CAS 115-10-6 in coatings 

The chemical substance with CAS number 115-10-6, i.e. dimethyl ether, has shown a wide range of application potential in many fields due to its excellent miscibility, especially its ability to easily miscible with most polar and non-polar organic solvents, which makes it occupy a pivotal position in the chemical industry. When deeply exploring the common paint ingredients in daily life, it is not difficult to find that dimethyl ether has also quietly become a member of the coating formulation.

Behind the decision to add dimethyl ether to coatings, there are multiple scientific considerations and practical application needs, including the following aspects:

(1) Efficient dissolving resin: Dimethyl ether, as an efficient solvent, can effectively dissolve various types of resins such as acrylic resin, alkyd resin, etc., to ensure that these key components are evenly dispersed in the coating system. This property is essential for improving the flow and dispensability of the coating, ensuring that the coating is applied smoothly over the target surface, resulting in a uniform and dense coating.

(2) Optimize viscosity adjustment: As a diluent, dimethyl ether greatly improves its workability by adjusting the viscosity of the coating. In the spraying operation, adding an appropriate amount of dimethyl ether can make the coating easier to atomize through the spray gun to form fine and uniform droplets, so as to ensure that the coating achieves the ideal coverage effect on the surface of the object, reducing the difficulty and time cost of construction.

(3) Precise control of drying rate: The volatilization rate of dimethyl ether is just right, which can play a key role in the drying process of coating. It not only avoids the problem of solvent residue inside the paint film caused by too fast drying, reduces the generation of paint film defects, but also prevents the drying process from being too slow and slows down the overall construction efficiency, and ensures the dual optimization of coating quality and construction speed.

(4) Significantly improve the leveling performance: Dimethyl ether can also effectively improve the leveling of the coating, and effectively inhibit the occurrence of flow marks and craters by reducing the surface tension difference between the coating and the coated surface. This feature is essential to improve the smoothness and appearance quality of the coating, making the final product more beautiful and durable.

However, it is important to note that while the use of dimethyl ether in coatings brings many benefits, excessive use can be counterproductive. Not only can it affect the stability of the paint liquid, leading to undesirable phenomena such as resin precipitation or delamination, but it can also weaken the chemical resistance of the paint film and reduce the long-term protection of the coating. Therefore, in practice, the addition of dimethyl ether must be precisely adjusted according to the specific coating formulation and application conditions to achieve the best balance of performance.
