To ensure a productive painting system without quality issues, it is necessary to keep the system clean and stable. This can only be achieved through a combination of technically sound chemicals, supplier support, and technical assistance from paint shop personnel.
It is not possible for the excess paint generated during painting application (overspray) to be captured solely by water. Therefore, the washing system inside the booth must contain paint-killing and curing chemicals. When the overspray comes into contact with water, it reacts with the chemical, causing it to lose all its properties and then be removed from the booth water and system. This prevents blockages and disturbances in the washing system of the booth and thus maintains air balance.
The direct and indirect consequences of not using chemicals or using the wrong products in wet painting systems are as follows:
- The washing system splashing water onto the painted or to-be-painted part due to paint sludge (water coming from the water curtain to the part),
- The paint booth not being able to exhaust properly, leading to the interior of the booth being covered with paint dust during production (quality issue),
- Paint particles entering the exhaust fan causing imbalance and paint accumulation on the fan blades, which can lead to a fire due to static electricity on the fan blades.

Manual Cleaning is Disadvantageous
On the other hand, the absence of chemical use and/or the use of inefficient products in water-filtration paint booths will lead to an increasing need for manual cleaning, which will become a constant requirement. Manual cleaning processes are risky in terms of both work and worker health, and they never provide the opportunity for complete cleaning of the booth (such as water circulation systems and air ducts). The greatest burden of manual cleaning will be on labor costs as well as production downtime."

Worker Health and Safety Are Affected
Another consequence of not using chemicals or using the correct products in water-filtration paint booths is the saturation of solid matter in the water used in the booth, resulting from paint sludge and the use of inefficient chemicals, leading to the end of its lifespan and the formation of bacteria inside, causing odor and posing risks to work and worker health. This inevitably increases wastewater costs.

Additional Burdens Are Eliminated
Evakim’s cogulation and flocculation products (on the left) prevents the water from being consumed by aerating it due to its chemical structure, thus preventing the formation of bacteria. More importantly, since the product’s solid content is less than 1%, it does not contribute to the amount of paint sludge to be removed from the system, thereby avoiding additional costs for paint sludge disposal. This eliminates the need for water replacement in the system.
