Suggested use

This product is outstanding in its performance and can be
used in many areas of application to build thick layers, it
can also be moulded and machined. Corroglass 602 has
the same field of application as Corroglass 202 but with a
much better resistance to many chemicals and solvents, as
well as increased temperature resistance. 600 series
materials havegreaterresistancetohydrolysis,theyare
suitable for demineralized or distilled water applications.


Not suitable for some highly polar solvents.

Chemical resistance

Refer to the chemical resistance list. Affected bysome
highly polar solvents and some solutions having a high pH
above 122°F (50°C).

Health & safety

Before handling or using this product, the material safety
data sheet should be read, and all precautions observed.

Surface preparation

Metals: Grit blast to SSPC-SP10 (ISO standard 8501-1
Sa 2½ near 3). For full details refer to Corrocoat Surface
Preparation SP1.
Concrete: refer to Corrocoat SP5.
Coating of the substrate should then take place as soon
as possible. Although 602 can be applied directly to the
substrate, its wet-out properties are poor and in order to
reduce application time of the first coat, it is advisable to use
Corroglass 632 as a primer under thismaterial.


Weigh out only the proportion of material which can be used
within the pot life and place into a suitable mixing container.
Measure the correct proportion of catalyst for the amount of
base and carefully add this to the base, using a suitable clean
implement. Mix thoroughly then add dye where necessary
and mix to an even color. After stirring it is advisable to
remove the contents from the mixing container on to a clean
flat surface or shallow receptacle andremix.

Pot life

40 to 50 minutes at 68°F (20°C). Pot life will be shorter at
higher temperatures and longer at lower temperatures.
Where high temperaturesareencountered,refrigerate
materialbeforeuse or seek the advice of Corrocoat USA for
availability of inhibitor or material with longer pot life.


Corroglass 602 is adversely affected by the addition of
solvents and their use is prohibited. Where a less viscous
material is required, the addition of 632 will lower the
viscosity without significant effect on performance. No other
diluents or thinner should be used. The use of acetone
or similar thinners in Corroglass will severely affect product

Practical spreading rate

Regular surfaces e.g. new steel – 25 sf per gallon at
40 mils dft, minimum.
Irregular surfaces e.g. badly pitted steel – 15 sf per gallon at 40
mils dft.

dependent upon environment conditions, thegeometry
and nature of work undertaken and the skill and care of
application. Corrocoat accept no responsibility for any
deviation from these values.

Mixing ratio

100:1 to 100:2 base to catalyst.

Thermal conductivity

0.398 W/m°K

Mixing ratio

Corroglass 602 can be catalyzed within the rations of 100:1
BASETO CATALYSTBYWEIGHT.The ratio should always
be within these limits, 2% addition of catalyst being the norm
with a reduction being made for high ambient temperatures.

Dielectric strength

Approximately 26 kV at 1mm film. Arc resistance 60 seconds


For best surface finish use pure carbide or carbide tips with
small radius and neutral rake. Material has similar machining
characteristics to those of grey cast iron. Tool must be kept
sharp. Run out will occur due to tool wear over relatively short
distances, especially when facing from OD to center. Clean
water may be used as lubricant or dustdamper.

Cure time

At 68°F (20°C), 90% cure will be attained within 8 hours.
Full cure for chemical resistance will be 6 days. Cure
time may be shortened and a beneficial increase in final
cure may be attained by post heat treatment. Consult
Corrocoat USA for specific information.
Although not cured, after gelling this material may be
immersed in some environments without detriment to the


Corroglass 602 should be applied to a properly prepared
substrate and preferably over the top of 632, as the main
build coat in the predominant 600 series specification: – (1
coat 632, 2 coats 602, 1 coat 652 to a total DFT of 1500
microns). 602 can be applied at varying thicknesses being
capable of applied between 8-118 mils (200-3000
microns) without sag in a single film. Final thickness will
vary to suit service environment.
There is no maximum to the thickness of Corroglass 602 and
voids/landings etc can be built up several centimetres thick.
However, single coat applications should not normally exceed
After applying this material to the substrate and ensuring the
film is of even thickness, the surface should be lightly brushed
or trowelled with Styrene Monomer, catalysed with P2 at the
2% level, to close any voids and assist with orientation of the
flake structure.
However, care must be taken to avoid the excessive use
of Styrene which may degrade the surface layer or cause
problems with inter-coat adhesion. Where it is necessary
to use dye, only the recommended dye for the product
should be used and dye must be used sparingly so that
only the necessary amount is used to give good
distinction from the previous application.Dyes can affect chemical and corrosion resistance in some
environments and the advice of Corrocoat USA should be
sought where the material will work close to either its
chemical resistance or temperature limit. In some
environments, dyes are not color stable and a change in
color may take place in service which is rarely detrimental to
coating performance.

Application equipment

Brush, trowel or float.

Mixing ratio

Corroglass 602 can be catalyzed within the rations of 100:1
BASETO CATALYSTBYWEIGHT.The ratio should always
be within these limits, 2% addition of catalyst being the norm
with a reduction being made for high ambient temperatures.

Storage life

Base and catalyst (Hardener) 6 months, stored at
temperatures below 68°F (20°C), away from heat sources
and out of direct sunlight. Frequent temperature cycling will
shorten storage life. See ‘other information’ in the
Corrocoat ‘Tech Manual’ for extension of shelf life.

Unpigmented (Translucent Brown) or Pigmented White.
Dyes can be used to effect color change where chemical
resistance is not of paramount importance.

any desired thickness for repair.

Temperature limits

Dependent upon environment:


May take place as soon as previous coat has gelled
sufficiently to resist movement of next application and while
still tacky. Maximum overcoating without treatment 2 days.
Shorter at ambient temperatures above 86°F (30°C) and in
strong sunlight. Once the maximum overcoating time has
been reached, the adhesion values attained by any
subsequent coat will reduce dramatically. It is important to
observe maximum overcoating times and note these will
vary with climatic conditions.
Any further application of coating at this juncture should be
treated as a repair, with the surface flashed over to provide
a physical key. Styrene cannot be used to reactivate the
surface and may in some cases impair adhesion.

Cleaning fluid

Acetone or Methyl Ethyl Ketone before gel.
