are used for the quick and easy measurement of …
