Master Bond EP21SC-1 Two Component Epoxy Resin System
Categories: Polymer; Thermoset; Epoxy; Epoxy Encapsulant, Unreinforced

Material Notes: Product Description: Master Bond Polymer System EP21SC-1 is a two component epoxy system featuring 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. Not only does EP21SC-1 offer good 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. EP21SC-1 cures rigid with a Shore D over 95. It has good 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, where excellent abrasion resistance is needed.

Product Advantages:

  • Convenient mixing: non-critical one to one weight or volume mix ratio.
  • Easy application: smooth paste consistency.
  • Versatile cure schedules: convenient room temperature cures or faster elevated temperature cures.
  • Good abrasion resistance, tough, high strength coatings, liners and adhesive/sealants.
  • High bond strength to a wide variety substrates.
  • Low thermal expansion coefficient.
