He taputapu whakaputa hauota te kaihanga hauota, i hangaia hoki kia rite ki te hangarau PSA. Ka whakamahia e te kaihanga hauota te tātari ngota waro (CMS) hei ngongo. I te nuinga o te wā ka whakamahia ngā pourewa ngongo e rua i te taha whakarara, ka whakahaerehia aunoa te takirere hau e te PLC ngongo, ka hurihia te ngongo pēhanga me te whakaora i te pēhanga, ka wehea katoatia te hauota me te hāora, kia whiwhi ai i te hauota parakore teitei e hiahiatia ana.
Ko ngā rauemi mata o te tātari ngota waro he kapia phenolic, ka pakaruhia i te tuatahi ka honoa ki te rauemi turanga, kātahi ka whakahohehia ngā pore. Ka wehea e te hangarau PSA te hauota me te hāora mā te kaha van der Waals o te tātari ngota waro, nō reira, ka nui ake te horahanga o te mata, ka ōrite te tohatoha o ngā pore, ā, ka nui ake te maha o ngā pore, ngā pore iti rānei, ka nui ake te kaha mimiti.
