Polyglass VEF WR

Product reference: 2/58

Product title: Polyglass VEF WR

Valid from: 23rd November 2007

Last reviewed: May 2019

Type: An abrasion resistant glass flake vinyl ester co-polymer. This product is similar to VEF but has abrasion resistant fillers incorporated to improve abrasion and erosion resistance.

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.


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.


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.


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

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.
