These Modeler's™ Sticky-Wax pellets have superior bonding strength for adhering to dissimilar waxes and are formulated to melt and set quickly. This wax is ideal for filling fine lines and minor defects in wax models and for efficient treeing of wax models. Ideal for short-run or production use. In treeing, Sticky-Wax creates a smooth transition from main sprue to pattern sprue. The optimal temperature for best adhesion of your wax patterns is 199°–224°F (93°–107°C).
