CORROGLASS
600 Laminating Resin
Product reference: 1/14
Product title: 600 Laminating Resin
Valid from: 27th November 1997
Last reviewed: 31 May 2019
Type: A two-pack cold cured Vinyl Ester Laminating Resin.
Suggested use
Use in conjunction with multi-directional roving to construct glass reinforced laminate and repair severely corroded and pitted areas or to offer additional protection in the corners of tankage prior to spray application. See Corrocoat Data Sheets TC1.
Limitations
Not suitable as a protective coating without glass
reinforcement and at films less than 120 mils dft ( 3mm). It is suggested that where this product is used for lamination protection systems a top layer of Polyglass VE at 20 mils dft (500 microns) is applied to reduce permeation.
Health & safety
Before handling this product, the material Health &
Safety Data Sheet for 600 Series should be consulted
and all precautions observed. Only to be applied by
competent, adequately trained personnel.
Surface preparation
Metal Surfaces: Grit blast to SSPC-SP10 (ISO 8501-1
Sa 2½ or near 3) standard or equivalent. For full details
refer to Corrocoat Data Sheet SP1. The laminate will
typically be applied over a primedsurface.
Application equipment
Brush or roller.
Mix ratio
98:2 Base:Hardener.
Pot life
Variable with temperature.
At 68°F (20°C) approximately 20-30 minutes.
Thinners
The performance of 600 Laminating Resin may be adversely affected by the addition of solvent thinners (e.g. Xylene) and their use is prohibited. Should thinning be necessary use only styrene monomer to an absolute maximum of 5% by volume concentration.
Packaging
1 Gallon and 5 Gallon Kits
Storage life
6 Months stored at temperatures below 75°f (24°C) and
away from direct light and sources of heat.
Color
Translucent brown.
Recommended DFT
Dependent upon application and quantity of roving used.
Volume solids
99.5% solvent free.
Practical spreading rate
Dependent on roving used.
Specific gravity
600 Laminating base 0.04 lbs/cubic inch (1.065 gms/cc).
Catalyst type
Methyl Ethyl Ketone Peroxide: Corrocoat Type P2.
Overcoating
May take place as soon as the previous coat has gelled and while still tacky. Maximum overcoating time 72 hours. Please note: Maximum levels refer to ambient temperature of approximately 68°F (20°C). At higher temperatures the maximum overcoating time will reduce significantly.
Once the maximum overcoating time has been reached, the adhesion values attained by any subsequent coat will reduce dramatically. It is important to observe maximum overcoating times and note these will vary with climatic conditions. Any further application of coating at this juncture should be treated as a repair, with the surface flashed over to provide a physical key. Styrene cannot be used to reactivate the surface and may in some cases impair adhesion.
Cure time
Full cure will be obtained in 4-6 days
Cleaning solvent
Acetone, Methyl Ethyl Ketone and Methyl Iso Butyl Ketone prior to gelation
