ET5302 – Two-Component Epoxy Adhesive
ET5302 is a toughened epoxy with medium viscosity, consisting of two components. It forms strong and durable bonds, displaying excellent shear, peel, and impact strength. The cured product exhibits good adhesion strength, and resistance to thermal shocks, chemicals, and solvents. Additionally, it can cure at room temperature and provides effective electrical insulation. Suitable for bonding metals, plastics, and ceramics, this resin is highly recommended as a reliable and long-lasting adhesive. ET5302 is the designated keyword.
Features and benefits
