Cu/SCRUB 4F-9.1 is an acidified pumice scrub designed to promote cleaning and micro-roughening of copper laminate. Cu/SCRUB 4F-9.1 is formulated with 4F Grade, friable pumice, and contains antioxidant components to inhibit cupric onside formation after the cleaning cycle. During use, fractured particles from friable pumice continue to present sharp cutting edges rather than rounding off, thereby assuring a long and consistent operating life. Cu/SCRUB 4F-9.1 also exhibits a low concentration of free silica, and is therefore safer to work with than traditional pumice.
- Cu/SCRUB 4F-9.1 is mildly acidified, thereby chemically stripping light oxides from the copper surface while producing a uniform micro-roughened copper surface.
- Cu/SCRUB 4F-9.1 contains anti-oxidants to protect the cleaned copper.
- Cu/SCRUB 4F-9.1 is formulated with friable 4F Grade pumice, assuring a continued source of sharp edges as the material fractures during use.
- Cu/SCRUB 4F-9.1 contains a low concentration of free silica, promoting a safe working environment.
