InduMar - Model Stop It PSX -Proprietary Epoxy Sealant System
Combines a proprietary epoxy sealant with a durable composite overwrap to accomplish field repair of leaks to systems with operating pressures up to 2500 psi. The STOP IT PSX Repair System derives its high-pressure capabilities from the use of a field-mixed, two-part epoxy primary sealant and a fiberglass/urethane composite overwrap.
STOP IT5 PSX System can be installed by one person with no special tools or hot work, and provides for the completion of in-field repairs and return to service in a total of 4 hours.
Following the cleaning and preparation of the surface, repairs involve the application of a thin film of epoxy sealant from the supplied cartridge gun. Precise mixing is accomplished with the use of a static mixer that is attached to the gun. Once hardened (approximately 1 hr).the sealant is overwrapped with a fiberglass tape impregnated with water-activated polyurethane resins. Systems may be returned to service at pressures up to 2500 psi as soon as 4 hours following the application of the epoxy.
STOP IT® PSX System can be used almost anywhere – including underwater and in chemical and military facilities – to repair chemical, steam, process and water lines.
STOP IT® PSX System Is Ideally Suited For:
- Routine and emergency high-pressure leak repair
- Sealing joints
- Rebuilding thinning wall in high-pressure piping
- Underwater repairs
Flexibility
While STOP IT® PSX Repair System can be used on straight runs of pipe, its conformability makes it especially useful for repairing leaks at bends, crosses, tees, or any other location.

Application
- Once hardened (approximately 1 hr), the sealant is overwrapped with a fiberglass tape impregnated with water-activated polyurethane resins.
- Set Time: Epoxy – 1 hr; Urethane – Tack free in 3 to 5 minutes; for ambient temperatures of 50°F to 80°F (10°C to 27°C).
- Cure Time: 4 hour minimum time. 12 hours for optimum pressure performance. See detailed instructions for breakdown of time.
- Pressure Retention: 2500 psi for leaks less than 0.125” od. 500 psi for voids up to 1.0” od (supporting screen required).
- Temperature/Heat Resistance: From -20°F up to 250°F (-29°C to 121ºC) – continuous. From 250°F to 500°F (121°C to 260°C) – temporary exposures. If possible, the pipe should be at ambient temperature before application.
