Note: the above data were measured under good ventilation, typical film thickness and relative humidity ≤75%, for reference only. Actual drying time and the interval before overcoating may be longer or shorter, depending on film thickness, ventilation, humidity, underlying paint, early handling requirements and mechanical strength. Only after the coating is fully cured can it be used in immersed environments, but only for short-term or splash exposure.
above are typical data based on good ventilation, typical film thickness and relativehumidity≤ 75%, just for reference only.
Real drying time base on impact of over coating interval, film thickness, ventilation, humidity,undercoat, ahead of loading and unloading and mechanical requirement etc. Immersiononly allowed after full cure but only for short term or splashing.

Notification;
Must use approved thinner, and overcoat on systemic mid-coats or primers. During paint preparation, contact with water, acid, alkali, alcohol etc. is strictly forbidden. Component B reacts readily with water and alcohols; the packaging drum of the remaining Component B after mixing must be tightly sealed.
During application and drying/curing, the relative humidity must not exceed 80%.
The relative humidity should be no more than 85% when application and curing process.
The appearance will lose gloss, whiten and turn to bad quality once the condensation,sudden temperature drop happened.
Muti coats is needed to achieve enough hiding power with brush and roller application,particular for non-chromatic color pigments like organic yellow, orange etc.
When choosing bright colors such as bright yellow, bright orange etc., the undercoat shouldbe similar or lighter colors to achieve enough hiding power.
