wo-component epoxy-based primer
with high solids
– Thinner for Mapecoat Rustop CI 100
WHERE TO USE
Mapecoat Rustop CI 100
Adhesion promoter with high rust-prevention properties
for metallic surfaces, including vertical surfaces,
applied prior to coating surfaces with Mapegum EPX,
Mapegum EPX-T and epoxy-based products.
Rustop CI 100 Thinner
Solvent-based mixture for diluting
Mapecoat Rustop CI 100.
Some application examples
• Anti-rust coating for metallic structures, including
those located in coastal areas.
• Protection for metallic sheet metal used in the civil
and industrial building sectors.
TECHNICAL CHARACTERISTICS
Mapecoat Rustop CI 100 is a two-component,
epoxy resin-based primer with high solids according to
a formula developed in the MAPEI research laboratories.
RECOMMENDATIONS
• Dilute Mapecoat Rustop CI 100 with
Rustop CI 100 Thinner only.
• Do not apply Mapecoat Rustop CI 100 on oxidised,
rusty or dirty surfaces or on surfaces with traces of
old coating materials.
• Do not apply any coating over Mapecoat Rustop CI 100
until the solvents contained in the product have
completely evaporated (never use the “wet on wet”
method).
• Drying and painting times refer to the dry thicknesses
recommended. Thicker layers, poor ventilation and
lower surrounding temperatures increase the amount
of time required for the product to catalyse correctly.
In such cases, the solvents may not evaporate
completely and the waiting time required before
painting or coating the product will be longer.
• Only apply Mapecoat Rustop CI 100 when the
temperature of the surface to be coated is at least
+3°C higher than the dew-point temperature to
prevent the product becoming detached.
APPLICATION TECHNIQUE
Preparation of the substrate
All surfaces to be treated must be clean, sound, dry
and free of all traces of dust, oil, grease or wax. It is
very important that the surface is prepared correctly to
guarantee correct application and the best performance
of the product. The most suitable preparation method
is sand-blasting, which removes all traces of old paint,
rust, grease and encrustations from the surface. This
type of treatment allows the surface to be brought down
to a bare metal finish (SA 2½).
Preparation of the mixture
Pour component B of Mapecoat Rustop CI 100 into
component A and mix with a drill at low speed with
a mixing attachment until completely blended. The
contents of each component of Mapecoat Rustop CI 100
are pre-dosed. Do not use partial quantities of the

components to avoid making dosage errors
when mixing; this could lead to incorrect/
incomplete hardening of the product.
If partial quantities of the components are
used, mix each component separately prior
to blending them together. Use precision
electronic scales to dose each component at
a ratio of A : B = 5.2 : 5.5 parts in weight, mix
the two components and then blend them
together.
After blending the two components, let the
mix stand for 10-15 minutes before use.
If necessary, Mapecoat Rustop CI 100 may
be diluted with Rustop CI 100 Thinner at a
rate of 3% to 5% in weight, depending on the
application technique used.
Recommended average dry film thicknesses:
– galvanized substrates: 75 μm;
– carbon steel: 150 μm;
– substrates in severe conditions and
immersed substrates: 1 or 2 coats, total
thickness 250 μm.
Application of the mix
Apply Mapecoat Rustop CI 100 with a
medium-haired roller or brush for small
surfaces or areas that just need patching
up, or with airless spray for large surfaces.
Apply the mix when the surrounding
temperature is between +10°C and +30°C.
Do not apply if the temperature is around
dew-point temperature.
Rustop CI 100 Thinner:
from 3% to 5% in weight of
Mapecoat Rustop CI 100, depending on
application method used.
Cleaning
Clean tools used to prepare and apply
Mapecoat Rustop CI 100 immediately after
use with Rustop CI 100 Thinner or nitro
thinner. Once hardened, the product may
only be removed using mechanical means.
CONSUMPTION
Mapecoat Rustop CI 100:
6.5 m²/kg per 100 μm of thickness.
