Dyne Test Inks and Dyne Test Pens
For testing the surface tension.
To determine the cleanliness
of surfaces.
Dyne Test Inks can make statements on the adhesive strength of printing inks, coatings and adhesives on all surfaces such as plastic, metal and glass as well as on the degree of cleanliness in dyne/cm (mN/m).
RAPIDTEST 38® Jumbo refillable
Our RAPIDTEST 38® makes it easy to test the surface tension of pre-treated plastics. The RAPIDTEST 38® enables very precise testing of the surface tension after pre-treatment of plastics such as PP and PE.

• Not harmful to health
The RAPIDTEST 38® is a particularly easy-to-use test device that has proven itself in daily use by manufacturers of films and moulded parts.
The RAPIDTEST 38® test ink is suitable for corona, plasma and flame testing.
A treatment can be recognised immediately by a closed colour stroke; necessary corrections to the pre-treatment can be deduced from the beading of the test ink.
arcospray® 38
The arcospray® 38 test ink is a test liquid with a surface tension of 38 dyne/cm. It has been designed to quickly detect whether the surface is grease-free, as values equal or greater than that mean freedom from grease. After its application, arcospray® 38 can be removed without residue using oil-free clean blower air (compressed air).
Tested parts can be used further.
Not only large areas, but also very small areas, such as chain links, can be assessed quickly and easily by the arcospray® 38.

arcotestCLEANER
is a solution based on ethyl alcohol. It serves to improve cleanliness on various surfaces such as metals, glass and plastics. With the arcotestCLEANER also tested parts can be reused by wiping off the test ink. As the surfaces formulations are very different, a suitability test should be carried out before each application.
• better cleanliness due to surface cleaning
• Solvent system based on ethyl alcohol
• no unpleasant odour
• dries very quickly
• can clean and possibly increase adhesion-strength in one step
• increase adhesion strength
• easy cleaning of the applied test inks
• available in 250 ml aluminium bottles

Testing of a polyolefin film for 38 dyne/cm
RAPIDTEST 38® serves to check if the treatment of polyolefins has shown an effect onto the material. A stroke of the pen leaves a full line on thematerial if thematerial’s surface tension has a value of 38 dyne/cm or more. The fluid applied to the surface will dry within seconds, it does not need to be wiped off anymore.
