One component epoxy structural adhesive
ZJ-EP502 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 ⾦ shaped profiles. After curing, it has excellent toughness and ⼒ mechanical strength, such as ⾼ shear strength, T-peel strength and impact peel strength. It can effectively improve the static stiffness and dynamic stiffness of ⾼ structural components and increase durability.
