Light duty immersion and atmospheric conditions or as a
surface veil for heavy duty grades.

Not suitable for some highly polar solvents.

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

Metals: Grit blast to SSPC-SP10 (ISO standard 8501-1 Sa
2½ near 3) or equivalent. (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. Corroglass 652 can be applied directly to the
substrate, however, it is more often applied as part of a
600 series system along with Corroglass 602 and 632, in
which case Corroglass 632 is generally used as the
primer.

Brush, Roller, Trowel or Special Spray

As a surface veil in a single coat of approximately 8
mils (200 microns) or as required.
When used direct to substrate, use multiple coats to achieve desired thickness. A minimum DFT of 14 mils (350 microns) is
recommended.
When applying, each subsequent coat of material should be
of a different color to the previous one to ensure full and
even coverage. Only the recommended dye for the product
should be used. 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 not detrimental to
coating performance.

Corroglass 652 can be catalyzed within the ratios of 100:1
parts base to catalyst by weight to 100:3 parts base to
catalyst by weight. The ratio should always be within these
limits, 2% addition of catalyst being the norm with a reduction
being made for high ambient temperatures.

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.

25 to 30 minutes at 68°F (20°C). Pot life will be shorter at
higher temperatures and longer at lowertemperatures.Where
higher temperaturesareencountered,refrigeratematerialbeforeuse
or seek the advice of Corrocoat USA for availability of
inhibitor or material with longer pot life.

Corroglass 652 is adversely affected by the addition of
solvents and their use is prohibited. Styrene may be used
as a thinner up to a maximum addition level of 5%, but the
addition of Styrene may substantially affect the chemical
resistance of this product. No other diluents or thinner
should be used. The use of acetone or similar thinners in
Corroglass will severely affect productperformance.
