Kohesi Bond KB 1039 CRLP Two component, optically clear epoxy system for cryogenic applications
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive; Epoxy Encapsulant, Unreinforced

Material Notes: Product Highlights:
  • Superior optical clarity
  • Very good flow properties
  • Withstands cryogenic shocks and cycling
  • Outstanding mechanical strength properties
  • Excellent electrical insulation properties
  • Capable of passing NASA low outgassing
Kohesi Bond KB 1039 CRLP is a two component, heat curing epoxy system suitable for bonding, sealing, coating, potting and encapsulation. It has a favorable 100:65 (Part A: Part B) mix ratio by weight. This epoxy system offers excellent adhesion to a variety of substrates, such as metals, composites, glass, ceramics, most plastics and rubbers. It offers a long working life at room temperature of over 4 - 5 hours and cures quickly at elevated temperatures. The optimal cure schedule is a room temperature set-up followed by a heat cure at 90°C for 3 - 5 hours. KB 1039 CRLP is specially formulated for use in cryogenic applications. It is resistant to cryogenic shocks and cycles down to 4K. It is optically clear and it is capable of passing NASA standards for low outgassing (ASTM E-595). This adhesive fosters outstanding physical strength properties. It offers very low shrinkage upon cure and excellent flow properties. In addition to superior electrical insulation, it also offers very good chemical resistance. This product offers first-rate optical clarity and cures rigid. KB 1039 CRLP is widely used in optical, optoelectronic, electronics and aerospace industries, where optical clarity, low outgassing and cryogenic serviceability are key requirements.
