CORROGLASS

Corroglass 202

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.

Suggested use

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.

Limitations

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.

Surface preparation

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.

Application equipment

Specialist pipe rolling equipment.

Storage life

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.

Color availability

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.

Recommended DFT

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).

Volume solids

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.

Temperature limits

230°F (110°C) immersed. 347°F (175°C) non-immersed. No known lower limit.

Overcoating

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.

Curing time

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.

Cleaning fluid

Methyl Ethyl Ketone, Methyl Iso Butyl Ketone – before gel.

Application

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.

Pot life

Variable to suit site conditions, refer to Polyglass Application Data Sheet, typically for Pipe Grade 25-30 minutes at 68°F(20°C).

Thinners

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.
