Abstract
A method for making a lubricating fast-setting epoxy compound comprising: mixing under vacuum dispersion a first micro-crystalline filler, a first talc, and a titanium oxide into a hardenable epoxide containing liquid forming an epoxy base. A second micro-crystalline filler, a second talc, and a hydrocarbon resin are mixed forming an accelerator mixture. A methylamino accelerator is mixed into the accelerator mixture forming an epoxy accelerator. Substantially equal amounts of the epoxy base and the epoxy accelerator are mixed to form the lubricating fast-setting epoxy compound having a high lubricity and a curing time ranging from two minutes to twelve minutes. Adjusting the mixing speed and temperature of the epoxy base, the accelerator mixture, and the epoxy accelerator is contemplated to promote homogeneity. The epoxy base can also include a flatting agent. The epoxy accelerator can also include a modified aliphatic amine, an acrylic resin, a coloring agent, or combinations thereof.
