International Ceilcote 680M

International Ceilcote 680M Primer/Saturant is a low viscosity, 85% volume solids epoxy compound, based on a unique adduct curing technology. Applied in one or two coats over correctly prepared surfaces, it provides a moisture resistant barrier and improves the surface strength of concrete. 

Best Uses

Ceilcote 680M is recommended for use as a primer for steel and as a concrete sealer where non-dusting and/or mild chemical resistance is required.  It is also suitable for use as a blast holding primer. The addition of Ceilcote C#1 Powder provides conductivity where required.

Application

Recommended application is by Airless Spray, Brush or Short nap roller. Air Spray (Conventional) is not recommended with this product.

All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application, all steel surfaces should be assessed and treated in accordance with ISO 8504:2000. Oil or grease should be removed in accordance with SSPC-SP1 Solvent Cleaning.

Steel Substrates
For immersion service or service in humid conditions or elevated temperatures, this product should be applied to surfaces which have been prepared by abrasive blast cleaning to Sa3 (ISO 8501-1:2007), SSPC SP5 or NACE #1. For dry environments, abrasive blast cleaning to Sa2½ (ISO8501-1:2007), SSPC SP10 or NACE #2 will be suitable. A minimum surface profile of 75 microns (3 mils) is required.

International Ceilcote 680M must be applied before oxidation of the steel occurs. If oxidation does occur, the entire oxidised area should be re-blasted to the standard specified above. Any surface defects that are revealed by the blast cleaning process should be ground, filled or treated in the appropriate manner.

Concrete Substrates
Concrete should be well cured prior to priming with Ceilcote 680M. The concrete surface should be dry and pass the plastic sheet test (ASTM D4263). All surfaces should be clean, dry and free from curing compounds, release agents, trowelling compounds, surface hardeners, efflorescence, grease, oil, dirt, old coatings and loose or disintegrating concrete. All concrete surfaces must also be abrasive blast cleaned to provide a roughened surface and remove laitance. The surface tensile
strength (ASTM 4541) as prepared should be at least 2MPa (300 psi).
