Application
| Surface Preparation | The substrate shall be sound, dry, clean and fully cured. Remove dust, laitance, grease, loose layers, mildew and other contaminants; repair cracks or uneven areas before coating. |
| Application Environment | Apply with application temperature 10-35 deg C; relative humidity <= 85%; mixed two-component material used within its pot life. |
| Application Method | Apply by spray, brush, roller. Use compatible thinner/cleaner such as clean water where permitted where specified. Mix, thin and recoat according to site conditions and the coating system requirements. |
Storage and Delivery
| Safety | Confirm substrate condition, compatibility, mixing ratio and application environment before large-area work. Protect from freezing, rain, contamination and direct exposure before the film is fully dry. Do not use material that has exceeded its pot life or has gelled after mixing. Store sealed in a cool, dry and ventilated place and dispose of waste according to local regulations. |

Product FAQ
Can I request the current TDS and SDS for Water-Based Epoxy Primer for Bridges and Tunnels?
Yes. Contact the Qilu Paints export team with the product name, destination country, substrate, coating system, and application environment to confirm current TDS/SDS, packaging, and export requirements.
How should Water-Based Epoxy Primer for Bridges and Tunnels be selected for an export project?
Confirm substrate preparation, exposure environment, target durability, compatible primer/intermediate/topcoat, destination-market documentation, and dangerous-goods classification before quotation or shipment.
What should be checked before applying Water-Based Epoxy Primer for Bridges and Tunnels?
Check surface cleanliness, surface profile, ambient temperature, substrate temperature, dew point, relative humidity, ventilation, mixing requirements, and recoat interval before application.
How should Water-Based Epoxy Primer for Bridges and Tunnels be mixed and applied?
Stir thoroughly before use. For multi-component products, mix base and curing agent according to the current TDS, observe induction time and pot life, and only thin with the recommended thinner.
How should unopened Water-Based Epoxy Primer for Bridges and Tunnels be stored?
Store in sealed original containers in a cool, dry, ventilated place away from heat, sparks, and direct sunlight. Confirm shelf life and packaging with the current TDS/SDS before shipment.
What safety precautions are required during application?
Use suitable PPE, provide ventilation, keep away from ignition sources, and follow the current SDS for handling, fire protection, first aid, and waste disposal.
