HT-Zinc (Grey) (DURO 57) offers excellent temperature resistance with zinc base casting alloys. This compound features very high tear strength and elongation physicals making it an excellent choice to use with castings that have a certain amount of undercuts. Additionally, the mold is very flexible which aids in the removal of casting from mold cavities. Similar to Organic Rubber, it offers excellent mold life, particularly when casting Pewter, Tin and Lead-Base alloys.
