Health & safety
Before handling or using this product, the material safety data sheet should be read, and all precautionsobserved.
Metals:Grit blast to SSPC-SP10 (ISO 8501-1 Sa 2½) standard. For full details refer to Corrocoat Surface Specification SP1.Concrete:grit blast to remove surface laitance. See Corrocoat Surface Specification SP5.
For standard Polyglass:Graco King 45:1 or similar airless pump, 10mm diameter (3/8”) nylon lines. Large bore mastic type gun with 30 to 60 thou reversible or titan adjustable tip. As a guide, a typical tip size would be 31-35 thou with a 60° fan pattern. The size of tip and fan pattern will vary dependent upon the nature of the work.For Polyglass HA: brush, roller or trowel.
Off white as standard, Green, Yellow, Red Oxide and Black to order.
30 mils (750 microns) in atmospheric and aqueousconditions. 40 mils (1000 microns) in marine conditions. 60 mils (1500 microns) plus in highly corrosive conditions
Theoretical spreading rate
54 sf per gallon 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 99.95% of the contents are convertible to solid.
Practical spreading rate
43 sf per gallon at 30 mils (1.06m2/litre at 750 microns). NOTE: This information is given in good faith but may increase dependent upon environment conditions, the geometry and nature of work undertaken and the skill and care of application. Corrocoat accepts no responsibility forany deviation from these values.

Methyl Ethyl Ketone Peroxide type P2.
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 8 hours.
Dependent on intended use and prevailing site conditions, Polyglass is normally applied in wet films between 20-40 mils (500-1000 microns). Polyglass Primer PPA should be used where advised. For further details see PolyglassApplication Data Sheet.
98:2 base to hardener. For use on inhibitor and mixing instructions refer to Polyglass Application Data Sheet.
Variable to suit site conditions, refer to Polyglass Application Data Sheet.
The performance of Polyglass 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 by volume i.e. maximum0.25-gallon (1.00 litre) styrene per 5.25-gallon (20 litres) Polyglass.
