Surface treatment
Base surface polishing
Environmental conditions
The coating temperature range is 10-30℃, the relative humidity is below 85%, the surface temperature of the substrate is more than 3℃ higher than the dew point, and the 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 carry out painting construction. Rain, snow, sand and other bad weather, can not be painted.
Packaging specification

Frequently Asked Questions (FAQ)
What is the recommended mixing ratio of this product?
The mixing weight ratio is Component A (main agent) : Component B (hardener) = 2:1. Make sure to mix thoroughly before construction.
What are the environmental requirements for coating construction?
The ideal coating temperature is between 10-30℃, and the relative humidity should be below 85%. Do not paint if the substrate temperature is above 40℃, or during rain, snow, sandstorms, and other severe weather.
How long does it take for the coating to dry at 23℃?
At a substrate temperature of 23℃, the surface drying time is approximately 30 minutes, the actual dry time is 15 hours, and the recoating interval is 6 hours.
How should the product be stored, and what is its shelf life?
The product must be stored in a cool, dry, and well-ventilated indoor warehouse. Its standard storage period is half a year (6 months).
What safety measures should be followed during application?
All fire sources are strictly prohibited at the batching and construction sites, and good ventilation must be maintained. If lacquer splashes on your skin, wash immediately with soapy water. In case of contact with eyes, flush immediately with plenty of water and seek medical attention.
