  • Excellent hardness
  • Convenient handling
  • Cures at ambient temperatures
  • Silicon carbide filled
  • Paste consistency

Product Description

Master Bond EP21SC-1 is a two component epoxy system featuring truly exceptional abrasion resistance. This high performance compound utilizes silicon carbide as a filler material and can be used as a coating, adhesive or sealant. It has a convenient, non-critical one to one mix ratio by weight or volume. It is 100% reactive and does not contain any solvents or diluents. Also, the system has minimal shrinkage upon cure. EP21SC-1 cures at room temperature and can be accelerated with heat. The optimum cure schedule is overnight at room temperature followed by 2-3 hours at 150-200°F. First and foremost EP21SC-1 has superior abrasion resistance. It can also withstand exposure to chemicals including water, oils, hydraulic fluids, acids and bases over the wide temperature range of -60°F to 250°F. It has very good adhesion to treated metals, ceramics and many plastics. Some other desirable attributes include a Shore D hardness greater than 90, exceptional dimensional stability and very high compressive strength. It has superior electrical insulation properties and its thermal expansion coefficient is desirably low. The color of Parts A and B is dark gray. EP21SC-1 is widely used in chemical and mechanical processing, maintenance and tank and chute applications, especially when excellent abrasion resistance is advantageous.
