Product use:

Product use:

This product is suitable for alloy steel, high manganese steel, stainless steel, heat-resistant steel, etc. This is because the carbon content of the above products is extremely strict, and the lower the carbon content of the materials used, the better, so as to avoid the serious carbon increase of the above steel. Therefore, the heat insulation coating agent for alloy steel riser developed by our factory is the only choice for you and the most ideal heat insulation coating agent for alloy steel and other steel

3、 Product features:

It is suitable for the products with heat insulation covering of exposed riser and common riser of sand mold of castings, such as alloy steel, high manganese steel, stainless steel, heat-resistant steel, etc. The biggest feature of the product is long heating time, heating time up to 30min. Covering the riser, the product immediately burns and heats, prolonging the setting time of riser by 4-5 times, heating time for about 30min, and does not affect the quality of original metal.
