LOCTITE 5452 is a purple, thixotropic, methacrylate ester acrylic thread sealant liquid designed for threaded fittings commonly found in hydraulic and pneumatic systems. It is useful with dry seal fittings such as O-Ring boss style connectors. It can be used as a sealant on mating surfaces of flare style fittings. It contains no fillers or particles that can interfere with a hydraulic system.

• Suitable for large diameter pipes
• Prevents the rotation that ultimately leads to leakage
• Seals scratches and surface imperfections

LOCTITE®
5452™ is designed for threaded fittings commonly
found in hydraulic and pneumatic systems. The thixotropic
nature makes LOCTITE®
5452™ suitable for large diameter
pipes. This material is useful with dry seal fitings such as
O-Ring boss style connectors, by preventing the rotation that
ultimately leads to leakage. LOCTITE®
5452™ can be used as
a sealant on mating surfaces of flare style fittings to seal
scratches and surface imperfections. It contains no fillers or
particles that can interfere with a hydraulic system.

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. The graph
below shows the breakloose strength developed with time on
3/8 x 16 steel nuts & bolts compared to different materials and
tested according to ISO 10964, pretorqued to 5 N·m.

Cure Speed vs. Activator

Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows the breakloose strength
developed with time using Activator SF 7471™ and SF 7649™
on 3/8 x 16 zinc dichromate nuts and bolts and tested
according to ISO 10964, pretorqued to 5 N·m.

GENERAL INFORMATION

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.

Directions for use:

For Assembly

1. For best results, clean all surfaces (external and internal)
   with a LOCTITE®
   cleaning solvent and allow to dry.
2. If quicker service time is required, use Activator 7471™ or
   7649™ prior to application of sealant and allow to dry.
3. For NPT or other taper joint fittings apply a 360° band of
   sealant to leading threads of the male fitting. For larger
   threads and gaps, adjust the volume of sealant
   accordingly.
4. For ORB & O-Ring Fittings apply a 360° band of sealant
   to the threads for the male fitting. Ensure product is
   applied into roots of the threads and adequate coverage.
5. For JIC Fittings coat the face of the male JIC with the
   sealant. This is applicable for new and damaged fittings.
   Also apply to threads for vibration resistance.

For Disassembly

1. Remove with standard hand tools.
2. Where hand tools do not work because of excessive
   engagement length or large diameters (over 25 mm),
   apply localized heat to approximately 250 °C.
   Disassemble while hot

For Cleanup

1. Cured product is most easily removed with mechanical
   abrasion such as a wire brush and wiped clean with a
   cotton cloth.
2. Fittings if mechanically acceptable can normally be
   reused once cleaned.
