For testing the surface tension
To determine the cleanliness of surfaces
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 mN/m (dyne/cm).

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
Rapidtest 38® serves to check if the treatment of polyolefins (polypropylene, polyethylene, polybutylene) has shown an effect onto the material.
- extremely easy to handle
- perfect for quick checks on polyolefins
- no wiping off necessary
- lasting display of result
- archiving of the image possible

Check metal surfaces for cleanliness
In this application example, is tested with test ink PINK from 10 ml bottles with cotton swabs. Take a new cotton swab after each use.
Testing a polyolefin film to 38 mN/m
RAPIDTEST 38® serves to check if the treatment of polyolefins (polypropylene, polyethylene, polybutylene) has shown an effect onto the material. A stroke of the pen leaves a full line on the material if the material´s surface tension has a value of 38 mN/m or more. If the material´s surface tension is below 38 mN/m, the fluid contained in the pen will form small drops on the surface. The fluid applied to the surface will dry within seconds, it doesn´t need to be wiped off anymore.
