摘要: A process for chemical cleaning and corrosion inhibition of pipework, typically in closed loop systems, that avoids or significantly minimises the requirement for wastewater discharge where the system is first acidified using a mixture of cleaning agents capable of dissolving metal oxides. The method then precipitates any dissolved contaminants and separates the precipitate from the carrying fluid. Further elements of a combined corrosion inhibitor package are then added to any cleaning agent ions that remain in solution to develop a fully functional corrosion inhibition package to protect the metals of the system.

摘要: The present invention is a charge complexing chemical composition that protects metal during polymer removal. The polymer coatings include crosslinked systems by chemical-amplification and photoacid generated (PAG) means as in epoxies. The system includes a solvent, a charge complexing additive, and an acid that creates a protective complex for sensitive metals during the dissolving and rinsing practice needed for processing microelectronic parts. The composition can be utilized with a method for removing partial and fully cured crosslinked coatings that originate from chemical amplification or PAG-epoxy photoimageable coatings.
