why does water based paint go yellow

The yellowing of certain water-based paints, akin to oil-based paints, can be attributed to the presence of alkyd components. Despite being predominantly water-based, these paints incorporate elements of alkyd, which are responsible for the color change over time. Alkyd, a synthetic resin derived from oil, imparts specific properties to the paint, such as improved durability, adhesion, and smoothness of finish. However, it also possesses a tendency to yellow over extended periods. This yellowing effect can occur due to various factors, including exposure to sunlight, heat, or other environmental conditions. Therefore, it is important to consider these factors and select paints specifically formulated to resist yellowing if maintaining a long-lasting white appearance is desired.
