Nitinol ElectroPolish™
Nitinol ElectroPolish™ is the standard 70% methanol/30% sulfuric acid blend used at lower temperatures to polish Nitinol and other titanium alloys to a smooth surface and bright surface. Nitinol ElectroPolish provides optimum corrosion protection for implantable medical devices. The product’s key additives are pre-mixed and ready to use. This eliminates operator error and provides the user with consistent process performance.

ChemPolish Ti6Al4V™
ChemPolish Ti6Al4V is formulated to deoxidize and chemically polish titanium grade 5 and other high Ti alloys. Depending on an incoming surface condition the degree of polishing obtained with this product may be sufficient or a good step before electropolishing.
ChemPolish Ti6Al4V will remove base metal very slowly. If a more aggressive chemistry is desired, treat initially with MicroPolish II (RDZ2059 (available from RBP), then treat with ChemPolish Ti6Al4V.

MicroPolish™ II
MicroPolish II and MicroPolish are two inhibited deoxidizers formulated for titanium and titanium alloys including Nitinol. Each product acts as a cleaner/deoxidizer and slow chemical polish effective in removing surface metal oxides but only slowly etching base metals. Of the two polishes, MicroPolish II is slightly less aggressive. Overall, the etch rates are low for both polishes when compared to traditional deoxidizing chemistries. They are particularly suitable for applications where avoiding dimensional and weight losses is of critical importance (for example in devices utilizing fine wires).

Alkaline Descale™
Alkaline Descale is designed to descale CoCr (cobalt chrome) and other chromium based alloys before electropolishing. It will convert insoluble oxides to soluble forms and thus assure uniform subsequent processing.
Alkaline Descale is provided in two parts, A and B.
