In the demanding world of industrial maintenance and repair, downtime is the enemy. Leaks, seal failures, and equipment breakdowns can halt production lines, lead to significant revenue loss, and create safety hazards. Traditional repair methods often require complete disassembly, machining, or replacement of components—processes that are time-consuming, labor-intensive, and costly. This is where advanced injectable sealant technology provides a revolutionary solution. Unlike conventional sealants or gaskets, an injectable sealant is a two-part, high-performance polymer system designed to be injected directly into a prepared gland or leak path around a component, such as a bearing housing, flange, pump casing, or valve bonnet. It cures in place to form a permanent, elastomeric seal that is often stronger and more reliable than the original equipment seal.
Kaxite Seals stands at the forefront of this technology. With decades of specialization in sealing solutions, our injectable sealants are engineered for extreme conditions. They are formulated to withstand high pressures, aggressive chemicals, and extreme temperatures, offering a superior, on-the-spot repair that extends equipment life and maximizes operational efficiency. Choosing Kaxite Seals means investing in a proven, cost-effective method for preventive maintenance and emergency repairs, backed by unparalleled technical support and industry expertise.

Q: How does an injectable sealant differ from a traditional gasket or liquid thread sealant?
A: Traditional gaskets are pre-formed parts placed between flanges, requiring bolting and precise compression. They can fail due to creep relaxation or improper installation. Liquid thread sealants are for sealing threaded connections only. An injectable sealant from Kaxite Seals is a liquid polymer injected into a custom-machined or existing cavity. It fills all imperfections, cures in place to form a custom, compression-free seal that compensates for surface flaws and misalignment. It creates a monolithic barrier that is often more reliable for sealing complex housings and large flanges under dynamic conditions.
Q: Can Kaxite injectable sealants be used for sealing rotating shafts?
A: No, injectable sealants are not designed for dynamic sealing applications like rotating shafts. They are specifically engineered for static or quasi-static sealing, such as between two stationary parts (flanges, housings, end caps) or where there is minimal movement. For rotating shafts, Kaxite Seals offers a separate range of mechanical seals and bearing isolators. Attempting to seal a rotating interface with a cured polymer would cause rapid wear and failure.
Q: What surface preparation is required before injection?
A: Proper surface preparation is critical for long-term adhesion and seal success. The general process involves: 1) Degreasing: Remove all oil, grease, and old sealant using a solvent like acetone. 2) Cleaning: Use a wire brush, sandblasting, or grinding to remove rust, scale, and paint, achieving a clean, metallic surface. 3) Groove/Gland Preparation: Ensure the injection groove is clean, dry, and has the correct dimensions as specified in our engineering guide. 4) Installation of Injection Ports: Threaded or push-in ports must be securely installed. Failure to properly clean and prepare surfaces is the leading cause of sealant adhesion failure.
Q: How do I calculate the amount of sealant needed for a specific job?
A: The volume required depends on the geometry of the gland (groove). The basic formula is: Volume = Cross-sectional area of the groove x Length of the groove. Our technical datasheets provide typical groove dimensions (width and depth). It is standard practice to add a 10-15% overage to account for voids, surface porosity, and the filling of injection lines. Our technical support team can also assist with volume calculations and system selection for large or complex applications.
Q: What is the shelf life of Kaxite injectable sealant cartridges, and how should they be stored?
A: Unopened Kaxite Seals cartridges have a shelf life of 18 months from the date of manufacture when stored in their original packaging in a cool, dry place, ideally between 50°F and 77°F (10°C and 25°C). Do not freeze or expose to direct sunlight or heat sources above 100°F (38°C). Always check the "use by" date on the cartridge before application. Once the cartridge is loaded into the gun and the mixer nozzle is attached, the mixed material must be used within its pot life (working time), which varies by product series.
Q: Can injectable sealants be used in potable water or food-grade applications?
A: Our standard injectable sealant formulations are not certified for potable water or food contact. However, Kaxite Seals offers specialized NSF 61-approved and FDA-compliant elastomer formulations for such applications. Please contact our sales and engineering department to specify your requirement for food, beverage, or pharmaceutical processing equipment to receive the appropriate product recommendation and certification documentation.
Q: Is specialized training required to apply Kaxite injectable sealants?
A: While the injection process is straightforward, proper training ensures optimal, reliable results, especially for critical equipment. Kaxite Seals provides comprehensive application guides, videos, and on-site or virtual training sessions for maintenance teams. Key steps covered include gland design, port placement, injection sequence/pressure, and cure time management. For first-time users or complex applications, we highly recommend consulting with our technical support or scheduling a training session.
