calcium octoates, despite having relatively low humidity stability, are used in combination with magnesium, lead, and cobalt driers to enhance their efficiency, resulting in deep drying of paint films and underlying layers. The advantages of using calcium octoates include imparting a shiny color, providing effective moisturizing and pigment dispersion, and preventing lead darkening in transparent environments. However, it is important to note that calcium octoates are flammable, requiring careful handling and maintenance. These octoates find applications in the paint, resin, ink, and PVC industries.
