Some working environments in construction are hot, causing moisture that can rapidly cure adhesives, while others are cold, which tends to slow cure. Anaerobics are truly extraordinary because they work in the absence of air and in spaces where other adhesives cannot. Anaerobic simply means “without air” and contains a single component called a “monomer”, which is a molecule that can be bonded to identical molecules to form a “polymer”. Different applications can change the formulations slightly, but keeping the chemistry the same prevents corrosion, contaminants, leakage, and loosening nuts and bolts over time.

Anaerobic adhesives are single component adhesives designed to cure in the absence of air and in the presence of metal ions. These adhesives stay liquid until they are isolated from oxygen and in the presence of ions such as iron or steel. Anaerobic adhesives make excellent threadlockers, as the adhesive seeps down in between the threads of the bolt or screw and escapes the oxygen in the air, then reacts with the metal screw and begins to cure.

Threadlockers are anaerobic adhesives primarily used on threaded materials such as bolts and screws that cure at room temperature in the absence of air. Threadlockers completely fill the gaps between mating threads to lock and seal the threads to the substrate.

PACER ISL-71 High-Strength Threadlocker

The PACER ISL-71 high-strength threadlocker offers the strength and durability of an anaerobic, with the cure time of an instant adhesive. Unlike a traditional anaerobic, this threadlocker performs admirably on plating, stainless steel, and even plastics without using surface activators.

Features:

• Will not craze plastics
• Non-surface sensitive
• Can be pre-applied before assembly
• 1-5-minute handling time
• 80% cure in 15-30 minutes

PACER ANL-22 Low-Strength Removable Threadlocker

The PACER ANL-22 Low-Strength Removable Threadlocker is a special type of anaerobic threadlocker in that its low strength allows for disassembly with basic hand tools. This threadlocker is formulated for use in sealing, joining, and fastening metal components with small screws (under ¼” diameter).

Features:

• Oil tolerant
• High temperature resistance
• Wicking-grade threadlocking compounds
• One-year shelf life
