Permatex 59235 High Temperature Thread Sealant 50ml

Permatex 59235 High Temperature Thread Sealant 50ml

Permatex High Temperature Thread Sealant with PTFE
is formulated for fast, responsive curing on metal pipe threads
and fittings. This sealant is a smooth, white paste-like
compound that controls lubricity to assist assembly and torque
tightening. Permatex High Temperature Thread Sealant
replaces tapes or pipe dopes. It cures rapidly to withstand
10,000 PSI within 24 hours. Prevents galling and protects
mated threaded surfaces from rust and corrosion. The
product cures when confined in the absence of air between
close fitting metal surfaces. This product may not be
compatible with some thermoplastic materials.

PRODUCT BENEFITS

• Quick fixture time
• Prevents galling and corrosion
• Controlled strength
• Temperature and solvent resistance
• Immediate low pressure sealing
• Contains PTFE

TYPICAL APPLICATIONS

Recommended for sealing metal tapered pipe threads and
fittings up to 5cm (2 inches) National Pipe Thread (NPT) for
industrial applications in the chemical processing, petroleum
refining, pulp/paper, waste treatment, textile, utilities/power
generation, marine, automotive, industrial equipment, gas
compression and distribution industries. It is also
recommended for industrial plant fluid power systems.

• Stainless steel fittings
• Head bolts into through holes
• Oil PSI sending units/sensors
• Fuel fittings
• Oil and coolant lines
• Hydraulic line fittings
• Brake fittings
• Transmission fluid fittings
•  PTO fittings
• Air conditioning fittings

DIRECTIONS FOR USE

1. For best performance, surfaces should be clean
   and free of grease.
2. Product should be applied to the thread
   engagement area in sufficient quantity to fill all
   engaged threads
3. Use accepted trade practices to assemble and
   wrench-tighten fittings until proper alignment is
   obtained.
4. This product performs best in thin bond gaps
   (0.05mm).
5. Very large thread sizes may create large gaps that
   will affect cure speed and strength.
6. For maximum pressure and solvent resistance,
   allow at least 24 hours for the product to fully cure
   before filling and pressurizing system.
7. This product is designed to give controlled friction
   (torque/tension ratio) during assembly.

TYPICAL CURING PERFORMANCE

Cure speed vs. substrate

The rate of cure will depend on the material used. Permatex
High Temperature Thread Sealant will react faster and
stronger with Active Metals. However, Inactive Metals will
require the use of an activator (Surface Prep) to obtain
maximum strength and cure speed at room temperature.

Cure speed vs. temperature

The rate of cure will depend on the ambient temperature. Full
cure is attainable in 24 hours at room temperature, 22°C
(72°F), or 1 hour at 93°C (200°F).

Cure speed vs. activator

Where cure speed is unacceptably long, or large gaps are
present, applying an activator (Surface Prep) to the surface
will improve cure speed. The graph below shows the shear
strength developed with time on 1/2” NPT fittings using
Permatex Surface Prep Activator.

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
Material Safety Data Sheet, (MSDS).

STORAGE

Products shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°C and 28°C
(46°F and 82°F) unless otherwise labeled. Optimal storage is
at the lower half of this temperature range. To prevent
contamination of unused product, do not return any material to
its original container.
