3. Product Overview and Features
The CRC SP-350 Corrosion Inhibitor is a high-performance lubricant designed for long-term protection of metal components. It forms a protective film that prevents rust and corrosion, particularly in indoor storage environments.
Key Features:
- Superior lubrication and corrosion prevention for metal surfaces.
- Effective for components and assemblies stored indoors.
- Provides protection for up to two years.
- Evaporates slowly, ensuring sustained protection.
- Facilitates easy start-up of stored equipment by preventing rust and providing initial lubrication.
4. Applications
CRC SP-350 is suitable for a variety of indoor applications requiring long-term corrosion protection and lubrication:
- Precision machine surfaces.
- Protective coating for assemblies during storage or transport.
- Stored machinery requiring start-up lubrication.
- General metal components susceptible to rust in indoor environments.
5. Preparation and Application Instructions
5.1 Preparation:
- Ensure the area is well-ventilated.
- Wear appropriate personal protective equipment (PPE), including gloves, eye protection, and face protection.
- Clean the metal surfaces thoroughly to remove any existing rust, dirt, grease, or moisture. A clean, dry surface ensures optimal adhesion and protection.
- Shake the pail gently if there's any indication of separation, though this product is typically stable.
5.2 Application:
CRC SP-350 can be applied by dipping, brushing, or spraying (if transferred to a suitable spray device).
- Dipping: Immerse the component completely into the SP-350 liquid. Allow excess to drip off.
- Brushing: Apply an even coat to the metal surface using a brush. Ensure full coverage.
- Spraying: If using a spray device, apply a uniform, thin film over the entire surface. Avoid over-application.
- Allow the product to dry or set as needed. The slow evaporation rate ensures a lasting protective film.
6. Storage and Disposal
6.1 Storage:
- Store in a cool, well-ventilated area.
- Keep container tightly closed when not in use.
- Keep away from heat, sparks, open flames, and other ignition sources.
- Store locked up, out of reach of children and unauthorized personnel.
6.2 Disposal:
Dispose of contents and container in accordance with all applicable local, regional, national, and international regulations. Consult local authorities for proper disposal methods for hazardous waste.

8. Troubleshooting
As a corrosion inhibitor and lubricant, troubleshooting typically involves ensuring proper application and storage. If issues arise, consider the following:
- Inadequate Protection: Ensure surfaces were clean and dry before application. Verify that a sufficient, even film was applied. Reapply if necessary.
- Product Separation: While uncommon, if the product appears separated, gently stir or agitate the pail to ensure homogeneity before use.
- Application Difficulties: If brushing or dipping is difficult due to viscosity, ensure the product is stored at recommended temperatures. Do not dilute unless specified by the manufacturer.
