How does a dyne test work?
How does a dyne test work?
When the Dyne level test fluid is applied to the surface, the liquid will either form a continuous film on the surface or pull back into small droplets. If the Dyne test fluid remains as a film for 3 seconds, the substrate will have a minimum surface energy of that ink value, expressed in mN/m (Dynes).
How do I check my dyne level?
A technician can choose from three methods to measure a dyne; a dyne pen, draw-down, or swab applicator. The most common method of testing is with the dyne pen. If surface tension of the dyne liquid is higher than the surface energy of the substrate, the liquid will begin to form small water particles.
What is a dyne test pen?
Dyne Test Pens are a cost effective, quick and easy method to measure surface wetting or surface energy. Sometimes known as corona test pens or sherman pens the Dyne Test Pen is a simple method of determining the surface energy of most polymer based materials.
What is the use of dyne?
A dyne is a unit of measurement used to measure force. Dyne per centimeter is the unit used to measure surface tension of liquids. Surface tension is a suitable way to estimate the surface energy of a material, which is an excellent indicator of adhesion failure or success.
How do I increase my dyne level?
One of the most common ways to raise the dyne level of the substrate is by corona discharge treatment. This is optimally done on press, just before the printing units. The surface of the film is exposed to an electrical discharge, which oxidizes the film surface.
What is dyne value?
A dyne level is the measure of surface energy. The more surface energy or higher dyne level a surface has, the better paints and glue will adhere to it. Dyne levels are an important measure for the automotive industry as well as in the fabrication of plastics.
What is corona treatment in printing?
A corona treating system is designed to increase the surface energy of plastic films, foils and paper in order to allow improved wettability and adhesion of inks, coatings and adhesives. As a result, the materials treated will demonstrate improved printing and coating quality, and stronger lamination strength.
How long do dyne pens last?
Some users replace their Dyne pens every 4-6 months, some prefer to replenish as frequently as every month (a couple customers actually get deliveries every 2 weeks!). Our general recommendation is that if the Dyne test is a critical quality parameter in your business then you should replace your pens every 3 months.
Does dyne go bad?
The bottle I have previously purchased does not have an expiration date. The expiration is normally pushed out a year. We’d recommend storing in a cool, dry place for best results.
Is dyne a unit of weight?
Therefore, the SI unit of weight can be measured in kg⋅m/s2 (kilograms times meters per second squared) which is equal to a newton (N)….SI Unit of Weight.

How long does flame treatment last?
A Flame Treating process consists of exposing the surface to a suitable oxidizing flame for a period in the range 0.2 to 3.0 seconds.
What is Dyne testing and how does it work?
In many instances, dyne testing is a mechanism to check for the presence of treatment rather than check specific levels of treatment. This precipitated the further development of another pen that is alcohol based, quick drying and really meant as a go, no-go test pen for “on the fly” type testing.
What is a dxdyne test pen?
Dyne Test Pens are a convenient means of verifying a substrate’s treat level. They are commonly used in applications as a quick reference, when the accuracy of dyne solutions is not needed or where dyne solutions are not convenient to use. It is for this reason; dyne pen use is most often used at the production line or in the field.
Why choose dynamicdyne Testing Ltd?
Dyne Testing Ltd is the leading UK manufacturer and supplier of quality inspection test instruments to measure the surface properties of both solids and liquids.
How does a Dyne pen work?
Also known as dyne pens, these work like a felt-tip marker. A continuous line will appear if the material meets the tester’s surface energy level, while insufficiently treated material results in air bubbles and a disappearing mark.
