VP/VA Copolymers
I-VP/VA Copolymers ikhiqiza amafilimu abonisa ngale, aguquguqukayo, avumela umoya-mpilo ukuthi abambelele engilazini, amapulasitiki nezinsimbi. I-Vinylpyrrolidone/Vinyl acetate (VP/VA) ama-resins aqondile, ama-copolymers angahleliwe akhiqizwa i-polymerization yamahhala yama-monomers ngezilinganiso ezihlukene.Ama-VP/VA Copolymers atholakala njengama-powder amhlophe noma izixazululo ezicacile ku-ethanol namanzi. Ama-copolymers e-VP/VA asetshenziswa kabanzi njengabadali befilimu ngenxa yokuguquguquka kwefilimu, ukunamathela okuhle, ukucwebezela, ukubuyisela amanzi kanye nobulukhuni. Lezi zakhiwo zenza ama-copolymers e-PVP/VA afanele izinhlobonhlobo zezimboni, ukunakekelwa komuntu siqu kanye nemikhiqizo yemithi.
