Customer Requirements

A common problem in porcelain coating is the removal of porcelain overspray from part hangers and the subsequent processing of the removed porcelain powder.  Porcelain powder is very hydrophobic and forms a solid cake in aqueous environments.  This customer desired a cleaning solution that would efficiently wet the porcelain and allow it to maintain good flow properties for ease of removal from the cleaning bath.


MetaLube formulated a specialized cleaner to enhance removal of the porcelain from the hangers, and to allow easy separation of the settled powder from the bath.  MetalKleen 4920 P efficiently wets the porcelain overspray and prevents settled powder from forming a solid cake.  The customer is now able to pump the loaded process bath to a separator and drain the porcelain powder from the cone bottom.  The bath can then be pumped back to the tank for re-use.  This customer has greatly reduced the maintenance costs associated with weekly cleaning of their wash tank, and processing of the spent powder.
