ABSTRACT:
Sprayable, pre-mixed, mine sealant compositions having enhanced strength properties and capable of retarding flame propagation and suppressing combustibility of substrate materials are disclosed in three general forms. In the first form, an alkaline silicate material such as sodium silicate is employed with perlite and a mineral acid in order to provide the above properties. In a second formulation, the first form is augmented by white pigments. In a third formulation, additional bulking materials e.g., cellulose are added to provide enhanced structural integrity and mine sealant qualities.
