Devcon Wear Guard™ High Temp

Devcon Wear Guard™ High Temp

Ceramic bead filled epoxy system with
outstanding abrasion resistance for
high temperature service conditions.

They are also known as  :
High temperature metal Abrasion protection
Metal abrasion protection
Metal abrasion resistant coating
Metal abrasion resistant paint for metal
Abrasion resistant coating for steel
Wear resistance coating materials

RECOMMENDED APPLICATIONS

• Repairs to ash handling systems
  and scrubbers
• Extends equipment operating life
• Prevents wear on metal surfaces that
  are exposed to abrasion and erosion
  such as chutes and launders
• Non sag formulation
• Protecting flanges and elbows
• Lining bins and hoppers

APPLICATION INFORMATION

CURE

A 5mm thick section of Wear Guard High Temp 450 will
harden at 25ºC in 2-3 hours. The material will be fully cured
in 16 hours. The actual cure time of epoxy is determined by
the mass used and the temperature at the time of repair.

SURFACE PREPARATION

Proper surface preparation is essential to a successful
application. The following procedures should be considered:

• All surfaces must be dry, clean and ideally roughened or
  abrasive blasted to create a profile.
• If surface is oily or greasy use MEK or similar solvent to
  degrease the surface.
• Remove all paint, rust and grime from the surface by
  abrasive blasting or other mechanical techniques.
• Aluminium repairs: Oxidation of aluminium surfaces will
  reduce the adhesion of an epoxy to a surface. This film
  must be removed before repairing the surface, by mechanical
  means such as grit-blasting or chemical means.
• Provide a “profile” on the metal surface by roughening the
  surface. This should be done ideally by grit blasting
  (8-40 mesh grit), or by grinding with a coarse wheel or
  abrasive disc pad. An abrasive disc may be used provided
  white metal is revealed. Do not ’feather edge’ epoxy
  materials. Epoxy material must be ’locked in’ by defined
  edges and a good 3-5 mil profile.
• Metal that has been handling sea water or other salt
  solutions should be grit blasted and high pressure water
  blasted and left overnight to allow any salts in the metal
  to ’sweat’ to the surface. Repeat blasting may be required
  to ’sweat out’ all the soluble salts. A test for chloride
  contamination should be performed prior to any epoxy
  application. The maximum soluble salts left on the substrate
  should be no more than 40 p.p.m. (parts per million).
• Chemical cleaning with MEK or similar solvent should
  follow all abrasive preparation. This will help to remove
  all traces of sandblasting, grit, oil, grease, dust or other
  foreign substances.
• Under cold working conditions, heating the repair area to
  38ºC-43º C immediately before applying any of Devcon
  Epoxies is recommended. This procedure dries off any
  moisture, contamination or solvents and assists the epoxy
  in achieving maximum adhesion to the substrate.
• Always try to make the repair as soon as possible after
  cleaning the substrate, to avoid oxidation or flash rusting.
  If this is not practical, a general application of FL-10
  Primer will keep metal surfaces from flash rusting.

MIXING

For the Wear Guard High Temp, add the hardener to the
resin then mix thoroughly using a suitable mixing paddle
or suitable size jiffy mixer. Mix in such a fashion that the
material is thoroughly dispersed from top to bottom of the
container until homogenous.

APPLICATION

Spread the material over the prepared surface with a putty
knife or spatula pressing firmly into all cracks and voids to
ensure maximum surface contact and avoid trapping air.
A film of up to 20 mm can be applied in one coat if required
even onto vertical surfaces without sagging. It is preferable,
where a thick layer is required, to first apply a 5~mm coat
and then a second coat just before the first is cured to get
the main build to the desired thickness.
Where high temperature duty is desired the following heat
cure regime should be followed; material should be cured at
room temperature for 2.5 hours followed by 4 hours at 90oC.

SHELF LIFE & STORAGE

A shelf life of 3 years from date of manufacture can be
expected when stored at room temperature (22ºC) in their
original containers
