Type
Areas requiring abrasion (and chemical) resistance. This
material has been used in cyclones, chemical process
vessels, sugar beet pulping drums etc. It is also useful for
building up damaged areas of pump impellers and casings
where impact or abrasion are prevalent.
Before handling or using this product the material safety data
sheet should be read and all precautions observed.
To obtain optimum adhesion the substrate should be grit
blasted to SSPC-SP10 (ISO 8501-1 Sa 2½) or equivalent
with 3 mils (75 micron) profile. If grit blasting is not
possible, smooth surfaces should be roughened and
scored by grinding to give the coating a key. Under these
conditions there will be some reduction in adhesion
properties. A release agent should be used for any
surface to which the coating should not adhere.
Trowel, putty knife, stiff brush or other suitable implement.
This material is intended for application at thicknesses between
60 – 240 mils (1.5 to 4mm). It is not normally applied at less
than 1mm thickness but can be built up to any desired
thickness provided care is taken to avoid pronounced
exothermic temperature rises. Material should onlybe applied
when thesurface temperature is between 46-104°F (8- 40°C).
The surface temperatureshould be 41°F (5°C) above dew
point and humidity below an RH value of 90%. It is advisable
to check for ‘amine bloom’. Where this is suspected by
visual appearance or wherethe environmental and ambient
temperatures are outside the above limits. A suitable ‘bloom’
test kit may beused.
6 parts base to 1 part activator by weight.
Remove lids from both components A-Activator and B-Base
and scoop out all of component A putting into component B.
Mix thoroughly, ensuring that no unmixed material remains.
Remove all mixed material from base tin and remix on a
clean flat surface or shallow receptacle. After mixing, the
material remains usable for a limited period dependent upon
temperature, after which time application becomes difficult.
Mix only sufficient material that can be applied with the
limited pot life.

To increase pot life at high ambient temperatures
refrigerate material prior to use to a minimum temperature
of 50°F (10°C). Gel times will vary depending on
temperature and quantity.
Maximum over-coating time is 12 hours at 68°F (20°C).
The minimum over-coating time is 1 hour at 68°F (20°C)
(2mm coating thickness). At different temperatures these
times will vary, being shorter at higher temperatures and
longer at lower temperatures. Amine bloom may cause
intercoat adhesion failure. Refer to ‘Application’ above.
24 hours at 68°F (20°C).
Although the cold cured properties of this material are
excellent, they may be improved further by post curing. This
can be achieved by applying heat at 140-212°F (60-100°C)
for periods up to 24 hours at which time maximum possible
cure will have been attained. Post cure for shorter periods
will also improve the characteristics of this material.
DO NOT THIN. Any addition of solvent will be detrimental to
performance.
