Phenolic resin-bonded core sands

For very complex core geometries or for areas that can no longer be sanded later. Best temperature resistance and strength under sand pressure. When design freedom and strength reach their limits with furan, phenol is the right choice. Excellent for steel and iron castings.

Synthetic sand (medium grain size 0.16 mm)

Layer height: 0.26 mm
Strength: 500 ± 100 N/cm²
Tolerance: ± 0.5mm
