HIGH TEMPERTATURE CASTING
Pro-HT Platinum
High Temperature Investment Powder
The extreme melting point of Platinum of up to 2000°C requires a specially formulated investment powder to cope with the intense casting conditions. Pro-HT Platinum is a water-based Phosphate-bonded investment powder, which has been successfully used for the casting of Platinum alloy for many years.
Traditional Platinum casting investments use a 2-part acid-bonded chemical reaction to attain mould strength at an elevated temperature, whereas Pro-HT Platinum utilises a water-based, phosphate-bonded chemical system and sets in an exothermic reaction at room temperature.
