VE Pipe Grade
Product reference: 2/28
Product title: Polyglass VE Pipe Grade
Valid from: 14th August 1997
Last reviewed: May 2019
Type: A two-pack cold cured vinyl ester/acrylic co-polymer enhanced with flaked glass, specifically formulated to be applied using a centrifugal pipe rolling rig.
Immersed environments where superior resistance to chemical attack is required, VE is suitable for most chemical environments within the pH range of 0 to 13 and is unaffected at temperatures up to 194°F (90°C) by demineralized water. It also has excellent resistance to most solvents. May be used in aggressive atmospheric or spillage conditions.
Affected by some highly polar solvents and solutions exhibiting high pH at temperatures above 122°F (50°C).
Health & safety
Before handling or using this product, the material safety data sheet should be read, and all precautions observed.
Metals: Grit blast to SSPC-SP10 (ISO 8501-1 Sa 2½ near 3) or equivalent. For full details refer to Corrocoat Surface Specification SP1.Concrete:Grit blast to remove surface laitance. See Corrocoat Surface Specification SP5.
Specialist pipe rolling equipment.
6 months stored at temperatures below 68°F (20°C) and away from heat sources and direct sunlight. Frequent temperature cycling will shorten storage life. See other information for extension of shelf life.
Unpigmented (Translucent Brown) and Off White only. Other colors are not available and it should be noted that the addition of dyes will adversely affect chemical resistance.
Between 30-120 mils (750-3000 microns) dependent upon environment.
Theoretical spreading rate
54 sf per gal at 30 mils (1.33m²/litre at 750 microns).
This material contains volatile liquid convertible to solids. Volume solids obtained will vary dependent uponpolymerization conditions. Nominally 99.05% of the contents are convertible to solid.
Practical spreading rate
42 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 environmentalconditions, the geometry and nature of work undertaken and the skill and care of application. Corrocoat accepts no responsibility for any deviation from these values.
230°F (110°C) immersed. 347°F (175°C) non-immersed. No known lower limit.
May take place as soon as the previous coat has gelled and while still tacky. Maximum overcoating time is 48 hours. For times in excess of 48 hours and for overcoating on concrete substrates, refer to Corrocoat for special instructions.
With standard inhibitor level, tack free 6 hours, full cure 3-4 days at 68°F (20°C), but may be immersed in many environments after 24 hours.
Methyl Ethyl Ketone, Methyl Iso Butyl Ketone – before gel.
Dependent on intended use and prevailing site conditions, but Polyglass VE Pipe Grade is normally applied in wet films between 40-80 mils (1000-2000 microns). For further details see Polyglass Application Data Sheet.
Mixing ratio / mixing
98:2 base to hardener. For inhibitor use and mixing instructions refer to Polyglass Application Data Sheet.
Variable to suit site conditions, refer to Polyglass Application Data Sheet, typically for Pipe Grade 25-30 minutes at 68°F(20°C).
The performance of Polyglass VE Pipe Grade can be adversely affected by the addition of solvent thinners and their use is prohibited. Thinning can be achieved by the addition of not more than 5:100 styrene monomer to Polyglass Pipe Grade by volume i.e. maximum 0.25-gal (1.25 litres) styrene per5.25 gal (25 litres) Polyglass Pipe Grade. It should be noted that dilution with styrene may affect chemical resistance.
