Suggested use
Immersion environments where superior resistance to chemical attack and erosion resistance are required. VEF WR
is suitable for chemical environments within the full pH range, it has excellent resistance to a wide range of chemicals and good resistance to many solvents.
Health & safety
Before handling or using this product, the material safetydata sheet should be read
and all precautions observed.
Chemical resistance
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.

Application equipment
Airless pump of 45:1 ratio or greater. Fit leather and PTFE seal combination and remove all fluid filters. 10mm diameter(3/8”) nylon lined hose with 6mm whip end, large bore gun with reverse clean spray tip. Typical tip size is 28 to 48thou with a 45° to 60° fan. Size of tip and fan angle will varydependent upon the nature of the work. Note: Tipwear will be high. Pressure to suit hose lengths and working conditions. (circa 200bar).Brush application; may be brush applied
onto small areas with care.
Application
Dependent on intended use and site conditions, Polyglass VEF WR is normally applied direct to the surface wet on wet at films between 20-48 mils (500 and 1200 microns). Single coat applications are acceptable. Where logistics demand, primer PPA may be used or PPV for temperaturesover 185°F (85°C). For further details see PolyglassApplication Data Sheet.
Recommended DFT
Between 20-118 mils (500 and 3000 microns) dependent upon duty and environment. This material is a barrier coating and the thickness needed is dependentupon service conditions.
Mixing ratio
98:2 base to hardener. For inhibitor use and mixing instructions refer to Polyglass Application Data Sheet. Adding inhibitor after the catalyst will ruin the product.
Pot life
Circa 50 minutes at 68°F (20°C) but may be varied by
use of inhibitor or by special manufacture. For low
application temperatures,refertoPolyglass data sheet.
Thinners
Polyglass VEF is adversely affected by the addition of
solvents and their use is prohibited. Thinning can be
achieved by the addition of no more than .25 gal (1 litre) of
styrene monomer per 5.25 gal (20 litres)of Polyglass. It should
be noted that dilution with styrene will affect hold-up and
chemical resistance.
Packaging
1 Gallon and 5 Gallon
Storage life
Base and catalyst (Hardener) 6 months, stored at
temperatures below 68°F (20°C) and 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.
Color availability
Std. Off White. Other colors may be available on request.
Theoretical spreading rate
54 sf per gal at 30 mils (1.33m²/litre at 750 microns
Volume solids
This material contains volatile liquid convertible to solids. Volume solids obtained will vary dependent
uponpolymerization conditions. Nominally 99% of the product is convertible to solid.
Specific gravity
Polyglass base:0.05lbs/cubic inch (1.25gms/cc). Hardener: 0.03lbs/cubic inch (1.07 gms/cc.)
Catalyst type
Methyl Ethyl Ketone Peroxide, type P2-45.
Practical coverage 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, nature of work undertaken and the skill and care of application. Corrocoat accepts no responsibility for any deviation from this value.
Mixing ratio

Temperature limits
230°F (110°C) immersed. 329°F (165°C) non-immersed. No known lower limit.
Abrasion resistance
122 mg loss/1000 cycles/1000 gm load. (H18 wheel).
Overcoating
It is important to observe maximum overcoating times and note these will vary substantially with climatic conditions. Minimum, as soon as gel has occurred and whilst still tacky. Maximum, at 68°F (20°C) 48 hours. Strong ultra– violet/sunlight will substantially reduce overcoating time. Once maximum overcoating time has been reached, adhesion values attained by anysubsequent coat will reduce dramatically. Should this
occurovercoating should be treated as a repair, with the coating flash blasted to provide a physical key. Styrene cannot be used to reactivate the surface of this product and mayimpair adhesion. Take care to avoid. Styrene cannot be used to reactivate the surface of this product and may impair adhesion. Take care to avoid contamination before application of subsequent coats. Ensure ventilation during cure.
