- 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.

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.

- Note
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.
