Refractory Mortar

INSULFIRE high temperature refractory mortar is a kind of new type of inorganic cementitious material made from powder of the same material by adding inorganic binder and agent after reaction. There are three grades of INSULFIRE high temperature refractory mortar say RM 1400, RM 1600 and RM 1750 available of different grades of masonry products.

Characteristics

High bonding strength, good overall masonry structure
Good air tightness, corrosion resistance and long service life
High load softening temperature and low shrinkage at high temperature
Good workability, high bond strength and small shrinkage after burning
Good slag resistance, small masonry mortar joint
