Type: Two-pack isophthalic polyester acrylic glass flake coating.

Suggested use

Immersed environments such as marine, aqueous, light chemical service and many aggressive atmospheric environments. Can be used as a floor coating and may be applied with skid resistant aggregate.

Health & safety

Consult the Health & Safety data sheet prior to carrying out any work with this product.

Surface preparation

Metals:Grit blast to SSPC-SP10 (ISO standard 8501-1 Sa) or equivalent. (For full details refer to Corrocoat Surface Preparation SP1.)Concrete: refer to Corrocoat data sheet SP5.

Application equipment

Airless pump 45:1 or greater, fit leather seals and remove fluid filters, 10mm diameter (3/8”) nylon lined hoses, large bore gun with 24 to 60 thou reverse clean tip. Typical tip size is 30-35 thou with a 45° fan. The size of tip and fan pattern will vary with the nature of the work. Pressure to suit hose lengths and working conditions. (circa 200bar).


1 Gallon and 5 Gallon Kits

Storage life

Base 12 Months, Catalyst 6 Months stored at temperatures below 68°F (20°C) and out of direct sunlight. Frequenttemperature cyclingwill shorten storage life and may cause condensation polymerization. It is recommended duringextended storage, i.e. greater than 3 months, thatthedrumsbe periodically inverted. See CC Tech Manual (other information) for extension of shelf life.

Color availability

Off white as standard, unpigmented (brown), red oxide, yellow, black and green to order.

Theoretical spreading rate

40 sf per gallon (0.998m² per litre) at 1mm dft

Volume solids

This material contains volatile liquid convertible to solids. Volume solids obtained will vary significantly dependent upon the prevailing polymerization conditions. Nominally 99% of the contents are convertible to solid

Coating adhesion

Greater than 10MPa.

Curing time

Tack free in 5 hours, full cure 7 days at 68°F(20°C). May be immersed in non-chemical aqueous environments immediately after gel.

Cleaning solvent

Methyl Ethyl Ketone, Methyl Iso Butyl Ketone or Acetone prior to gelation.


A single or two coat application directly to steel, generallyat 600um DFT for atmospheric or 850um and above for immersion conditions. PPA primer may be required for logistical purposes

Mixing ratio

For normal applications 98.5:1.5 base to hardener (catalyst P2). At high ambient temperatures inhibitor added and well mixed before the hardener is added may be used to retard the pot life. Below 50°F (10°C) the cure of the product may beimproved by use of Catalyst P4, mix ratio 97.5:2.5 base to hardener.

Pot life

Generally, 50-60 minutes at 68°F (20°C). The pot life will vary substantially with temperature. Inhibitor may be used at temperatures above 69°F (21°C), special catalystmay be provided for use in low temperature applications.See above


The performance of this product will beadversely affected using solvent based thinners. When necessary thinning may be achieved by the addition of not more than 5% by volume of styrene to Polyglass. Thinning for normal applications willnot benecessary.The addition of styrene may adversely affect the chemical resistance of the product and hold-up will also be affected.

Practical spreading rate

43 sf per gal at 30 mils (1.06m2/litre at 750 microns). NOTE: This information is given in good faith, but rate may vary significantly dependent upon environmental conditions, the geometry and nature of work undertaken and the skill and care of application. Corrocoat accepts no responsibility for any deviation from these values

Specific gravity

Base: 0.04lbs/cubic inch (1.218 gcm-3) Hardener: 0.03lbs/cubic inch(1.07 gcm-3

Flash point

78°F (26°C). 

Catalyst type

Methyl Ethyl Ketone Peroxide type P2.At temperatures below 50°F (10°C) use peroxide type P4.

Mixing ratio

98.5: 1.5 base to hardener.<10°C, P4 97.5: 2.5 base to hardener.


Approximately 40 Barcol. May be higher in ideal conditions.

Abrasion resistance

224.2 mgm loss/1000 cycles/1000gm load H18 wheel.


May take place as soon as the previous coat has gelled but while still tacky. Maximum overcoating time 72 hours but maximum overcoating time will reduce significantlyat high ambient temperature or in strong sunlight.
