A two-pack cold cured polyester/acrylic co-polymer enhanced with flaked glass.
Immersion; such as marine, hydrocarbon, aqueous and corrosive chemical environments. Also applicable where aggressive atmospheric conditions appertain.
Not suitable for protection against polar solvents, demineralized water and where pH conditions are below 1 or above 12.
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) 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.
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 Polyglass Application Data Sheet.
12 months stored at temperatures below 75°F (24°C) and away from heat sources and direct sunlight. Frequent temperature cycling will shorten storage life.
Off white as standard, Green, Yellow, Red Oxide and Black to order.
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 upon
polymerization 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 for any deviation from these values.
