| DESCRIPTION |
GAYREX the standard silicate cement was developed to solve corrosion problem involving oxidizing acids. It is the only cement that will resist high temperatures and highly concentrated solutions. It is specially recommended for the construction of Chimneys, Incinerators, Roasters and other high temperature equipments. Due to its high porosity and relatively low strength. GAYREX is not recommended for use in water, alkalis, dilute acids solutions and extreme tribunal conditions.
