Wash coating: limiting hazardous substances and pollution efficiently
Many processes inevitably cause a chemical reaction that creates hazardous substances or results in pollution. With certain techniques, you can turn these substances into non-toxic gases. VITO, for instance, has years of experience with wash coating.
What is wash coating?
Wash coating is a technique that deposits active powders (slurry) onto structured supports. This leads to a coating that acts as a catalyst. If a substance comes into contact with that coating, the chemical properties of that substance are altered.
A common example is the production of catalysts for diesel exhausts by wash coating ceramic honeycombs. The substances in the coating react to harmful emissions and convert them into non-toxic gases like water vapour. We apply wash coatings onto other supports in a similar way, for various applications.
VITO leading the way
Thinking about integrating wash coating into your processes or do you have a plan already? VITO is here to help, every step of the way. We can:
- assess the techno-economic feasibility of your project.;
- offer advice on selecting the right starting materials and porous substrates;
- design and construct customised wash-coating installations at lab and pilot scale;
- develop customised wash coating processes using tailor-made protocols;
- help you develop procedures for process follow-up and quality control;
- wash coat newly developed products in small batches for evaluation by you and your clients;
- help you scale up the project within your own production environment or at a selected job coater providing you with the required technology transfer.

Wash coating: FAQ
Wash coating is for anyone who wants to deposit a catalyst or active powder on a porous support with a specific charge. When developing a new product or optimising an existing process, for instance.
