Frequently Asked Questions (FAQ)
Q 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 wide range of substrates.
Q What is the mixing ratio of Component A to Component B?
The weight mixing ratio is A : B = 15 : 1. After mixing, allow 5 minutes before beginning construction to ensure proper activation.
Q How long does the product take to fully cure?
The surface drying time is approximately 2 hours. Full (real) drying is achieved within 24 hours under standard conditions (15–25℃).
Q What are the recommended storage conditions and shelf life?
The product should be stored in a cool, dry, and well-ventilated indoor warehouse. The shelf life is half a year from the date of manufacture.
Q What weather conditions are required for application?
Application should be carried out at temperatures between 5–35℃ with relative humidity below 80%. Avoid painting during rain, snow, wind, or sandstorm conditions. Do not apply when the substrate surface temperature exceeds 40℃.
Q What safety precautions should be taken during application?
All ignition sources must be eliminated at the construction site. Workers must wear appropriate protective equipment to prevent inhalation of paint mist and contact with skin or eyes. In case of skin contact, wash immediately with soap and water. If the product enters the eyes, rinse thoroughly with clean water and consult a doctor.
