Foster® Cryogenic Adhesive 82-77

1 of 184 products in this brand
Foster® Cryogenic Adhesive 82-77 is a chemically curing adhesive with the capability to achieve high tensile strength and adhesion at room temperature. It effectively bonds to a range of surfaces, including metal, wood, and masonry. This adhesive is supplied in a virtually 100% solids form, facilitating immediate bonding for non-porous surfaces without the risk of solvent entrapment issues.

Product Highlights
  • Cryogenic adhesive also can be used as a fabricating adhesive.
  • It often provides bonds stronger than the materials being joined.
  • The cured film has excellent resistance to solvents, water, and many chemicals.
  • The adhesive also performs well with various materials after thermal shock exposure at cryogenic temperatures.
  • It is an ideal choice for bonding steel pipe shoes or saddles to pipe insulation assemblies.
  • Cryogenic adhesive meets requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives, and Sealants.

Preparation and Application Information

Material Preparation

  • Mixing Instructions: Mix Part A and B in a clean container with a cage type mixing paddle and a 1/2 inch (12.7 mm) heavy duty electric drill on slow speed (350 rpm).
  • Mix thoroughly for 3 minutes, making sure to scrape the sides and the bottom of the container. While mixing, slowly add Part C (aggregate) and mix an additional 2 to 3 minutes until uniform.
  • Do not lengthen or shorten the mixing time.
  • Do Not Thin.
  • Mixing Ratios: Foster® Cryogenic Adhesive is supplied in 40 lb. kits.
  • Either mix the entire kit or divide each component into 2 equal parts and mix half of the kit at one time.
  • Do not attempt to mix less than half of a kit.

Application

  • Apply by trowel to clean, dry surfaces only.
  • Metal surfaces should be solvent cleaned beforehand and allowed to dry.
  • When used in cryogenic applications (below -40°F/-4°C), for maximum adhesion the metal surface must be clean and free of any surface contaminants and sandblasted, sanded/roughened or primed with a polyamide epoxy primer.

Application Temperature 

  • Apply between 60°F and 100°F ambient temperature.
  • At temperatures above 95°F, the pot life will be less than 30 minutes.
  • To prolong pot life at high temperatures, Foster® Crogenic Adhesive should be spread out as much as possible immediately after mixing.

Coverage Range 

  • When used as a bedding compound or between surfaces of masonry or urethane foam, suggested thickness: 1/16 to 1/4 inch (1.6 to 6.4 mm).
  • When used in cryogenic applications or where bonding to metal, suggested thickness: 1/16 to 1/8 inch (1.6 to 3.2 mm).

Clean Up 

  • Before adhesive cures, clean tools and equipment with chlorinated solvent (non-flammable) or mineral spirits (flammable). Cured 82- 77 is extremely difficult to remove.

¹ - Supplied as a 3-part 40 lb. kit. 15.5 lbs./gal. yields 2.6 gallons

² - At very low cryogenic temperatures (past -100°C), cellular glass to other metals, such as aluminum, may result in shear failure of the insulation due to differences in contraction  rates of the metal and insulation.

Storage & Handling

Shelf Life
12 months
Handling Conditions
  • Store between 40°F (4°C) and 100°F (38°C).
  • Apply between 60°F (16°C) and 100°F (38°C).
  • Pot life is longer at lower temperatures and shorter at higher temperatures.
  • Mixing large quantities also shortens pot life, thus mixing more than one kit at a time is not recommended.
