One component epoxy structural adhesive
ZJ-EP504 is a kind of one component heat cured epoxy adhesive with excellent properties. It is suitable for bonding cold rolled steel, galvanized steel, galvanized steel, aluminum magnesium alloy and other kinds of ? shaped profiles. After curing, it has excellent toughness and ? mechanical strength, such as ? shear strength, T-peel strength and impact peel strength, which can effectively improve the static stiffness and dynamic stiffness of ? structural components and increase durability.
Product features
ZJ-EP504 can be used for structural bonding of homogeneous or heterogeneous materials.
