Loctite LB 8040 Freeze & Release Penetrating Oil 310g
Available
Loctite LB 8040, known as Freeze & Release, is a mineral oil penetrating oil for freeing rusted, corroded and seized parts. The lubricant stream is chilled to a maximum of -43 °C, which shock-freezes the part and causes microscopic cracks in the rust layer.
The thin oil then wicks into the rust by capillary action. Once the part is free it stays lubricated and protected from corrosion. This is a 310 g aerosol, applied by spray to metal parts.

Spray from about 10 to 15 cm for 5 to 10 seconds. Allow 1 to 2 minutes before trying to release the part, and repeat if necessary.
Storage and handling
Store unopened in a dry location, with optimal storage at 8 °C to 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product. It is a pressurised container: protect it from sunlight and do not expose it to temperatures above 50 °C.
Limits and safety
Not recommended for pure oxygen or oxygen-rich systems, or as a lubricant for chlorine or other strong oxidising materials.
Frequently asked questions
How cold does Loctite LB 8040 get?
The lubricant stream reaches a maximum chill-down of -43 °C. This shock-freezes the part and causes microscopic cracks in the rust layer.
How long should I leave Freeze & Release before trying the bolt?
Spray from about 10 to 15 cm for 5 to 10 seconds, then allow 1 to 2 minutes. Repeat if necessary.
What is Loctite LB 8040 made of?
A special mineral oil formulation. The oil wicks into the rust by capillary action and leaves released parts lubricated and protected from corrosion.
Can I use Loctite LB 8040 in an oxygen system?
No. It is not recommended for pure oxygen or oxygen-rich systems, or as a lubricant for chlorine and other strong oxidising materials.
How thin is the oil?
Lubricant viscosity is less than 5 mPa·s, and density is 0.6 g/ml at 20 °C.
How should the can be stored?
Unopened, in a dry location, with optimal storage at 8 °C to 21 °C. It is pressurised, so keep it out of sunlight and below 50 °C.
