Proven track record in Shinkansen applications! Water-soluble vibration-damping paint that significantly reduces noise. Suitable for thin and thick coatings, curved surfaces, uneven surfaces, and large area applications.
CCAI's "Dai-Porgi DP" is a vibration-damping material in the form of a water-based paint that does not contain environmentally harmful organic solvents. It reduces unpleasant noise from steel plates and other sources to a softer sound. Being a paint type, it can be applied to curved surfaces and complex shapes, allowing for flexible adjustments between thin and thick applications, making it suitable for large area applications. Additionally, it demonstrates excellent vibration-damping performance across a wide temperature range. 【Features】 ■ High vibration-damping performance across a wide frequency range ■ Flexible application of thin and thick coatings (suitable for curved and uneven surfaces) ■ Free application methods tailored to the shape (brush or spray) ■ One-component water-based paint that does not contain organic solvents, ensuring safety and environmental consideration ■ A non-combustible type is also available for railway vehicle material combustion tests. 【Applications】 ・Railways (Shinkansen) ・Automobiles (fenders, floor panels, doors, roof panels, wheelhouses) ・Various facilities including residential buildings *For more details, please refer to the catalog or feel free to contact us.
