PTFE soro ayaresa ma bonding adhesion de akwan titiriw abien di dwuma: ɔhyew a ɛkorɔn melting (wim tebea a ɛkorɔn a ɛko tia, 9.5 MPa ahoɔden ne coupling agent, nanso gyae awuduru mframa) ne sodium-naphthalene etching (5 MPa ntɛm adhesion, teateaa nnɔnhwerew 24-48 mfɛnsere, asiane nwura). Paw gyina nneɛma a atwa yɛn ho ahyia sohwɛ ne bere tenten ne bere tiaa mu adwumayɛ so.

PTFE emulsion su a wɔsɔ hwɛ no fa nsɛnkyerɛnne atitiriw asia ho: nea ɛyɛ den (60±2% wɔ T/FSI biara mu 067-2021), pH (9.0-11.0), nneɛma nketenkete no kɛse kyekyɛ (laser diffraction/DLS), viscosity (12-30 mPa·s wɔ 25°C), sɛnea ɛyɛ den (centrifugal, thermal, freeze-thaw), ne sɛnea ɛte. Saa akwankyerɛ yi ka standard test akwan a wɔfa so yɛ parameter biara ho asɛm.
