Coil cement is a critical factor in coreless induction furnace safety and performance. Coil cement must facilitate optimal heat transfer whilst offering enough resistance against molten metal to avoid coil puncture.
The NORCOIL™ product range offers easy installation in terms of handling, setting time and drying, as well as optimal performance during operation. NORCOIL™ provides the most advanced resistance against vibration or frequency impacts.

NORCOIL™ A 337 is typically used as a reference product in a number of international markets. It is also popular with customers and recommended by many furnace OEM providers. NORCOIL™ A 337 offers excellent thermal stability and mechanical strength while ensuring minimal cracking and gas infiltration.
Coil cement should be mixed with water and applied using a patching tool (or casted if it is a self-flowing version). This process requires a tight frame. Mix preparation and application in between the coil tubes must be carefully managed to avoid any heterogeneity inside the coating.
