PRO-HT
SACK : 22.7 Kg
Box : 10 kg.
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.
Product Detail
PRO-HT
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.
