The "Dainichi Flake Line" is a vinyl resin-based flake material that excels in chemical resistance and is strong against temperature changes and impact. In particular, it demonstrates excellent properties even against chromic acid, nitric acid, chlorine gas, mixed acids of hydrofluoric acid and nitric acid, and concentrated sulfuric acid, which are impossible for rubber. Additionally, it has adhesive strength equal to or greater than that of hard rubber linings and possesses remarkable impact resistance. 【Features】 ■ The construction process is straightforward, ensuring consistent quality without variation due to the lineman's skills. ■ Chemical resistance and heat resistance are superior compared to conventional linings such as PVC and FRP. ■ Completely prevents the permeation of liquids and gases. ■ Has low shrinkage during curing and a small linear expansion coefficient after curing, resulting in very high adhesion. ■ Superior heat stress resistance, abrasion resistance, and impact resistance compared to other lining materials. *For more details, please download the PDF or feel free to contact us.
