RESPIRABLE SILICA
HAZARD FREE
INVESTMENT POWDER’
The investing procedure remains the same for vacuum mixing and conventional hand mixing using the same standard equipment currently used in any jewellery manufacturing operations.
The Water / Powder ratio recommended for best results is between 36 – 38 parts water to 100 parts powder (36-38:100) for machine mixing or between 38 – 40 parts water to 100 parts powder (38-40:100) for hand mixing.
Burnout cycle remains the same as regular investment powder, meaning casters do not have to modify any burnout procedure. Can be used in all current burnout furnaces.
