Adhesive Systems Poly Prep Primer

Description

Poly Prep primer is a single-component primer used before cyanoacrylate bonding on difficult low-energy substrates. The available technical sheets describe Poly Prep for polyethylene, polypropylene, PTFE, Delrin, certain elastomers, nylon, and other surfaces that do not bond well without treatment. Chemical Concepts lists this item for flammable-use handling with adequate ventilation.

Poly Prep primer Applications

• Preparing polyethylene and polypropylene before instant adhesive assembly.
• Improving bond response on PTFE, Delrin, nylon, and certain elastomers.
• Small-part production where a brush, wipe, spray, or dip primer step fits the process.
• Repair work where replacing the substrate is harder than improving surface response.
• Bond testing on low-energy plastics before moving into a production run.

Use and Safety Notes

Apply the primer only to clean surfaces and confirm the final adhesive system through testing. One referenced technical sheet says parts may be ready for assembly after a short wait, while the Chemical Concepts page emphasizes flammable handling precautions. Because low-energy plastics vary by grade, mold release, texture, and surface history, test the full primer and adhesive process before approving production.

Keep the primer step consistent from part to part. Small changes in wipe method, dry time, contamination, or adhesive timing can change results on low-energy plastics. For production work, document the substrate grade, cleaner, primer method, adhesive grade, clamp pressure, and cure time so repeat orders can be built from the same process instead of a bench guess.
