Storage
⚠️
This product should be stored in a cool, dry, ventilated indoor warehouse. Storage period: 6 months.
Safety: Prohibit all fire sources at coating and construction sites, and maintain good ventilation. Construction personnel must wear protective equipment to prevent inhalation of paint mist and damage to eyes and skin. If base coating splashes on skin, immediately clean with soapy water. If it splashes into the eyes, immediately wash with plenty of water and seek medical attention.

Construction Conditions
- Coating temperature range: 5–35℃, relative humidity below 80%. Temperature and humidity should be measured near the substrate.
- When the surface temperature of the substrate is higher than 40℃, it is recommended not to proceed with painting.
- Do not paint during rain, snow, wind, sandstorm, or other severe weather conditions.
Operation Methods and Requirements
The substrate needs to be polished — free of dust and oil contamination.

Frequently Asked Questions
What surfaces is this product compatible with?
This product is suitable for PVC, silicon PU, polyurea, and other base surfaces, providing excellent strength and adhesion across a variety of substrates.
What is the correct mixing ratio for Components A and B?
The recommended mixing ratio by weight is A:B = 15:1. After thorough mixing, allow 5 minutes before beginning construction to ensure proper activation.
How long does it take for the coating to fully dry?
The surface drying time is approximately 2 hours. Full cure (real dry) is achieved after 24 hours under standard conditions (substrate temperature 15–25℃).
What environmental conditions are required for application?
Coating should be applied at temperatures between 5–35℃ with relative humidity below 80%. Avoid application when the substrate surface exceeds 40℃, or during rain, snow, wind, or sandstorm conditions.
Is this product safe and environmentally friendly?
Yes. This product contains no solvents, produces no pollution, and is non-toxic. However, construction personnel should still wear appropriate protective equipment to prevent inhalation of paint mist and contact with skin or eyes.
How should this product be stored and what is its shelf life?
Store in a cool, dry, well-ventilated indoor warehouse away from all fire sources. The shelf life is 6 months from the date of manufacture when stored under recommended conditions.
