Thread Sealants
Prevent gas and liquid leaks on metal pipes and joints
Thread sealing is achieved as the anaerobic adhesive cures when confined in the absence of air, and between close metal fitting surfaces. This technology is ideal for joints, which are considered to be dynamic due to vibration, changing pressures or changing temperatures.

When to Use a Thread Sealant
Designed for low and high pressure applications, thread sealants fill the space between threaded parts and provide an instant, low pressure seal. When fully cured, they seal to the burst strength of most pipe systems.

Typical Applications
Typical applications for thread sealants include sealing metal tapered pipe threads and fittings in the chemical processing, petroleum refining, pulp/paper, waste treatment, textile, utilities / power generation, marine, automotive, gas compression and distribution industries. Thread sealers are also recommended for industrial plant and fluid power systems.

Advantages of LOCTITE®Thread Sealants
  • Single-component – clean and easy to apply
  • Do not creep, shrink or contaminate systems
  • Can be used on any size of pipe fitting
  • Replace all types of tape and hemp/paste sealants
  • The seal resists vibration and shock loads
  • Available with major agency approvals
  • Protect mated threaded areas against corrosion
  • Available with potable water and gas approvals
  • Ensures complete contact between threads, 100% seal
  • Designed for high- and low-pressure applications
  • Has controlled strength for ease of disassembly

 

LOCTITE® 567™ and LOCTITE®577™ Thread Sealants Offer Powerful Performance
No drips, no leaks, no unscheduled downtime — the next generation of LOCTITE thread sealants.

Why Using LOCTITE® Thread Sealants Is Better Than Traditional Sealant Types
  • Solvent-based sealing compounds can shrink during cure as solvents evaporate. Fittings must be re-torqued to minimize voids. They lock the assembly by a combination of friction and deformation.
  • PTFE tape lubricates in off direction, allowing fittings to loosen under dynamic loads and resulting in loss of clamping force and leakage. Dynamic loads may accelerate creep, causing leakage over time. The lubricating effect of PTFE frequently results in over-tightening of fasteners, adding stress or causing breakage of parts. Application requires good professional skills to avoid stressing fittings or castings.
  • Hemp and paste are slow to apply, are messy to assemble, and interfere with the torque needed to obtain the correct pre-stress. These can require re-work to achieve a 100% seal of the assembly.

 

Anaerobic Adhesives
Prevent metal components from loosening because of vibration and protect joints from corrosion or rust 
Anaerobic adhesives work by completely filling gaps between components. They are typically used to augment the seal or holding force of a mechanically joined assembly. LOCTITE®
anaerobic adhesives include threadlockers, thread sealants, retaining compounds, and gasket sealants.

How LOCTITE® Anaerobic Adhesives Work
Anaerobic adhesives remain liquid until isolated from oxygen in the presence of metal ions. Though anaerobic applications differ widely, in most cases the adhesive provides high shear strength and temperature resistance. Anaerobic adhesives fixture in minutes at room temperature and fully cure within 24 hours. Full cure of anaerobics may be achieved more rapidly using short-term exposure to heat (e.g. 30 minutes at 120°C).

Why Adhesives?
Attention sign manufacturers, your sign assembly just got better! Our extensive product portfolio of 18 adhesives is the ultimate solution for your sign application needs. From construction to installation, we have the right product for every application.

Adhesives and sealants have several beneficial uses in the sign industry. Use adhesives to:

  • Join Dissimilar Substrates
  • Distribute Stresses Evenly
  • Fill Large Gaps
  • Seal and Bond
  • Reduce Labor Costs (welding vs. general labor)
  • Prevent Galvanic Corrosion
  • Absorb Energy
  • Eliminate Drilling/Tapping, Weld Read-Through and Mechanical Fasteners
  • Maintain long-term sealing performance
  • Look Better (Aesthetics)

 

Adhesives vs. Tapes: What’s the Difference?

Liquid adhesives are superior to tapes for many reasons. Here are a few:

  • Repositionability – Tapes are difficult to reposition, which can lead to scrapping material. Liquid adhesives are easy to reposition, reducing waste.
  • Fast Assembly – Liquid adhesives can be applied much faster than tapes, saving time in assembly operations.
  • High Green Strength – As they cure, liquid adhesives become stronger than tapes.
  • Preventing Creep – Liquid adhesives prevent bond lines from separating over time, regardless of how much weight is applied.

 

Why Henkel?
New Technologies

We have new and improved technologies that are well suited for the sign industry:

Universal bonders and TEROSON® MS 5555 NA low cost SMP are both new to the sign industry. We feature two universal bonders and five different SMP products. These products aren’t used by our competitors. At Henkel, we are always thinking forward. We target specific applications where we can succeed and excel.
