Lockfast Steel Epoxy Stick is a hand-mixable, steel-reinforced, non-rusting epoxy putty used to provide fast, permanent repairs to items made of ferrous metal. It will repair holes, cracks and threads in castings, pipes and tools, and can be used to hold fixtures and signs, to make models and prototypes, to form nuts in situ and to lock threads. When mixed it sets to a hard, dark grey material which can be drilled, tapped, machined or filed as required.
Typical uses include repairs to leaking iron pipes and tanks; to rebuild stripped threads; fill blowholes, cracks and voids in metal; for moulds, patterns and castings; and to repair rust-damaged equipment bodies, metal gutters, downspouts, and duct work. Lockfast Steel Stick can also be used to create prototype parts, form custom tools and handles, fabricate missing machine parts, and anchor machines.
To ensure a good bond, sand both surfaces and ensure they are dry, free of grease, dirt, paint etc.
Twist or cut off the required amount of product, knead the putty with the fingers until uniform colour is achieved.
Press the putty onto the prepared surface within 2 minutes of mixing.
For a smooth appearance, rub with water or a damp cloth within the working life of the putty.
After 5-10 minutes the epoxy putty will harden like metal and start to form a bond. After 60 minutes the material will be cured sufficiently for practical use.
