Resital HB®-Typen
Urea-modified phenolic resins
Cores made using resins of this group are employed in gray and ductile iron casting. The main field of application is in engine block castings (block and heads). The advantages of this type of resin are the relatively brief curing time at a corebox temperature of 220 °C, high thermal resistance of the cores, and dimensional accuracy of the castings.
