Frequently Asked Questions
Q
What surfaces is this coating compatible with?
This coating is suitable for PVC, silicon PU, polyurea, and other base surfaces, providing excellent strength and adhesion performance across these substrates.
Q
What is the recommended mixing ratio for components A and B?
The recommended weight mixing ratio is A:B = 15:1. After mixing, wait 5 minutes before beginning construction to allow proper induction time.
Q
How long does the coating take to fully cure?
The surface drying time is approximately 2 hours. Full (real) drying takes 24 hours under standard conditions (substrate temperature 15–25℃).
Q
What are the ideal environmental conditions for application?
The coating should be applied when the temperature is between 5–35℃ and relative humidity is below 80%. Avoid application when the substrate surface temperature exceeds 40℃, or during rain, snow, wind, or sandstorm conditions.
Q
Is this product safe to use indoors? Does it contain solvents?
Yes, this product is solvent-free, non-polluting, and non-toxic. However, proper ventilation must be maintained during application, and workers should wear appropriate protective equipment to prevent inhalation of paint mist or contact with skin and eyes.
Q
What is the shelf life and how should the product be stored?
The product has a shelf life of six months. It should be stored in a cool, dry, and well-ventilated indoor warehouse, away from all fire sources and direct sunlight.
