Storage
⚠ This product should be stored in a cool, dry, ventilated indoor warehouse. Storage period: half a year.
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 the eyes and skin. If base coating splashes on the skin, immediately clean with soapy water. If it splashes into the eyes, immediately wash with a large amount of water, then 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.
⛔
Rain, snow, wind, sand and other severe weather conditions — painting is not permitted.
Operation Methods & Requirements
The substrate needs to be polished, with no dust and oil pollution.
Construction Instructions
- Apply to PVC, Polyurea, Silicon PU
- Construction Method Traditional spraying, rolling coating
- Mixing Ratio (Weight) A : B = 15 : 1 — Construction after 5 minutes of mixing
Frequently Asked Questions (FAQ)
Q What surfaces is this product compatible with?
This product is suitable for PVC, Silicon PU, and Polyurea base surfaces, providing excellent strength and adhesion across all these substrates.
Q What is the mixing ratio of Component A to Component B?
The recommended mixing ratio by weight is A:B = 15:1. After mixing, wait 5 minutes before beginning construction to ensure proper activation.
Q How long does it take for the coating to fully dry?
The surface drying time is approximately 2 hours. Full (real) drying is achieved after 24 hours under standard conditions.
Q What are the recommended construction temperature and humidity conditions?
Coating should be applied within a temperature range of 5–35℃ and relative humidity below 80%. Do not apply when the substrate surface temperature exceeds 40℃, or during rain, snow, wind, or sandstorm conditions.
Q How should this product be stored, and what is its shelf life?
Store in a cool, dry, and well-ventilated indoor warehouse. The shelf life is half a year (6 months) from the date of manufacture under proper storage conditions.
Q What safety precautions should be taken during application?
All fire sources must be prohibited at the construction site. Workers must wear appropriate protective equipment to avoid inhaling paint mist or contact with skin and eyes. If contact occurs, rinse with soapy water (skin) or large amounts of clean water (eyes) and seek medical attention immediately.
