Chimar Hellas S.A. is a Greek chemical company,[3][4][5] founded in 1978 under the name MARLIT by Greek chemist Effy Markessini and her husband, Andrew C. Markessini, which specializes in wood adhesive systems and related additives, providing also expertise and services as well as technical support for engineered wood products.

[6][7][8] In 1977, Andreas and Effy Markessini developed a patent for a new chemical product suitable for particleboards, resulting in lower costs for manufacturing plants and decrease in formaldehyde emissions.

Over the years, additional patents for adhesives were developed and the company entered into collaboration with the German manufacturer, Bison Werke Bähre und Greten.

[11][12] In 1994, the company under its new name, Chimar Hellas, began developing technologies for the production of formaldehyde-based resins such as UF, MUF, and PF.

Together with its subsidiaries MARLIT Ltd. and Adhesives Research Institute Ltd., the company laid the foundation for the ACM Wood Chemicals Plc corporate group.
