About Aarolac AG
Aarolac AG is an independent Swiss paint and coatings manufacturer based in Oberentfelden in the canton of Aargau. Founded in 1850 as Landolt & CIE. in Aarau, the company develops and produces in Switzerland coating systems for construction paints, corrosion protection according to DIN EN ISO 12944-5 (C2 to C5 very high), industrial coatings, road markings (AAROSTRADA-LINE) as well as wood coating systems for the window industry. The product range includes water-thinnable hydro paints (1K/2K), Minergie-Eco-compatible products, high-solid and conventional systems for substrates such as steel, iron, cast iron, galvanized surfaces, non-ferrous metals, plastics and wood-based materials. Plant II exclusively produces water-thinnable product lines; around 70 percent of annual production is water-thinnable. Distribution is via technical sales consultants and paint retailers, supplemented by application technology, seminars and plant and construction site services.

Quality and Environment
In Application Technology I and II, products are tested, inspected and approved before market launch during development; in the spray booth, the systems are applied and optimized with various spray equipment. The hydro paints are assessed with the environmental label of the Swiss Paint Foundation and meet the requirements of Minergie Eco.
