ADHESIVE FOR FIREPROOFING AND FIBER ENCAPSULATION ABSTRACT OF THE DISCLOSURE A fireproof adhesive material is provided which accomplishes fiber encapsulation and permits the development of spray on type fireproof insulation. The fireproof adhesive material incorporates a predetermined quantity of sodium silicate in liquid form with which is mixed a quantity of surfactant/water solution sufficient to render the cured fireproof adhesive flexible and to provide for emulsification in the liquid state thereof. The adhesive also includes a sufficient quantity of silicone water repellent to render the cured adhesive durable, chemical resistant and water repellent. Further, the adhesive material may include a liquid stabilizer, plasticizer compound to enhance the flexibility of the cured adhesive. For odor control, a quantity of a malodor control agent may also be incorporated. The fireproof adhesive material is prepared in the form of a liquid mixture wherein the ingredients of the mixture are basically incompatible and wherein the ingredients are introduced during continuous agitation in a particular order and after being placed in assembly, the incompatible liquid constituents are forced together by agitation for a sufficient period of time to render the mixture substantially inseparable. Upon curing, the adhesive mixture forms a solid, pliable or flexible mass having good surface adhesion. When in the liquid form the mixture has a quality of efficient penetration and fiber encapsulation to render hazardous fibers nonviable and fireproof.
