ABSTRACT:
A composition of matter especially for the formation and development of wear surfaces of decorative or aesthetic character is provided which comprehends a matrix and discrete reforcing elements embedded in the matrix. The matrix is resin-based with the resin being hydrogenated bis-phenol A which is mixed with a suitable low profile additive, a catalystic agent, a flame retardant, an extender, and a inhibitor while the reinforcer is constituted of glass fiber particles. The method for preparing such composition comprises the intermixture of the matrix ingredients into a blend having a viscosity with the range of approximately 60,000 to approximately 100,000 centipois; to such blended mixture there is then added a viscosity increasing agent but with the glass fibers being introduced prior to the interreaction of the viscosity increasing agent; agitation being provided to bring about appropriate intermixture of the glass fibers and with such mixture being stored for a sufficient period at a predetermined temperature to permit the viscosity increasing agent to bring about a high level of viscosity. The then partial cure is now in condition for final cure through the particular compression mold process for creation of the intended article to be produced.
