1. Silane Nkitahodi Agent Bonding Layer

Fiberglass a wɔansiesie no ntumi ne PTFE resin nkɔ tẽẽ. Enti, ɛsɛ sɛ wɔde silane coupling agents sesa fiberglass ntama wɔ ne yɛ mu. Ade a ɛka bom no ano biako ne silanol akuw (Si-OH) a ɛwɔ fiberglass no ani no yɛ adwuma wɔ nnuru mu, bere a awiei foforo no kura akuw a ɛyɛ nnam a ɛne fluororesins wɔ abusuabɔ kɛse anaasɛ ɛyɛ adwuma. Ɛsom sɛ nnuru bonding bridge a ɛda fiberglass nnompe ne PTFE coating ntam, saa layer yi ma titiriw nnuru anchorage ma ne nyinaa structural lamination.

2. Hot-Melt Adhesive Mfinimfini Fam

Wɔ cross-section hwɛ a ɛkorɔn PTFE ntama a ɛyɛ hyew kɛse mu no, wobetumi ahu gradient transition layer a PFA (Perfluoroalkoxy alkane) anaa FEP (Fluorinated Ethylene Propylene) wom pefee wɔ PTFE coating ne fiberglass substrate ntam.
