Precote 15: Pre-Applied Thread Sealing Coating for Reliable, Immediate Leak Protection
Precote 15 helps seal cylindrical and conical threaded joints with a dry-to-touch coating engineered for consistent assembly, controlled thread friction, and broad industrial use.
What Is Precote 15?
Precote 15 is a dry, elastic thread sealing coating used on assembly components such as screws, studs, plugs, pipe threads, flange head screws, plugs with collars, and rivets. Unlike liquid-applied sealants used at the point of assembly, Precote 15 can be pre-applied to components before installation, helping improve speed, cleanliness, repeatability, and production flow.
Key Benefits
- Immediate sealing performance after assembly
- Dry-to-touch coating for cleaner handling and simplified assembly
- Controlled thread friction values during installation
- Consistent assembly properties for repeatable production outcomes
- Elastic coating with strong adherence to the component surface
- Good thermal and chemical resistance
- Suitable for metallic and non-metallic surfaces
- Non-hazardous product profile
