We offer a variety of sand additives that improve the performance of moulding and core sands. These additives enhance properties such as strength, thermal stability, and flowability, ensuring the best possible results in casting processes.

During casting, quarts san d undergoes expansion at around 573 degrees celcius, which can cause veining or cracking in the core. Veinseal counteacts this effect by absorbing the thermal expansion stress, allowing sand cores to retain their original shape and integrity throughout the metal pouring process. 

The recommended addition rate of VeinSeal typically ranges between 10% and 40%, depending on the base sand type, core geometry and specific casting requirements.
