Description
Test ink blue arcotest® 18 mN/m is a colourless surface-tension test fluid designed for low surface-energy evaluation on solid materials. Specified at 18 mN/m with a density of approximately 1 g/cm³, it helps determine whether a substrate will wet or repel a liquid film—information that is critical before coating, printing or bonding steps. A brush-applied film is observed for continuity or break-up, providing a fast, comparative reading of surface free energy in quality laboratories and production environments. The 10 ml pack is supplied with a brush for controlled application and economical use of the reagent. This arcotest® blue-series ink from manufacturer Arcotest suits plastics, polymer films and other technical surfaces where a defined low-tension reference is needed. Compact packaging supports straightforward storage and handling beside the process line or bench. Apply according to recognised test-ink methods and review the safety data sheet before first use.
This article is part of Test inks & surface tension, in Test kits & water analysis.

Questions about Test ink blue, arcotest® 18 mN/m (colourless), with brush, Density (D) ~1 g/cm³
What is this article?
Test ink blue, arcotest® 18 mN/m (colourless), with brush, Density (D) ~1 g/cm³ is the article on this page. Luminix Health distributes Arcotest for laboratory use. It sits in Test inks & surface tension, inside Test kits & water analysis, in Lab chemicals.
A test ink checks the surface energy of a solid: the ink either wets the surface or crawls back. The stated dyne value is the product. It is a surface-treatment check, used on plastics and films, not an assay of a liquid concentration.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
Which category should I open next?
The category is Test kits & water analysis. The sub-category is Test inks & surface tension. The catalogue is Lab chemicals.
Shelves beside this one are Cuvette tests (Nanocolor), Colorimetric test kits and Test strips & indicator papers.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
