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.

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 of a polyolefin film for 38mN/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 thematerial if thematerial’s surface tension has a value of 38mN/m or more. The fluid applied to the surface will dry within seconds, it does not need to be wiped off anymore.
