Dimethylsiloxane Cyclohexane (DMC) Market Uses
Dimethylsiloxane Mixed Cyclic (DMC) is an important silicone intermediate that is widely used in various industrial applications. Some of its major uses are listed below:
Production of silicone rubber, silicone fluids and other polysiloxane products
Dimethylsiloxane Cyclic Mixture (DMC) is the main raw material for the production of silicone rubber and silicone oil. Through further processing, products with high and low temperature resistance and good insulating properties can be obtained. These products have a wide range of applications in industry, healthcare, construction and other fields.
As defoamer
Dimethylsiloxane Mixed Cyclic (DMC) is widely used as an antifoam agent because of its low surface tension, good chemical stability, non-toxicity and other characteristics. It is used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper making and other industries, only need to add a small amount to achieve good defoaming effect.
As mold release agent
Dimethylsiloxane Mixed Cyclic (DMC) is often used as a mold release agent for molding and precision casting of various rubber and plastic products due to its non-adhesion to rubber, plastic, metal and other materials. This not only makes mold release easy, but also ensures that the surface of the product is smooth and clear.
As an insulating, dust-proof, and mold-proof coating
A layer of Dimethylsiloxane Mixed Cyclic (DMC) is dip-coated on the surface of glass and ceramics, and after heat treatment, it can form a semi-permanent waterproof, mold-proof and insulating film. In addition, it can be used to treat insulating devices to improve their insulating properties or optical instruments to prevent mold from developing on parts such as lenses.
As a lubricant
Dimethylsiloxane Cyclic Mixture (DMC) is suitable as a lubricant for rubber and plastic shaft conveyor bearings and gears. It can also be used as a lubricant for rolling friction between steel at high temperatures, or for friction between steel and other metals.
As an additive
Dimethylsiloxane Cyclic Mixture (DMC) can be used as a brightener for paints, adding gloss and water repellency to paints. It also improves the printing quality of inks and the brightness of varnishes2.
In summary, dimethicone mixed cyclic (DMC), as a multifunctional silicone intermediate, has a wide range of applications in several industries. From the production of silicone rubber and silicone fluids to its use as defoamers, mold release agents, insulating coatings, lubricants and additives, its uses are diverse and important. In this study, we propose a simple and easy method to prepare superhydrophobic coatings that can be applied on a large scale: firstly, by utilizing the internal porous structure of MCM-41, its extremely large specific surface area (>900 m2/g) and strong adsorptive properties, low surface energy PDMS was loaded into MCM-41 using a vacuum-negative pressure method, resulting in the production of hydrophobically modified MCM-41 (MCM-41/PDMS); Subsequently, MCM-41/PDMS, epoxy resin, curing agent and diluent were blended to produce the superhydrophobic coating by using the blending method; finally, the coating was sprayed on the substrate surface to form the epoxy/PDMS/MCM-41 superhydrophobic coating by using a simple spraying method. In addition, by adjusting the ratio of MCM-41/PDMS and epoxy resin, the optimal balance of hydrophobicity and adhesion was obtained, and mechanical durability tests such as tape peel resistance and abrasion resistance tests were performed on the superhydrophobic coatings under this formulation.
