Cleanrooms are essential components of advanced manufacturing facilities, ensuring precise production of materials and technologies. From pharmaceutical manufacturing to aerospace manufacturing, and critical pieces of technology like semiconductor chips, cleanrooms have a significant role in ensuring the contamination-free production of these materials.

Semiconductor chip manufacturing is a great example of a rapidly evolving and critical piece of technology that relies on the stringent operations at a much larger scale with clean zones that span from modular cleanrooms to multiple levels that can span up to several hundred thousand square feet. 

Semiconductor chips are manufactured in facilities called fabrication plants (or fabs for short) and housed on massive campuses that span acres. The entirety of a fab is built to an exacting standard, and every detail, down to the choice of flooring systems, contributes to overall efficiency and performance. 

Chemicals such as solvents and acids are used in the wafer production process which can corrode steel and concrete substrates

Flooring systems specified for fabs, typically referred to as chemical-resistant coatings, often go unnoticed but play a vital role in structural protection, contamination control, durability, and the overall production efficiency of a fab.

Developing chemical-resistant coating systems to meet the requirements of a semiconductor fab ensures clean zones continue to support rapid innovation and production demands while minimising maintenance downtime.
