| Silbond H-5 |
 |
| SILBOND H-5 is a prehydrolyzed binder with a high percentage of available silica, about 20% as SiO2. Its primary use is in the production of facings and molds for precision casting of beryllium-copper, aluminum, steel, and other metals using permanent patterns. Other applications include ceramic shapes, cores and coatings. Bulletins describing specific applications, with formulations, are available from Silbond Corporation. |
