Harmful chemicals when burnt can create a toxic environment for people and the ecosystem.

Methyl Ethyl Ketone (MEK)

Dangerous substance when in contact with your colleagues, causing irritation and damage to skin and eyes.


Halogens are group 17 of the periodic table, comprising Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I), and Astatine (At). Of these, chlorine and bromine are the most common.

Most halogens when burnt, for example at the end of the product’s lifecycle, emit chemicals that can be harmful, as they can create toxic and corrosive gases in the environment.

The International Electrochemical Commission (IEC) set the standard for what halogen-free means, IEC 61249-2-21:2003:

  • Chlorine ≤ 900 ppm
  • Bromine ≤ 900 ppm
  • Total Halogens ≤ 1500 ppm

Our halogen-free inks meet these standards

MEK (Methyl Ethyl Ketone)

MEK (Methyl Ethyl Ketone), also known as 2-butanone, is a colourless, volatile, highly flammable liquid with a fruity odour similar to acetone. MEK is used in largely in industrial settings for a number of uses, particularly as a solvent for inks and adhesives.  

Unlike halogens, MEK does not build up in the environment, however it can have adverse effects for those who are exposed to it regularly for long periods. MEK in the air can cause irritation of the skin, eye, nose, and throat and may cause chest tightness.

For those using MEK inks in their workspace will be required to have policies in place to keep their workers safe.

Linx offer a number of MEK-free inks which great adhesion and clarity. Read our blog here.
