Vitallium 2000 Investment - Elephant Dental

Mix investment and liquid thoroughlyand pour the mixture,carefully filling the ring.Transfer the case to a vibratingtable and allow the mold tovibrate until set (approximately15-20 minutes). After theVitallium 2000 Investment hasset, remove it from the vibratingtable and allow it to set anadditional 30 minutes.5. Grind down the excessVitallium 2000 Investment fromthe top of the case (rings) usinga model trimmer. Leave at least1 /2 inch of Vitallium 2000Investment above the highestpoint of the refractory model,and allow it to set an additionalone hour before burnout.Burnout and Casting1. Place the rings in a cool furnaceand heat to 1200˚F (649˚C)and hold for 30 minutes.2. Increase the furnace temperatureto 2000˚F (1093˚C) andsoak for one hour.3. Remove rings from furnace andcast using V-2000 or V-2000Plus alloy. Follow casting instructionsprovided for the alloy.4. Allow cases to bench cool priorto divesting.

Do not breathedust. May cause delayed lung injury (silicosis,pneumoconiosis). The I.A.R.C. (International Agency forResearch on Cancer) reports (I.A.R.C. Monograph 68) thereis sufficient evidence in humans for the carcinogenicity ofinhaled crystalline silica in the forms of quartz or cristobalitefrom occupational sources. The NTP (National ToxicologyProgram) reports (Ninth annual report on Carcinogens) thatRCS is known to be a carcinogen based on sufficientevidence from studies in humans indicating a causalrelationship between exposure to RCS and increased lungcancer rates in workers exposed to crystalline silica dust.Follow OSHA Safety and Heath Standards for crystallinesilica.
