Hot Topping Compounds
Hot Toppings features a unique combination of insulating and exothermic characteristics for improved feeding of castings. They are available for both ferrous and non-ferrous applications. Foundries are able to reduce production costs due to the topping compounds ability to:
- Reduces riser heat loss to atmosphere
- Maintain open riser to assure continued feeding
- Reduce piping in risers
- Assure integrity of the casting
- Increase metal yield
- Easy to apply
