Detackifier
A detackifier is a process chemical that is reducing tackiness of other substances. Spraying paint and paper making are processes where inputs may need to be detackified or "denatured".
==Spray painting==
Spray painting with solvent based or water based paint creates paint overspray, a waste material that must be effectively neutralized, or "detackified", and collected for disposal. In order to assist in the removal of the oversprayed paint from the air and to provide efficient operation of the down-draft, water-washed paint spray booths utilize paint detackifying chemical agents. The detackification products are commonly introduced into the water that is recirculated in the paint spray booth system. The first purpose is to render the paint non tacky so it doesn’t stick to the booth equipment and foul the paint system. The second purpose is to efficiently collect the paint solids that were sprayed into the system and remove them from the water for disposal.
Paint spray booths for vehicles are typically 100 – 300 feet in length and usually contain many robotic and manual spray zones. The temperature and humidity are rigorously controlled in these systems. As items are painted in these booths, a certain amount of paint does not contact the article being painted and forms a fine mist of paint in the air space surrounding the article. This paint must be removed from the air. To accomplish this, the contaminated air is pulled through the paint spray booth by exhaust fans. A curtain of circulating water is maintained across the path of the air in such a way that the air must pass through the water curtain to reach the exhaust fans. As the air passes through the water curtain, the paint mist is “scrubbed” from the air and carried to a sump basin (sludge pit), usually located below the paint spray booth. In this area, the paint particles are separated from the water so that the water may be recycled and the paint particles disposed of as paint sludge. The paint detackifiers commonly added to these systems are either melamine-formaldehyde based, based upon acrylic acid chemistry, or chitosan.〔Albu, Mike; Bui,Nang (The Use of Chitosan in Paint Detackification ) accessed 04/12〕
The word detackification in the context of spray painting has come to mean more than mere charge-neutralization. In fact, it now means the entire process, which includes both detackification and flocculation.〔(A Green Detackifier for Paint Sludge ) accessed 04/2012〕
