For optimum adhesion when printing, gluing or coating on various substrates, it is necessary to obtain a high surface energy. 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 surface energy or wetting tension. This form of measurement is based on ISO8296 that describes the method for measuring the surface energy of polyethylene film. Using the Dyne test liquid gives quick and easy results indicating surface wettability. The low surface energy of polymer-based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Surface Treatment with either Plasma or Corona results in good wetting of the material over the surface of the substrate and so improves adhesion.
We have many customers in the UK & overseas who use our Dyne Test Fluids to test metal products for surface cleanliness and evaluating the characteristics of their products also. The surface energy of metals is much higher than that of most surface contaminants thus, the higher the Dyne level or surface energy (mN/m) also the cleaner the part is.
To use the corona test fluids simply apply the Dyne test fluid to the material surface, the liquid will either form a continuous film on the surface or draw back into droplets. If the Dyne test ink remains as a film for 3 seconds or more then the material will have a minimum surface energy (Dyne level) in mN/m of that fluid value. Should the Dyne test liquid draw back into droplets in under 1 second then the surface energy (Dyne level) of the substrate is lower than that of the liquid value. The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test fluids.
The test fluids can be purchased as a kit holding 6 bottles or as individual bottles. The test inks come in 20ml bottles and have an expected lifetime of 12 months.
ISO Type (to ISO 8296):- Formamide & 2-Ethoxyethanol based:
Supplied in 20ml bottles with integral brush applicator, containing: formamide, ethoxyethanol & dye, not suitable for use on soft PVC.
Non-Toxic range of Ethanol based Dyne Test Inks.
Supplied in 20ml bottles with integral brush applicator, containing: ethanol – not suitable for use on PP.
Cotton Applicator Swabs – Made to test method ISO 8296 for use with the Dyne test fluids. The cotton swabs have a 150mm long shaft to ensure your hand is kept well away from the test fluid and the substrate to be tested. The cotton applicator swabs are binder free and glue free which ensure the binder or glue cannot contaminate the test fluid or invalidate the test results.
Ensure that no contamination is introduced into the Dyne test fluid from the surface being tested by using a single use cotton applicator swab. Small amounts of introduced contamination may lead to inaccurate and invalid Dyne level readings.
Features & Benefits
- Instant results (within 3 seconds)
- Avoids cross-contamination when used with single-use cotton applicator swabs
- Can be used on a wide variety of substrates
