DFense Blok is a new, innovative wearing compound that, when used with DFense Blok Surface Wetting Agent, drastically increases drop impact strength over 1-in. ceramic tile (as tested using 85-lb. weight with 0.25-sq.-in. striking surface). The wetting agent is a 2-part thixotropic epoxy gel system that improves the ease of application and cured adhesion properties of the wearing compound. DFense Blok is ideal for use in repairing, rebuilding and protecting typical wear and abrasion applications, such as cyclones, and screw conveyors and augers. Available in 30-lb. pails, DFense Blok is mixed in a 2:1 ratio and has a working time of 25 minutes at room temperature. A non-sagging compound, it can be easily applied by trowel at thicknesses of 3/4 in. on vertical surfaces and 1/2 in. on overhead surfaces. The compound achieves functional cure in only 4-5 hours, allowing equipment to be returned to service quickly. According to the manufacturer, using DFense Blok Surface Wetting Agent significantly improves the adhesion of DFense Blok compared to traditional epoxy products (per ASTM D 1002).
