International. PPG's Green Logic paint remover is a chitosan/aluminum salt-based liquid paint denaturant that provides an environmentally responsible alternative to traditional melamine-formaldehyde and acrylic acid-based chemicals.
Paint denaturants, also known as "paint removers," are added to the water curtain circulating in water-washed paint spray booths to make the oversprayed paint non-sticky.
In traditional automotive OEM wet paint spraying operations, only 50% to 80% of the paint is transferred to the vehicle, and the remaining 20% to 50% is carried in the cabin airstream and then removed by the circulating water curtain.
Paint denaturants are added to the water curtain to remove stickiness, coagulate and flocculate this sprayed paint, allowing it to be removed from the water in a continuous or batch process.
Most nonstick suppliers have been using melamine-formaldehyde-based nonsticks, which necessarily contain small amounts of residual free formaldehyde.
The group of acrylic acid-based paint denaturants is originally derived from ethylene and/or propylene produced during the petroleum cracking process and therefore depends on non-renewable petroleum-based raw materials.
The unique feature of the Green Logic paint remover is that it is derived from crab, lobster and shrimp shells, which are natural waste products of food production.
Green Logic paint remover has been singled out by OEM users as "best in class" and nominated for numerous environmental awards.
This recognition has been driven by performance gains made not only in paint removal, but also in the overall operation of the paint booth.
The benefits to automakers are increased ease of operation and overall system cost savings that are attributable to lower maintenance costs for paint booths, biocides, and wastewater treatment.
In addition, the paint sludge generated by the use of Green Logic paint remover is more prone to biodegradation.
