LOCTITE® LB 8150™ is a commercial-grade, heavy-duty anti-seize lubricant paste engineered for demanding industrial, mechanical, and processing environments.
Fortified with graphite, aluminum powder, and extreme pressure (EP) additives, LOCTITE 8150 creates an inert barrier that will not evaporate or harden under severe thermal cycling or extreme friction. It effectively protects threaded fasteners, studs, flanges, and heavy machinery joints from cold welding, galling, seizing, and high-temperature oxidation.
Key Industrial Applications & Benefits
-
Thermal Stability: Protects threaded connections and metal joints exposed to extreme temperatures ranging from -30 °C to +900 °C.
-
Extreme Pressure Resistance: High load-carrying capabilities prevent seizing and galling under high mechanical stress.
-
Corrosion Protection: Shields critical equipment against harsh environment moisture, atmospheric corrosion, and chemical degradation.
-
Easy Disassembly: Eliminates fastener breakage during standard maintenance, reducing downtime in power plants, oil & gas refineries, automotive exhaust servicing, and boiler operations.
-
Surface Preparation: Works seamlessly when parts are clean with Loctite 7063.

Frequently Asked Questions (FAQ)
Q1: What is the maximum service temperature for LOCTITE LB 8150?
A: LOCTITE LB 8150 withstands continuous thermal exposure and peak temperatures up to +900 °C (+1652 °F) without hardening, evaporating, or losing lubricity.
Q2: Is LOCTITE 8150 suitable for stainless steel or reactive piping systems?
A: LOCTITE LB 8150 is ideal for standard steel and alloy threads exposed to high heat. However, it is explicitly not recommended for pure oxygen, oxygen-rich environments, or systems transporting chlorine and strong oxidizers.
Q3: Can LOCTITE 8150 be purchased in wholesale quantities for commercial orders?
A: Yes, Hong Teck Hin offers full tier-based wholesale pricing, bulk packaging, and immediate dispatch options for commercial procurement accounts.
Q4: Does LOCTITE LB 8150 cure or dry hard after application?
A: No, LOCTITE LB 8150 is a non-curing, petroleum-based grease paste designed to remain flexible and effective under extreme operating conditions.
