Chemistry with Responsibility We live in a time of constant change and we at HSO adapt to it permanently. We produce innovative special chemicals for the plating industry, and it is not without reason, that we rank as one of the most important companies in the field of Plating on Plastics/Automotive worldwide. HSO was founded more than 80 years ago in Solingen, one of the very few still familiy-run companies of this branch of industry – and this already in the 4th generation. Besides the main site in Solingen, there are also two subsidiary companies in Brazil and China under the umbrella of HSO International GmbH as well as over 29 distributors worldwide. HSO stands for quick decisions and customer-adapted, innovative processes. We count on the thrust of our innovations, sustainability, personal contact to our customers and, thus, close customer relationships. The whole HSO team works together according to the motto „Working Together to Win“ to push the success of the company further ahead. The focus is on the lasting generation of values and profitable growth. A development, which we owe to the commitment of our staff, our distributors, suppliers and, of course, our customers.
