Interview with George Haig on Silbond products from technical perspective – For purposes of making refractory and ceramic shapes Silbond 40 ( 40% SiO2 ) was recommended. Summary of method is as follows:
- mix SilBond with the organic amine
- mix SilBond / Amine with refractory ( sand & ? … ) ( usually use more than just sand: Zircon flowers, alumina etc ) ( quoted: used for casting jet engine housings and glass handling tools )
- add water to facilitate
- pack or vibrate the wet casting – given water and amine you have a given amount of time to get the job done
- Silbond 40 – Cost = 2.22 / lbs- minimum quanties for 1 drum. Minimum 150$ min order. ( Lisa Rally – costing information )
