1. Types of desiccant used
Chemical desiccant: Some chemical desiccants (such as curing agents) can be added directly to paint to speed up the drying of paint.
Hygroscopic desiccants: Such as silica gel, anhydrous calcium chloride, etc., can absorb moisture in the paint can, thereby accelerating drying.
Oxidizing desiccants: Desiccants containing metal salts (such as manganese tartrate, cobalt tartrate) can catalyze oxidation reactions in paint and accelerate drying.
2. Usage
Add to paint: When using paint, add an appropriate amount of desiccant according to the product instructions, stir well and use.
Place in a paint can: Place a desiccant (such as silica gel desiccant) in the paint can to absorb moisture in the can.
Spray desiccant: Use a desiccant spray directly on the paint surface to accelerate surface drying.
3. Precautions
Control the amount: Excessive use of desiccant may cause cracks, blistering and other problems in the paint coating.
Environmental conditions: When using a desiccant, ensure that the environment is well ventilated to avoid harmful gases from affecting the human body.
Safe operation: Avoid contact between desiccant and eyes. If it splashes into eyes, rinse with clean water immediately and seek medical treatment.
4. Other ways to speed up drying
Increase ventilation: Open doors and windows, use fans or air purifiers to increase ventilation and speed up the drying of paint.
Increase temperature: Use a hair dryer or heater to heat the paint, but be careful to avoid overheating.
Apply thinly and multiple times: Apply thinly and multiple times to speed up the drying of paint.
