Master Bond EP38CL Adhesive Features Toughness and Durability
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Description: Master Bond EP38CL is a lower viscosity, optically clear two component epoxy system for high performance bonding, coating, sealing and small encapsulations, featuring toughness and durability. The mix ratio is 100:60 by weight. This system has easy handling with a working life of 40-50 minutes. Its physical appearance optically clear and glossy. EP38CL has a relatively higher Shore D hardness its special blend confers upon it a “toughness”. Specifically, it possesses good impact resistance, thermal cycling capabilities as well as the ability to withstand mechanical shock better than typical epoxies that are higher on the Shore D scale. Also, EP38CL bonds well to a wide variety of substrates, such as metals, ceramics, glass, composites, many rubbers and plastics. Its electrical insulation properties are solid. The service temperature range is -60°F to +250°F. EP38CL is used in optical, aerospace, opto-electronic and specialty OEM applications, particularly when a rigid system with good toughness is desirable.

Product Advantages:

  • Easy to apply by roller or brush. Convenient working life
  • Excellent toughness, capable of withstanding aggressive thermal cycling
  • Appealing electrical insulation properties
  • Imposing optical clarity
  • Reliable adhesion to a variety of substrates
  • Good physical strength properties as well as low shrinkage upon curing
