ZDW1031 Water-borne Epoxy Sealer
A two-component water-borne environmentally friendly epoxy sealer composed of water-borne epoxy resin, water, additives and water-soluble amine curing agent, etc.
High penetration, ensuring good adhesion between the ZINDN series products and the substrate surfaces of most concrete, cement and masonry structures; after treatment with this product, the sealing and the adhesion of the composite coating to the substrate are improved.
For preparing cement or concrete substrates before applying high-performance concrete coatings, providing a surface with anti-penetration, easy cleaning and good adhesion for the subsequent coat.
| Colour | Clear |

| Gloss | |
| Volume Solids | 30±3% |
| Mixed density (kg/L) | 1.0±0.1 |
| Dry film thickness (µm) | Minimum 25 | Typical 40 | Maximum 50 |
| Wet film thickness (µm) | 83 | 133 | 167 |
| Theoretical spreading rate (kg/m²) | 0.083 | 0.133 | 0.166 |
Note: as a penetrating sealer, the final dry film thickness depends on the porosity and penetration of the substrate.
| Practical Spreading Rate | Allowing for a loss factor, the substrate porosity and surface roughness affect the practical spreading rate. |

| VOC content | ≤100g/L |
New concrete substrates shall have been completed for at least 20 days; all substrates shall be free from dirt, and all cracks, joints, protrusions and depressions shall be properly treated before applying this product.
Prior to coating application, concrete surface preparation shall be carried out using dust-free blasting equipment, rotary grinding tools, sandblasting or high-pressure water jetting to achieve suitable surface roughness and remove contaminants; remove all dust and keep the substrate clean and free of standing water.
The substrate temperature must not be below 5 °C and must be at least 3 °C above the air dew point. Temperature and relative humidity must be measured on the substrate near 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. |
