Kohesi Bond KB 1372 SC Two component, thermally conductive and chemically resistant epoxy
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive; Epoxy Encapsulant, Unreinforced

Material Notes: Product Highlights:
  • Exceptionally high Tg
  • Very good flow properties
  • Superior chemical resistance
  • Long working life at room temperature
  • Exceptional electrical insulation properties
  • Phenomenal abrasion resistance
Kohesi Bond KB 1372 SC is a two component, heat curing epoxy system suitable for bonding, sealing, coating, potting and encapsulation. It has a convenient 10:1 (Part A: Part B) mix ratio by weight. This epoxy system offers a high glass transition temperature (Tg) of > 172°C. It rapidly cures at moderately elevated temperatures and can achieve even faster cures at higher temperatures. It takes 4 - 6 hours to cure at 70°C, 20 - 40 minutes at 100°C and 10 minutes at 125°C. Kb 1372 SC is an silicon carbide filled system, offering first-rate abrasion resistance. It offers very long working life at room temperature, allowing to bond and pot large parts. It has an extensive service temperature range of -50°C to +230°C. This adhesive fosters outstanding mechanical strength properties, along with dimensional stability. KB 1372 SC adheres well to a wide variety of substrates including metals, ceramics, most plastics and glass. In addition to superior electrical insulation, it also offers excellent chemical resistance to a variety of acids, bases, solvents and other chemicals. Part A and Part B are dark gray in color. KB 1372 SC is widely used in applications requiring excellent chemical resistance at elevated temperatures, long open time and very high abrasion resistance.

Typical Applications:

  • Bonding
  • Sealing
  • Coating
  • Potting
  • Encapsulation
