PUMICE/Scrub 4-F is a pumice scrub designed to promote micro-roughening of copper laminate. PUMICE/Scrub 4-F 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. PUMICE/Scrub 4-F also exhibits a low concentration of free silica, and is therefore safer to work with than traditional pumice.
- PUMICE/Scrub 4-F produces a uniform micro-roughened copper surface.
- PUMICE/Scrub 4-F contains anti-oxidants to protect the cleaned copper.
- PUMICE/Scrub 4-F is formulated with friable 4F Grade pumice, assuring a continued source of sharp edges as the material fractures during use.
- PUMICE/Scrub 4-F contains a low concentration of free silica, promoting a safe working environment.
