Paint spray booths are enclosures in which industrial production painting operations are performed. Paint spray booths both protect the paint spraying operation and permit control of emissions from paint spraying operations.
In commercial paint spraying processes, frequently as much as fifty percent of the paint used is not deposited on the object to be painted. Much of the overspray is removed in water wash systems used to scrub the overspray particles from exhaust air.
However, some of the overspray is unavoidably deposited on robots, paint spraying equipment, transfer line carriers, paint booth walls and windows. If such objects and surfaces are not protected from the overspray, they can quickly become covered with paint. Paint deposits on robots and paint spray equipment can lead to equipment malfunctions or flaking off of paint on articles being painted which can adversely affect the quality of the painted article. Also, overspray build-up on walls and windows can diminish light levels in the paint spray booth and render windows useless.
The walls of paint spray booths may be protected by pigmented barrier coatings which are preferably white to make the paint booth brighter. Such pigmented coatings are not appropriate for use on equipment, robots or windows in paint spray booths since such coatings would obscure signs and windows.
Clear coatings are known for application to equipment, robots or windows in paint spray booths but have not been totally satisfactory in all respects. We offer clear barrier coatings.
Since the barrier coatings must be periodically removed and replaced with a fresh coating, it is vital that the coating be easily removable. Known clear coatings are normally removed in one of two ways, either by water washing or peeling off as a film.
With barrier coatings on equipment and robots, it is preferred to provide a peelable coating which may be removed without application of water that could harm the robots or equipment. On broad, flat surfaces that can be washed off with water or subjected to a high pressure water spray, it is generally preferred to wash the barrier coating off. The barrier coating if washed off must not interfere with the water wash system of the paint spray booth and must be compatible with the filtration or residue removal system used in the paint spray booth. Since known clear barrier coatings are limited to one preferred removal technique, it is generally necessary for optimal performance to use two different types of clear coating in a paint spray booth.
Booth Grease-9000 baffle coating is a thick, brown petroleum base coating that imparts a smooth wax-like film to various substrates. It is designed for use in areas where paint buildups occur and require mechanical removal.
BOOTH GREASE 4550 Gold has been formulated for application to baffles, back sections, stacks, underbooth areas and other locations where a greasy coating is desired to prevent adhesion of paint overspray.
BOOTH GREASE 4568 White has been formulated for application to baffles, back sections, stacks, underbooth areas and other locations where a greasy coating is desired to prevent adhesion of paint overspray.
