Hydrated Lime plays a significant role in the paint industry by acting as a filler and pH regulator in various paint formulations. Its fine particle size allows it to blend smoothly with other ingredients, improving the viscosity and application properties of the paint. Hydrated Lime also enhances the durability and weather resistance of paints, making them more suitable for outdoor applications. Additionally, it contributes to the opacity and brightness of the final paint finish, ensuring better coverage and a more aesthetically appealing result.
