Ishubhu yokunciphisa ukushisa odongeni olukabili yenziwe nge-polymer yekhwalithi ephezulu (ungqimba lwangaphandle) ene-adhesive encibilikayo eshisayo ( ungqimba lwangaphakathi ) .Ishubhu yokunciphisa ukushisa ivikela umswakama kanye nezindawo ezibolayo, kuyilapho inikeza ukufakwa kukagesi nokuvikelwa komshini. Ngesikhathi sokufakwa, ulwelwesi lwezimboni olunamathelayo kushubhu olushwabene lokushisa luyancibilika futhi lusabalalise endaweni enomugqa okudala isivikelo, umgoqo ongenamanzi. Lapho iphola, ungqimba lwangaphakathi lwakha isendlalelo sokunamathela phakathi kweshubhu nengxenye noma ucingo. Inikeza isivalo esibamba amanzi kanye nokuvikela izixhumi noma izintambo.Izinga lokushisa eliqhubekayo lokusebenza lifanele Minus 55°C kuya ku-125°C. Kukhona nebanga elisezingeni lezempi elinezinga lokushisa eliphakeme lokusebenza elingu-135°C. Kokubili isilinganiso esingu-3:1 kanye no-4:1 sihlehla kahle.
