ABSTRACT:
The abatement of bio-hazardous particulate materials, such as asbestos, has a high priority for providing children with a future. The method of the present invention involves abating such materials by encapsulating them in a simple and effective manner. The method uses a special formulation that when applied to a potentially bio-hazardous surface, such a coating on a substrate, seeps into the pores of the surface, encircles and encapsulates the particles. The formulation also bonds the encapsulated particles to the surface of the substrate carrying the coating. The results of the method are complete encapsulation of potentially bio-hazardous particulate matter found in a coating on a substrate, bonding of the encapsulated particles to the surface of the substrate, and finally, the sealed coating is resistant to impact and abrasion.
