Dyne Test Pen is an economical, quick, and easy way to measure surface moisture or surface energy. The Diane test pen, sometimes known as the Corona test pen or Sherman pen, is a simple method of determining the surface energy of most polymer-based materials.
Dyne test solutions are often used to determine the surface energy level and cleanliness of substrates during plasma surface modification, corona surface treatment, and flame treatment, especially within industries such as packaging and converting, automotive, aerospace, medical device manufacturing In applications etc.,
Our Dyne Test Pens are equipped with valve tip applicators and do not suffer the inherent disadvantages of “magic marker” or “felt tip pen” types.
Quick and easy to use
To use the Dyne Test Pen on the surface of the material, the liquid will either form a continuous film on the surface or come back in droplets. If the dyne test fluid remains as a film for 3 seconds or more the material shall have the minimum surface energy (dyne level) in mn/m of the ink value. If the dyne test liquid shrinks back into droplets in less than 1 second then the surface energy of the substrate (dyne level) is less than the liquid value. The exact surface energy (dyne level) can be determined by applying a series of increasing or decreasing values to the Dyne test pen.
Dyne test pens are available in a range of values from 30 to 72 dynes/cm (Mn/m) and are supplied in disposable pens. The test fluid contained within the pen is ISO 8296 with extra high visibility dye for easy reading.
Dine Pen and Test Fluid – How do they work?
Dyne Testing is fast becoming the most well-known and trusted supplier of Dyne Test pens and inks for countless applications across the industry in New Delhi INDIA and overseas. Offering customers a choice of Diane testing solutions, Diane Testing strives to provide first-class, value-for-money products and services provided by a great team of caring people.
Achieving high surface energy is essential for optimum adhesion when printing, gluing or coating on various substrates. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues, and coatings. Surface energy can be easily determined using Surface Energy Test Pens and Inks (Dyne Level Testing).
Dyne test fluids perform well on most non-absorbent materials. It is important that the test fluid does not change the surface properties of the substrate. For example, if the test fluid penetrates a fiber substrate (such as paper) and causes swelling, the results will indicate unrealistically easy wetting. A chemical reaction between the test fluid and the substrate will completely invalidate the results.
When dyne-level test fluid is applied to a surface, the fluid either forms a continuous film on the surface or comes back as 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). Should the Dyne test liquid be reticulated or drawn back into droplets in less than 1 second, the surface energy of the substrate is less than that of the liquid. The exact surface energy (dyne level) can be determined by applying a series of increasing or decreasing values to the dyne test fluid.
The Dyne Pen supplied by Dyne Testing is based on the ISO 8296 method for measuring the surface energy of fluid polyethylene film contained within and provides a valve tip applicator type pen and not the “felt tip pen” type which is used for much more fluid generates. , Create more possible mistakes during testing. The Dyne test provides a range of Dyne levels between 30 – 72mN/m supplied either as a disposable pen or in bottles of test liquids.
Surface energy test Surface energy can be easily determined by pen or ink (Dyne level test) or by contact angle measurement. More information about these products can be found by visiting the product pages: Dyne Test Pen, Dyne Test Pen 38; Food Testing Ink, Drawdown Testing Equipment,
