Type
Suggested use
As a pit filler or grout for badly pitted steel or other applications that require a high performance, chemically resistant coating system.
Limitations
Not suitable for immersion in some highly polar solvents. 230°F (110°C) in immersion: 320°F (160°C) gaseous. Maximum thickness in one layer is 6mm.
Health & safety
Before handling or using this product, the material safety data sheet should be
read and all precautions observed.
Surface preparation
The surface to be coated should be free from grease etc. Metal should be grit blasted to a minimum SSPC-SP10 (ISO8501-1 Sa 2½ near 3) or equivalent. (Please refer to Corrocoat data sheet SP1). All blast residues must be removed by sweeping or blowing clean and vacuuming where necessary.Application to the substrate should then take place as soon as possible. For full surface preparation details see relevant surface preparation specification sheets. Alternatively, Corrofill VE may be applied over a Polyglass primer applied in accordance with that product data sheet.
Mixing ratio
Corrofill VE can be catalysed using P2 catalyst within the ratios
of 100:1 PBW base to catalyst to 100:2 PBW base to catalyst. The ratio should always be within these limits, 2%
addition of catalyst being the norm, 1% being used at ambient
temperatures above 82°F (28°C) or where film thickness applied exceeds 5mm.
Thinners
DO NOT THIN. NO DILUENT OR THINNER MAY BEUSED. The addition of Styrene may adversely affect the chemical resistance of this product. Styrene should not be added without consulting Corrocoat USA.
Packaging
1 Gallon and 5 Gallon Kits
Color
Dark grey.
Theoretical spreading rate
40 sf / gallon at 40 mils dft (1.3 kg/m² @ 1mm DFT).
Practical spreading rate
Regular surfaces, e.g. new steel – 25 sf / gallon (1.9kg/m² @ 1mm DFT. Irregular surfaces, e.g. badly pitted steel – 3kg/m2 @ 1mm DFT).
Cure time
At 68°F (20°C), 90% cure attained in 8 hours. Full cure forchemical resistance will require 6 days at 68°F (20°C). Cure times will be shortened, and the degree of final cure improved by post curing at elevated temperatures.
Mixing
Weigh out only the proportion of material which can be used within the pot life and place into a mixing container. Measure the correct proportion of catalyst for the base amountand carefully add this to the base using a suitable clean implement. Mix thoroughly then add dye if required and mix to an even color. After stirring it is advisable to remove the contents from the mixing container into a shallow receptacle and remix.
Pot life
50-60 Minutes at 68°F (20°C). Pot life will be shorter at higher temperatures and longer at lower temperatures. Wherehigh temperatures are encountered, refrigerate material before use or else seek the advice of Corrocoat USA.
Application equipment
Short hair stiff brush, trowel or scraper blade.
Application
Using application implement, the catalyzed material should be vigorously worked into the surface profile, ensuring that the maximum possible wet out of the surface is achieved. Following this procedure, the coating thickness may be built up in thickness. The material may be applied at DFT’s of up to 6mm but this thickness should not be exceeded in a single coat to avoid shrinkage and high exotherm.

Tensile strength
3,627 psi (255 kg/cm²) (full cure).
Adhesive strength
3,555 psi (250 kg/cm².)
Shrinkage ratio
6.5% dependent upon speed of cure.
Hardness

Overcoating
May take place as soon as the previous coat has gelled sufficiently to resist movement of next application and while still tacky. Maximum overcoating without treatment is 4 daysat 68°F (20°C) (shorter at ambient temperatures above 86°F (30°C).
