  • Water-based flushing solution with low VOC content
    Patent number: 5972865
    Abstract: A purge concentrate for purging paint spraying and other coating equipment has about 20%-60% by weight water; about 10%-40% by weight of an active solvent; about 10%-50% by weight of a co-solvent; about 1-9% by weight of a penetrant; and about 0.2-2.0% by weight wetting agent. It need not be heated to the curing temperature of heat curing paints and thus purges these paints more effectively.
