Product Details

Refractory clay mortar uses hard clay clinker as the base material, combined with soft clay or chemical bonding agent.

Features: Refractory clay mortar has the characteristics of high refractory performance and strong resistance to glass erosion. Good use performance, strong bonding performance, good water retention and smearing, modulated into mud without precipitation. It produces ceramic bonding at high temperature, which further improves various properties. High filling density, low water consumption, so the masonry is densely organized.

Method of use: Add water and mix evenly when using, the amount of water added should be increased or decreased according to the consistency. Masonry should be full and even when hanging mud.
