Loctite Lb 8040 Freeze & Release Formulation Spray Lubricant 310g

LOCTITE® LB 8040™ (also known as Loctite Freeze & Release) is a commercial-grade mineral oil formulation engineered as a rapid rust treatment to free rusted, corroded, and seized parts. Utilizing an advanced shock-freezing mechanism, this industrial spray lubricant instantly cools components down to -43°C. This extreme temperature drop induces microscopic cracks in the dense layer of rust, allowing the active lubricating ingredients to wick directly into the corrosion via capillary action. As a trusted industrial supplier,

Released fasteners and machinery components remain shielded by a thin, durable film that provides ongoing lubrication and corrosion prevention.

Key Benefits & Features

• Shock-Freezing Technology: Drops temperature instantly to -43°C to fracture heavy rust layers.
• Capillary Penetration: Low-viscosity mineral oil wicks deeply into seized threads and joints.
• Corrosion Protection: Leaves a persistent protective film to prevent secondary rust formation.
• Microbial Resistance: Highly resistant to micro-organisms, bacteria, and fungi; completely bactericide-free.
• Operational Efficiency: Low-foaming properties with universal application across standard metal substrates.

Technical Specifications

Directions for Industrial Application

1. Remove heavy dirt and loose rust scaling from the metal parts.
2. Shake the aerosol can thoroughly. Spray at a distance of 10 to 15 cm onto the seized fastener for 5 to 10 seconds.
3. Allow the formulation to react for 1 to 2 minutes to ensure complete capillary wicking before attempting to release the part.
4. Repeat the application if dealing with severe, long-term seizing.

Frequently Asked Questions

How does the freezing mechanism in LOCTITE LB 8040 free seized bolts?

LOCTITE LB 8040 delivers a concentrated stream of lubricant that instantly chills metal components down to -43°C. This rapid thermal shock causes the metal and rust layers to contract at different rates, creating microscopic fractures in the rust. The low-viscosity mineral oil then uses capillary action to seep into these cracks, lubricating the threads from the inside out.

Is LOCTITE LB 8040 suitable for food-grade environments or pure oxygen systems?

No. LOCTITE LB 8040 is an industrial-grade mineral oil formulation and is not recommended for use in pure oxygen or oxygen-rich environments. It should also not be used as a sealant or lubricant for chlorine or other strong oxidizing materials. Always consult the technical data sheet and SDS for specific chemical compatibility.

What are the storage temperature requirements for LOCTITE LB 8040?

To preserve the physical and chemical properties of the formulation, the product must be stored in its unopened container in a dry location at an optimal temperature range between 8 °C and 21 °C. Storing the aerosol cans below 8 °C or above 28 °C can permanently degrade product performance.
