⚡ At a Glance
- • Adhesion Strength: Strong bond across metal, ceramics, plastic, wood, tile and concrete; waterproof and wear resistant
- • Best for: Sealing leaks, filling holes and repairing chips in pools, pipes and household fixtures
- • Not ideal for: Applications that demand ongoing flexibility, where a rigid repair could crack
Two-part black epoxy putty sticks seal and fill both underwater and above-water repairs. Cures to a hard, non-shrinking finish that can be drilled, polished and painted.
Watertight Repairs, - thanks to two-part epoxy formulation
A mix-then-apply putty chemically cures underwater and above water, forming a waterproof bond. Moulding time is around 30 minutes and the material fully cures after 24 hours.
Seals leaks in pipes, tanks and pools effectively, allowing submerged repairs without drying out the area first.
Durable Mechanical Strength, - with wear-resistant, impact-tolerant filler
Formulation resists wear, impact and a wide temperature range from -50°C to 130°C, and the cured material does not shrink. Hardened putty accepts drilling and polishing for finishing.
Creates long-lasting patches that withstand temperature swings and mechanical stress, suitable for domestic and industrial fixes.
Easy Sculpting and Finishing, - thanks to 30 minute moulding time and good plasticity
Putty remains workable for about 30 minutes, allowing shaping and modelling before it starts to harden. After 24 hours the surface accepts paint and machining.
Allows neat, shaped repairs and tidy cosmetic finishing, making repairs both functional and presentable.
