Description
Mortel MPH is a specialised dry refractory mix for laying and repairing products based on periclase-chromite and magnesia materials. It provides strong joint adhesion, resistance to extreme temperatures and aggressive metallurgical slags. It is used in units operating under high thermal and chemical loads. The mixture is easily mixed with water, forms a plastic solution and, after drying, forms a dense, heat-resistant joint without cracks.
