Waterborne Epoxy Intermediate Coat ZDW2051 is a waterborne coating used as an intermediate coat. Used as an intermediate coat for high-performance concrete such as bridges, providing a surface with anti-penetration, easy cleaning and good adhesion for the subsequent coating. A two-component waterborne environmentally friendly epoxy intermediate coat composed of waterborne epoxy resin, water, pigments and fillers, additives and water-soluble amine curing agent. Parameters on this page: volume solids 50 ± 3%, dry film thickness 40/60/80 µm, theoretical spreading rate 0.208 kg/m². Comparable models from the same brand: waterborne epoxy micaceous iron oxide intermediate coat ZD5310, ZDW6500 waterborne epoxy primer, waterborne acrylic intermediate coat ZDW2050.

New concrete substrates must be finished for at least 20 days; all substrates must be free from contamination, and all cracks, joints, protrusions and depressions on the substrate must be correctly treated before applying the product.
Before application, remove all dust and keep the substrate clean and free from standing water.
The substrate temperature shall not be below 5 °C and shall be at least 3 °C above the air dew point, with a relative humidity ≤ 80%. Temperature and relative humidity shall be measured on the substrate close to the work area.
Do not apply outdoors in adverse weather such as rain, fog, snow, strong wind and heavy dust;
| Mixing | This product is supplied as two containers forming one unit. Stir the base thoroughly with a power mixer, add the curing agent in the specified ratio, stir again, and add water as appropriate to adjust to a suitable application viscosity. Once mixed, use within the specified pot life. |
