Recommendations for the use of water-based paint wetting agents
1. Choose the right type of wetting agent
Anionic wetting agents: suitable for occasions where the surface tension of the system needs to be reduced, and help the
wetting and dispersion of pigments and fillers.
Non-ionic wetting agents: have good compatibility and stability, are suitable for a variety of water-based paint systems, and
can effectively improve the leveling and wettability of the paint.
Select according to the paint system: According to the composition, pH value, viscosity and other characteristics of the
water-based paint, choose a wetting agent that matches it to ensure the best effect.
2. Control the amount of addition
Follow the recommended amount: The amount of wetting agent added should strictly follow the product instructions or the
recommendations of the technicians to avoid excessive or insufficient amounts.
Experimentally determine the best amount: In actual applications, the best amount of wetting agent can be determined by
experiment to achieve the best wetting and dispersion effects.
3. Pay attention to the order and method of addition
Addition order: The wetting agent should usually be added before or at the same time as the pigment and filler to ensure that
it can work effectively.
Addition method: The wetting agent should be evenly dispersed in the coating, which can be achieved by stirring, grinding, etc.
Avoid excessive or low local concentration of the wetting agent, which will affect the wetting effect.
4. Pay attention to compatibility and stability
Compatibility: Ensure that the wetting agent has good compatibility with other components in the coating to avoid stratification,
demulsification and other phenomena.
Stability: Select a wetting agent with good stability to ensure the stability of the coating during storage and use.
5. Consider environmental protection and safety
Environmental protection: Give priority to environmentally friendly wetting agents to reduce the impact on the environment.
Safety: Ensure that the wetting agent is non-toxic and harmless, meets relevant safety standards, and ensures safety during
production and use.
6. Actual testing and adjustment
Actual testing: Before formal use, the coating with the wetting agent added should be actually tested to evaluate its wetting,
dispersion, flow and other properties.
Adjustment and optimization: According to the test results, adjust and optimize the type, addition amount or addition method
of the wetting agent to achieve the best effect.
