  The composition of the matrix holding the large abrasive resistant particles in position may vary over a wide range. For example, many types of polymers may be used, such as: epoxide polymers; unsaturated polyester (carboxylate-glycol adduct); cone crusher south Africa a polyurethane; a polyimide or polyamide resin or the like. A particular polymer found to function particularly well as the matrix is an epoxy resin containing a thixotropic agent which resin is cured by means of a mixed polyamine/polyamide curing agent. The thixotropic agent used is a pure "CALIDRIA" asbestos sold under the designation RG-144 by Union Carbide Corporation. Other agents might be Bentonite, fumed silica, M-P-A by Baker Caster Oil, polyacrylamide and so forth.
  
  In the composition of this invention, it has been found desirable to provide the large abrasive resistant particles and the co-abrasive filler in both the resin and curing components of the epoxy resin composition. The purpose of doing this is two-fold. First,aggregate plant, it provides a mixing ratio between the resin and curing components of approximately 2 to 1 whether the components are measured by weight or volume. Second, it provides thorough wetting of all the abrasive particles and co-abrasive filler. A thorough wetting of these materials is difficult to obtain if the materials are provided in only one of the two components. A specific example of a suitable composition for use in this invention is:
  
  In this example the resin may be supplied in one can and the curing agent in another, the two being sold together with the resin can being, for example, a 1-gallon container and the curing components being in a one-half-gallon can. This is merely an example and it should be understood that any suitable sizes could be used depending upon the needs of the customer and the amount of material to be used in an application. But a 1-gallon can for the resin and the one-half-gallon can for the curing agent has been found convenient. In such a situation a proportion of the amounts would be emptied from each and thoroughly mixed before application to the surface to be protected. And, if all of the resin and curing agents in the two-can kit are not used at once, the cans may be sealed up and used later. The above example, when mixed, applied, and cured, has the following characteristics: Tensile Strength 4,000 psi Compressive Strength 15,000 psi Heat Deflection Temperature 195°F. Lap Shear Strength 2,000 psi Gel Time 90 min. Working Time 30 min. at 70°F.
