Asolvent-free, three-pack polyamine cured epoxy containing high levels of
abrasion resistant filler.

Suggested use

PlasmetWR should be used where abrasion resistance is
a prime requirement. WR works well both in immersed and
non-immersed environments, but has shown particularly
good results in dry abrasion. Suggested areas of application
are coal bunkers, pulverised fuel lines and ash handling

Surface preparation

WR can be applied to decontaminated and wire brushed
surfaces, however to obtain optimum adhesion the substrate
should be grit blasted to SSPC-SP10 (ISO 8501-1 Sa 2½)
or equivalent with 3 mil (75 micron) profile.

Application equipment

Prime Coat: Brush
Build Coat: Trowel or float
Glaze Coat: Brush.


Remove approximately2% of the resin and hardenerand retain
for use as the final glaze coat. Mix together the larger part of
the base and hardener(98%) in a large container capable of
holding all the aggregate.
Using a brush, prime the surface to be coated using the mixed
base and hardener.Mix the required amount of aggregatewith
the base and hardener and apply the coating to the primed
surface. For best results on vertical surfaces work should
start from the bottom using a trowel or float and squeeze the
material firmly on to the substrate, building upwards at all times.Failureto usethis method ofapplication will inevitably
result in droop and sag.
The product may be built up to any desired thickness in
multiple coats,bearing in mind heat generation and hold-up
characteristics. Larger thicknesses may be built by using
meshing techniques; similar to those used in the building
industry for rendering andplastering.
Allow the build coat to cure, then mix the remaining base and
hardener together and apply as a glaze coat. Alternatively,
Plasmet ‘T’ may be utilized as a top coat for this product.

Mixing ratio

Base:Hardener 100:64
NOTE: It is possible to obtain an increase in abrasion
resistance by reducing the aggregate to resin loading to
a ratio of 70:30. However, the vertical hold-up at this level
is poor and therefore this ratio may only be used on flat or
gently inclined surfaces.


The coating may not be applied to overhanging surfaces
without the use of retaining mesh.
