Grupo Prolutec is a group of companies in the chemical sector that manufacture smart synthetic products and offer maintenance services to all areas of industry.

We have four specialist divisions Eurolube, Dogus and Nautral – which share a common denominator: quality and customer service. These divisions work in the fields of lubricants, coatings (paints and inks), detergents, disinfectants and facilities and machine management.

We strive to innovate and aim to create a new generation of more reliable products that satisfy our client’s specific needs and requirements with more features, new functions and more effective, sustainable uses and applications. For this reason, smart products are at the heart of our business strategy as their performance will match client specifications.

We treat every new project as a custom project.. Although we manufacture a wide portfolio of effective products, our solution to any new challenge facing a client is always based on an improvement proposal, and our work process is divided into four stages::


We study and document the client’s current situation and come to an agreement on the improvements and value our project will bring to their company.


We present the Grupo Prolutec proposal, which establishes the project goals and desired results.


Next, we define a series of indicators that will allow us to both demonstrate that the project targets have been reached and measure the success of our solutions.


Finally, our relationship with the client does not end there: we offer our clients peace of mind after the project is completed by monitoring the indicators to ensure the agreed results are maintained over time.

This meticulous work process guarantees that every Grupo Prolutec project is a success. We make sure that we have a clear understanding of our clients’ objectives and guarantee the agreed results are achieved.
