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.
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.
EP21SC-1 can 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.
System includes 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.
