Industrial-Strength Surface Preparation
PRIMER-70 is an aggressive industrial-grade primer designed to properly soften and prepare compatible PVC and CPVC pipe and fitting surfaces before the appropriate solvent cement is applied.
Its stronger preparation characteristics make it especially useful for demanding installations where proper penetration and surface softening are important to the solvent-cement joining process.
Schedule 80 & Large Pipe Applications
Spears® specially recommends PRIMER-70 for Schedule 80 piping rated 150 psi and higher as well as large-diameter PVC and CPVC pipe and fittings.
The primer can be used with all types, classes, and schedules of compatible PVC and CPVC, while the correct solvent cement should be selected according to the material, size, schedule, and intended service.
Cold-Weather Applications
PRIMER-70 is also an excellent choice for cold-weather applications where more aggressive surface preparation may be beneficial before PVC or CPVC solvent-cement joining.
Installation temperature, pipe size, material, and environmental conditions should still be considered when determining the proper solvent cement and required cure time for the completed piping system.
Clear & Purple Options
PRIMER-70 is available in clear or purple formulations. Purple provides easy visual recognition of primer application and is the version associated with the U.P. Code listing.
Clear primer can provide a less visible finished appearance where permitted, but local code requirements should always be checked before choosing between clear and purple primer.
Installation & Selection Considerations
- Use with PVC or CPVC.
- Keep the container tightly sealed.
- Confirm local primer color requirements.
- Consider PRIMER-70 for Schedule 80 and large pipe.
- Follow with the appropriate PVC or CPVC solvent cement.
