SURFACE TENSION MEASUREMENT

Surface tension measurement helps ensure proper adhesion compatibility between inks, coatings and substrates. A wide range of products is available to help depending on the type, size and level of measurement needed. Surface tension is measured in Dynes/cm. To allow the best possible compatibility with inks to a substrate, the surface tension must be approximately the same as the substrate. To allow the printing and adherence of plastic substrates and other non-porous materials such as polymer, the surface must be treated so the surface tension rises to a defined point.

DYNE TESTING * DYNE PENS FOR GO-NO-GO

This alcohol based Polymer-Ink dyne pen is often used as a “treat/no treat” test pen on polyethylene and polypropylene film. Available with either blue or red ink, the non-cancerous dyne solution is very dark and more environmentally friendly than standard pens. Available only as a 38-40 range pen, it is intended for those who normally only use one pen (as opposed to those testing over a broad range).

DYNE TESTING * LIQUID DYNE PENS

The CON-TROL-CURE® Liquid Dyne Pen's spring-valve tip design keeps the pen's applicator away from the dyne fluid storage to prevent contamination. Press the tip firmly down to open the valve and flood the tip with fresh fluid. Available in sets of 8 pens from 30 to 44 dynes/cm (30, 32, 34, 36, 38, 40, 42, 44) and from 46 to 60 dynes/cm (46, 48, 50, 52, 54, 56, 58, 60); also available by special order at any level from 30-60 dynes/cm.

6 month shelf life.

DYNE TESTING * FELT TIP PENS - MARKER DYNE PENS

Measure printability of plastic substrates and other non-porous surfaces with CON-TROL-CURE® Felt Tip Dyne Pens. These chisel-tip markers provide a quick, clean and easy method of testing treatment levels on polymer plastics. The simple application of a dyne pen to the surface or printing side of the tested material will determine its surface tension value, which proves if the wettability of the pen's designated dyne level has been reached.

Once surface tension is known, the tested material's printability and adhesion properties may then be quantified. The Felt Tip Dyne Pens are tube color-coded for easy identification. Each set contains 8 pens in standard levels: 30, 32, 34, 36, 38, 40, 42, 44 dynes/cm. 6 month shelf life.

DYNE TESTING * DYNE TEST PEN SET 36-48

This 6 pen magic marker-type pen set quickly and effectively verifies whether a substrate is treated from 36 up to 48 dynes/cm. If the material is properly treated, the applied dyne mark is uniform, resulting in a continuous and homogenous colored line. If the material is insufficiently treated, the line of the dyne test retracts in the form of small globules until the mark nearly disappears. Set includes pens in 6 levels: 36, 38, 40, 42, 44 and 48 dynes/cm. 6 month shelf life.

DYNE TESTING * DYNE TEST SOLUTIONS 100cc

Dyne Test Solutions are another way printers, converters and extruders can determine surface energy levels. Ranging from 30-60 dynes/cm, these solutions offer an easy and effective method of testing. By wetting the tip of a cotton applicator with one of the mixtures and spreading a line over the test specimen, users can verify treatment within 2 seconds. If the continuous line holds for 2 seconds or more, users can be assured that the material is treated to within 1 dyne of that specific solution.

Continuing to test different levels in ascending order will allow the user to ultimately determine the appropriate level of treatment. If the continuous film breaks into droplets in less than 2 seconds, the material is insufficiently treated. Users must continue to test in a descending sequence to determine treatment level. Applicator must be changed after each test.

FEATURES:
• Wide variety of testing levels
• 30-60 dynes/cm
• Applies easily with cotton applicator
• 6 month shelf life
• Sold/100cc bottle

DYNE TESTING ACCESSORY * COTTON SWABS

Avoid contamination of your dyne liquid markers and liquid testers and your test area when performing dyne liquid markers, and liquid testing. Use these disposable, highly absorbent cotton swabs rather than the pen tip to mark substrates. Available in box of 1000.

GONIOMETER * SURFACE TENSION MEASUREMENT

The Pocket Goniometer is a battery operated instrument that measures static contact angle and dynamic surface hysteresis for laboratory and field applications related to gluing, printing and surface-related problems. It is an ideal tool for checking contamination of a specimen and the effects from cleaning and surface treatments.

By placing a liquid droplet on a specimen surface a contact angle is formed at the contact area. A droplet that "beads up" is non-wetting and a contact angle greater than 90° is displayed. When the droplet "wets out" across the surface, wetting is obtained and the contact angle is less than 90°.

A 6x magnified image of the droplet is displayed on the built-in screen. A reading is quickly made by rotating the protractor until the lines are parallel to the tangent at the contact point. An optional eye-piece provides 7x magnification of the test sample for very accurate readings.

FEATURES:
• Portable unit high quality lens system
• Battery operated long life light source (expected lifetime of 70,000 hours)
• Additional syringes are available separately
• Industry Standards: ASTM D724, TAPPI T458, SCAN P 18
