Do you know about silicone? It is a polysiloxane (silicone resin) composed of silicon-oxygen bonds (-Si-O-Si-) as the backbone, belonging to semi-organic and semi-inorganic polymer compounds with significant industrial value. Silicon-containing polymers can be categorized into four main types: silicone oil, silicone rubber, silicone resin, and silane coupling agents. Silicone oil, primarily used as a coating additive, stands as one of the most effective defoaming agents in coatings. Additionally, it enhances the leveling properties of coatings and prevents the occurrence of flow marks.

The addition ratio of silicone oil emulsion in water-based coatings is generally between 5% and 10%. This ratio aids in enhancing the physical and surface properties of the coating, such as improving lubricity, anti-adhesion, and glossiness. However, it is important to note that excessive addition can impact the drying speed and adhesion of the coating. The Role and Addition Ratio of Silicone Oil Emulsion Silicone oil emulsion, as a common paint additive, plays a significant role in waterborne coatings. It possesses excellent lubricity and anti-adhesion properties, effectively reducing the surface tension of the coating, thus making it easier to apply and cover. Additionally, silicone oil emulsion enhances the gloss and surface smoothness of the coating, resulting in a smoother and more delicate coating surface. It is generally recommended to maintain the addition ratio of silicone oil emulsion between 5% and 10%. This proportion has been established through numerous experiments and practical verification, ensuring that the silicone oil emulsion can fully leverage its performance benefits in the coating while avoiding any adverse effects.

The Influence of Addition Ratio on Coating Performance The proportion of silicone oil emulsion added significantly impacts the performance of the coating. An appropriate amount of silicone oil emulsion can enhance the lubricity and anti-sticking properties of the coating, improve application efficiency, and impart better gloss and smoothness to the coating. However, if the amount added is excessive, it may slow down the drying speed of the coating, and even lead to issues such as incomplete drying and stickiness, seriously affecting the quality and lifespan of the coating. Therefore, in practical applications, we must comprehensively consider the proportion of silicone oil emulsion based on factors such as the type, usage, and application conditions of the coating. Through continuous adjustment and optimization, we aim to find the most suitable amount to ensure optimal coating performance. Conclusion and Outlook In summary, the proportion of silicone oil emulsion added to water-based coatings is a matter that requires careful consideration. By adding silicone oil emulsion appropriately, we can significantly enhance the physical and surface properties of water-based coatings, improving their water resistance, abrasion resistance, and gloss. However, it is also crucial to carefully control the amount added to avoid adverse effects on the coating. Looking ahead, with the continuous advancement of technology and the research and development of new coating additives, we believe that the application of silicone oil emulsion in water-based coatings will become more widespread and profound.
