Calcium octoate acts as an auxiliary dryer and is considered one of the important auxiliary dryers. It has relatively low humidity stability and is used in combination with magnesium, lead, and cobalt driers because it enhances the drying of the paint film, penetrating deeply and promoting the drying of underlying layers of paint.
The advantages of this drier include making the color shiny, providing good moisturization and dispersion for the pigment, and preventing lead darkening in transparent environments. It is important to note that calcium octoate is flammable, so proper care should be taken in its maintenance. This compound is commonly used in the paint and resin industries, as well as in ink and PVC applications.
· Paints and Coatings: Calcium octoate is used as a paint dryer, accelerating the drying process of oil-based paints, varnishes, and coatings.
· Resins: Calcium octoate serves as an auxiliary dryer in resin systems, promoting faster drying and curing for high-quality resin products.
· Inks: Calcium octoate aids in the quick drying of ink formulations, enabling faster printing processes and improved adhesion on various substrates.
· PVC Stabilization: Calcium octoate acts as a heat stabilizer in PVC formulations, preventing degradation during processing and heat exposure, ensuring thermal stability in PVC-based products.
Application and dosage of calcium octoate vary based on formulation requirements. Manufacturers determine optimal usage levels and combinations of additives for desired drying characteristics.
