Test inks can provide information about the adhesive strength of printing inks, paints and adhesives on all surfaces such as plastic, metal and glass and about the degree of cleanliness in mN/m (dyne/cm).

The arcotest^® ORGANIC test inks are test liquids with a defined surface tension that are coloured. They have been specially developed to offer non-toxic and non-labelling inks. The application and handling of arcotest^® ORGANIC is based on DIN 53364 and ISO 8296. Result: If the edges of the cotton swab or pencil application contract within 2 seconds, repeat the measurement with the next lowest value. If the edges run outwards, repeat the measurement with the next highest value. The surface tension is reached when the line remains in place for just 2 seconds.

Shelf life 1 year unopened, 6 months after opening. Individual components of the test inks evaporate to varying degrees. Close bottles and pens tightly after use.

Optimal for testing large areas
