The product, Factory Supply Cobalt Octoate CAS 136 - 52 - 7 With Best Price, is a high - quality chemical compound. The Chemical Abstracts Service (CAS) number, 136 - 52 - 7, ensures its unique identification in the chemical industry. Cobalt octoate is also known as cobalt 2 - ethylhexanoate. It usually appears as a dark purple or blue - black liquid, with a characteristic odor.
In terms of basic parameters, it has a certain density and viscosity. The density of cobalt octoate may vary depending on its concentration and production process, typically in the range of 0.9 - 1.1 g/cm³. Its solubility is an important characteristic. It is soluble in most organic solvents such as toluene, xylene, and mineral spirits, but insoluble in water. This solubility property makes it suitable for various applications in organic systems.
One of the main uses of cobalt octoate is as a drying agent in the paint and coating industry. In oil - based paints, it can accelerate the drying process of the paint film by promoting the oxidation and polymerization of unsaturated oils. This leads to a faster - drying paint, reducing the waiting time for the next coat application and increasing production efficiency.
It is also widely used in the rubber industry. Cobalt octoate can be used as a promoter in the vulcanization process. It helps to improve the cross - linking of rubber molecules, enhancing the mechanical properties of the rubber such as tensile strength, tear resistance, and abrasion resistance. In addition, it can also improve the adhesion between rubber and other materials, such as metal cords in radial tires.
In the polyester resin industry, cobalt octoate is used as a catalyst. It can speed up the curing reaction of polyester resins, which is crucial for the production of fiberglass - reinforced plastics, synthetic marble, and other polyester - based products.
When using cobalt octoate as a drying agent in paints, it should be added to the paint formulation at the appropriate stage. Usually, it is added during the mixing process of the paint components. The dosage depends on the type of paint, the drying requirements, and the environmental conditions. Generally, the dosage ranges from 0.1% to 1% by weight of the total paint formulation. It is important to mix it evenly to ensure uniform drying of the paint film.
In the rubber industry, cobalt octoate is added during the rubber compounding process. It is typically added together with other additives such as sulfur and accelerators. The amount used is carefully controlled according to the specific rubber recipe and the desired properties of the final rubber product. Over - dosage may lead to some adverse effects such as reduced aging resistance.
For use in polyester resins, it is mixed with the resin and other curing agents. The addition sequence and mixing time are important factors. Usually, it is added after the resin has been properly mixed with other components, and then the mixture is stirred for a certain period to ensure complete dispersion.
Case 1: A paint manufacturing company was facing long drying times for its oil - based paints, which affected the production cycle. After adding 0.5% cobalt octoate to its paint formulation, the drying time of the paint was reduced from 24 hours to 12 hours. This not only increased the production capacity but also improved customer satisfaction as the delivery time was shortened.
Case 2: A tire manufacturing plant was experiencing problems with the adhesion between the rubber and the steel cords in radial tires. By adding an appropriate amount of cobalt octoate in the rubber compound, the adhesion strength was significantly improved. This led to a reduction in tire delamination failures, improving the overall quality and safety of the tires.
Case 3: A polyester resin production factory wanted to increase the curing speed of its products. After adding cobalt octoate as a catalyst, the curing time of the polyester resin was reduced by 30%. This allowed the factory to increase its production volume and reduce energy consumption during the curing process.
