Resistance, stable

Rhodium. Rhodium is the most commonly plated platinum-group metal. In addition to its decorative uses, rhodium has useful properties for engineering appHcations. It has good corrosion resistance, stable electtical contact resistance, wear resistance, heat resistance, and good reflectivity. The use of rhodium for engineering purposes is covered by an ASTM specification (128). Typical formulas are shown in Table 15. The metal content is obtained from prepared solutions available from proptietary plating supply companies. Replenishment is requited because anodes are not soluble. Rhodium for decorative use may be 0.05—0.13 p.m thick for industtial use, it maybe 0.50—5.0 p.m thick.

Polytetrafluoreethylene Costly, but highly corrosion-resistant. Stable up to 250°C. 

Sodium glycine carbonate is a non-hygroscopic, heat-resistant, stable substance. However, the carbon dioxide yield—approximately 18% by weight—is only about one-third of NaHCOs. 

Properties High hardness, abrasion, and chemical resistance except to hydrogen fluoride and hot strong caustic low expansion coefficient. Corrosion resistant, stable to heat-shock, easy to clean and decontaminate. 

Another advantage of this stable bromine epoxide is that it can be incorporated into a wide variety of epoxy resins. Figure 7 shows a BPC curve where an experimental moisture resistant stable bromine epoxy novolac outperformed stable bromine CEN by a substantial margin.
