Waterproof yog hais txog qhov zoo ntawm cov khoom siv lossis cov khoom uas yog impermeable, lub ntsiab lus nws tsis pub dej hla dhau. Cov khoom tsis muaj dej tuaj yeem ua tiav hauv dej yam tsis muaj dej lossis ua kom cov khoom puas tsuaj. Cov ntaub ntawv tsis muaj dej yog siv rau ntau cov ntawv thov, suav nrog sab nraum zoov, khaub ncaws, khoom siv hluav taws xob thiab cov khoom siv. Cov dej tsis kam yog feem ntau ua tiav los ntawm kev siv cov tshuaj tsis muaj dej tshwj xeeb, cov txheej txheem lossis kev kho mob los tsim kom muaj kev thaiv kom tsis txhob muaj dej los ntawm cov khoom.
Dej tsis kam lees txog qhov muaj peev xwm ntawm cov khoom lossis saum npoo kom tiv taus cov dej ntws mus rau qee yam. Qhov no txhais tau tias dej yuav raug muab rov qab los yog khiav tawm saum npoo ntau dua li tau nqus lossis cov khoom siv. Txawm li cas los xij, cov ntaub ntawv tsis muaj dej tsis yog kiag li, thiab ntev raug rau dej yuav kawg li ntawm lawv. Dej tsis kam yog feem ntau ua tiav los ntawm kev siv cov txheej txheej, kev kho mob, lossis cov ntaub ntawv tshwj xeeb uas tsim cov khoom siv hydrophobic.
Dej reprellency txhais tau tias ib yam khoom tuaj yeem tiv taus dej mus rau qee qhov, tab sis tsis yog impermeable. Nws yuav tiv thaiv cov dej tsis txhob nkag mus rau saum npoo rau ib lub sijhawm luv luv, tab sis nws tseem tuaj yeem ua dej noo yog raug dej ntev. Waterproof, ntawm qhov tod tes, txhais tau tias cov khoom siv tsis tau kiag li thiab tsis pub cov dej tsis txaus ntseeg txawm tias thaum submerged nyob rau hauv dej ntev. Qhov no feem ntau cuam tshuam nrog cov txheej txheem tshwj xeeb lossis membrane uas tsim cov kev tsim ntawm cov khoom thiab cov dej, tiv thaiv ib qho dej los ntawm kev hla dhau.
