If the storage period exceeds, inspection can be carried out according to the items specified in this product standard. If it meets the technical requirements, it can still be used. Please use it as soon as possible after opening, and it must be resealed and stored when not in use. This product does not contain organic solvents and can be transported as a non hazardous material. During transportation, rain and sunlight should be strictly prohibited to avoid severe collisions. Materials should be neatly and stably stacked, and should comply with relevant regulations of the transportation department.

Base surface requirements: The concrete base surface should be cleaned, repaired flat, and polished to a certain roughness. Ensure that the concrete curing is completed, the strength reaches C25 or above, and the moisture content is less than 8%. After processing the base surface, the next process should be carried out as soon as possible. Environmental temperature and humidity requirements: The construction environment temperature should be between 5~35 ℃, and the base surface temperature should be at least 5 ℃ higher than the air dew point temperature; The humidity range should be between 30% and 80%. Ventilation conditions: Ventilation should be maintained during construction, but construction should not be carried out when there is strong wind.

• What is the solid content of this polyurea product?
  This polyurea product has a solid content of 100%, meaning it contains no solvents and delivers full material performance upon application.
• What are the main application areas for this product?
  This product is suitable for high-hardness applications including pickup lining, mine wear mechanical lining, and wear deck surfaces in demanding industrial environments.
• What are the recommended construction environment conditions?
  Construction should be carried out at an ambient temperature between 5°C and 35°C, with relative humidity between 30% and 80%. The base surface temperature must be at least 5°C above the air dew point. Avoid construction in strong wind conditions.
• How should this product be stored, and what is its shelf life?
  The product should be stored in a cool, dry, and well-ventilated indoor warehouse, away from sunlight, rain, and ignition sources. The shelf life is 6 months from the production date under original packaging and specified storage conditions. Products exceeding this period may still be used if they pass re-inspection.
• How much product is needed per square meter for waterproofing?
  The recommended usage is 1.2 kg/mm/m². For the standard waterproof thickness of 1.5mm, approximately 1.8 kg per square meter is required.
• Is this product resistant to chemicals such as acids and alkalis?
  Yes. Test results confirm no change after immersion in 20% NaOH solution for 7 days (alkaline resistance) and no change after immersion in 10% HCL solution for 7 days (acid resistance), demonstrating excellent chemical resistance performance.
