Surface treatment & Environmental conditions
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.

Frequently Asked Questions
What are the primary performance advantages of this coating?
This product offers super weather and wear resistance, excellent crack resistance, and a long service life. It features a high solid content (90%) with low VOC for environmentally friendly, low-odor application, and cures quickly without requiring specialized equipment.
What is the correct mixing ratio and application method?
The mixing ratio by weight is A (main agent) : B (hardener) = 2 : 1. The recommended construction methods are spray or roll coating.
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, and the actual dry time is 15 hours. The minimum and longest recoating intervals are both 6 hours at this temperature.
What environmental conditions are required for application?
Application should be carried out at temperatures between 10-30℃ and relative humidity below 85%. The substrate surface temperature must be at least 3℃ higher than the dew point. Construction is not recommended if the substrate surface exceeds 40℃ or during rain, snow, or sandstorms.
What are the storage requirements and shelf life for this product?
The product must be stored in a cool, dry, and well-ventilated indoor warehouse. Under these conditions, the storage shelf life is half a year.
What safety and labor protection measures should be followed?
All fire sources are strictly prohibited in the batching and construction areas, and good ventilation must be maintained. In case of skin contact, wash immediately with soapy water. If splashed into the eyes, rinse immediately with plenty of water and seek medical evaluation.
