PH adjustment of water-based paint-Ask water character paint expert
Question: If the pH value of the water-based paint is not weakly alkaline or the pH value is unstable, what effect will it have in actual use? Thank you!
Response:
The unstable pH of water-based paints has two main effects on water-based paints.One is that it affects the stability of the filler or paste in the resin because the pH of the system affects the surface chemistry of the particles and affects the dispersibility or degree of bonding of the particles. In severe cases, it will cause gel or bean curd.Second, it will affect the role of the system and the substrate.For example, for waterborne wood lacquers, some woods will exhibit different colors due to the pH of the coating. Alternatively, for aqueous anti-corrosive paints, the pH on the corrosive metal surface greatly affects the corrosion resistance of the water-resistant anti-rust paint .
