Procure PC77 Cyanoacrylate Primer enables the adhesion of difficult to bond substrates such as low energy plastics (polypropylene, polyethylene, silicon rubber and even PTFE). PC77 works by increasing the surface energy of the substrate to which it is applied, allowing Procure cyanoacrylates to bond the surfaces.
1. Brush primer onto surfaces to be bonded.
2. Wait for the solvent carrier to evaporate (normally 10-30 seconds).
3. Apply appropriate Procure cyanoacrylate to one of the surfaces and assemble parts.
If the bond is Polypropylene to polypropylene, both surfaces should be primed.
For information on safe handling of Procure PC77 Cyanoacrylate Primer consult the Safety Data Sheet (SDS).
