Hand-mixable two-component epoxy putties formulated for maximum strength, durability, chemical resistance and ease of application. Nine grades — one for every industrial repair scenario. Cures in minutes. Machinable, drillable, tappable, paintable.
PSI's specialty epoxy putty sticks, tapes, bars, industrial pastes and potting compounds offer a wide range of easy-to-use epoxies for industrial maintenance and DIY use. Each grade is formulated to deliver optimum performance in a specific type of application.
Some grades are fast-cure for quick, strong emergency repairs; others are slower-curing for reconstruction, moulding and sculpting. Some carry NSF Standard 61 certification for drinking-water contact. All are user-friendly, low-hazard products for tough, permanent repairs — with excellent resistance to a wide range of chemicals and solvents.
Use for: hydrocarbons, ketones, alcohols, halocarbons, aqueous salt solutions, dilute acids, bases and more. Once cured, every grade can be machined, drilled, tapped, ground, filed or painted.
Choose by substrate and application. All grades mix 1:1 by hand, stick to wet or dry surfaces and are fully cured in under an hour.
Steel-reinforced, hand-mixable, non-rusting epoxy putty. For emergency steel repairs — tanks, pipes, castings, threaded fittings.
Download datasheet →Titanium-filled, highest-strength general-purpose grade. Stronger bonds than Fast Steel for demanding structural repairs.
Download datasheet →Aluminium-filled. Colour-matches aluminium castings and fittings — boats, engine blocks, HVAC, aircraft ground equipment.
Download datasheet →Copper-filled. For copper pipes, roofing, flashings, brass fittings and decorative metalwork.
Download datasheet →Formulated for PVC, ABS, fibreglass and most rigid plastics. Repair tanks, pipes, housings, fenders.
Download datasheet →Wood-colour grade. Repairs rot, cracks and holes in timber. Carves, sands, stains and paints like wood.
Download datasheet →Concrete-grey, cement-filled grade. Plug leaks, patch holes and anchor bolts in concrete, masonry and stone.
Download datasheet →Underwater-curing. Fixes leaks in submerged tanks, pools, pipes and boat hulls without draining.
Download datasheet →Fast-cure general-purpose grade for emergency repairs across mixed substrates. Service-ready in minutes.
Download datasheet →Clean the area. Remove oil, paint and rust. Surface can be dry, wet, or even underwater (grade-dependent).
Cut off the required amount of stick. Knead by hand for ~30 seconds until one uniform colour.
Press firmly into the repair, shape with wet fingers. Use within the working time.
Once cured, machine, drill, tap, sand, file or paint as required.
Cured PSI epoxy putties are highly resistant to corrosion and deterioration by dilute acids and caustics, and withstand exposure to mildly acidic water.
