Pro-HT is a high technology phosphate bonded product designed for casting high temperature alloys such as Platinum and Steel with metal pouring temperatures up to 2100°C / 3800°F. Pro-HT has a high refractory content and fine particle size distribution, this produces high fired mould strength with precise detail replication of the wax pattern under the harsh casting conditions these alloys demand.
Pro-HT is packaged in aluminium foil bags to achieve a long lasting, consistent and high quality powder. Phosphate bonded powders are extremely moisture sensitive and exposure to atmosphere will degrade product performance. Please re-seal bag after use to ensure consistent results from start to finish of the bag.
Pro-HT is water based investment powder moulded using the traditional flask and rubber base system. Pro-HT can be mixed either by hand or using a vacuum mixer following the mixing instructions above right. After pouring, Pro-HT is to be bench set for a minimum of 2 hours before removing the rubber flask base and firing in a furnace using the Pro-HT burnout cycle.
