Silicone oil is a versatile additive in coatings, valued for its low surface tension and excellent lubricating properties. By reducing surface defects such as brush marks, craters, and orange peel, silicone oil significantly improves leveling and provides a smooth, glossy finish. Even at low dosages, it helps coatings spread evenly, ensuring a uniform film.
Another key benefit is its defoaming capability. During mixing, spraying, or rolling, bubbles often form and affect film appearance and density. Silicone oil rapidly spreads on the liquid surface, lowering local surface tension and accelerating bubble rupture. This results in denser, clearer, and more attractive coatings.
With the rise of environmentally friendly technologies, silicone oil has also been adapted for waterborne coatings, combining eco-safety with functional performance. This dual role highlights its increasing value in modern coating formulations.
