The Sylmasta AB Epoxy Putty Stick is a versatile repair solution designed for maintenance teams who need dependable performance in the field or workshop. Each kit contains multiple 200g epoxy sticks, pre-formatted with the resin and hardener combined into a single, solid unit. This eliminates the need for measuring or mixing separate components, reducing preparation time and minimizing mess. To use, simply cut off the amount required, knead it by hand until the color is uniform, and apply directly to the repair surface.
The putty’s extended working time — up to two hours at 68°F (20°C) — gives users more flexibility during application, especially on large or complex repairs. Once cured, the material forms a hard, durable mass that bonds strongly to metal, concrete, brick, ceramics, most plastics, and wood. It can be drilled, tapped, sanded, painted, or machined without cracking or tearing.
Because it cures underwater and on damp surfaces, the Sylmasta AB Putty Stick is well suited for emergency repairs in challenging conditions, including marine, plumbing, and industrial environments. It’s commonly used for sealing pipes, rebuilding structural elements, filling voids, and making surface repairs to concrete and metal — all with the confidence of consistent, high-strength results.
Key Features
Pre-measured Convenience
Each stick contains pre-proportioned parts A and B for consistent results — no separate mixing required.
Extended Working Time
Up to 2 hours of working time at 68°F (20°C) gives users more flexibility to shape and apply the putty before it begins curing.
Strong Mechanical Properties
Achieves a compressive strength of 11,603 psi (80 MPa) and Shore D hardness of 90 after full cure — suitable for high-stress applications.
Adheres to Most Surfaces
Bonds effectively to metal, wood, brick, concrete, ceramic, most plastics, and more—even on wet surfaces or underwater.
High Chemical and Temperature Resistance
Performs in harsh environments with resistance to acids, fuels, and oils. Service temperature ranges from -4°F to 266°F continuous (-20°C to 130°C) and up to 572°F (300°C) intermittent.
Safe, Non-Shrinking Formula
Solvent-free and VOC-free, with no shrinkage or cracking as it cures. Non-flammable and emits no harmful fumes.
