2-Methyl-2-octadecyl acrylate feem ntau yog siv rau hauv cov kua mem, cov tshuaj pleev xim, cov nplaum, cov tshuaj zas xim thiab cov khoom siv ua tiav, cov khoom siv tawv, cov tshuaj tiv thaiv dej thiab roj, cov tshuaj tiv thaiv kev ntws, cov roj nplua nyeem ntxiv thiab cov roj nyoos viscosity txo qis. Kev tsim cov tshuaj. Nws tuaj yeem npaj thiab tsim [2-methyl-2-octadecyl acrylate-maleic anhydride copolymer, uas tuaj yeem siv los ua cov tshuaj depressant kom txo qhov khov ntawm cov roj nyoos; nws kuj tseem siv tau rau kev hloov kho qhov chaw ntawm cov ntaub txhob lo lo ntxhuav kom zoo dua. Nws muaj cov khoom hydrophobic; ntxiv rau, nws kuj tseem siv tau ua cov khoom siv raw los npaj cov khoom hloov pauv theem rau kev tsim cov ntawv tiv thaiv kub taub hau.

Hauv kev tshawb fawb txog cov ntaub ntawv, 2-methyl-2-octadecyl acrylate yog siv dav vim nws cov khoom zoo heev thiab kev ruaj khov ntawm tshuaj lom neeg. Ua ib qho khoom siv roj nplua nyeem zoo, nws tuaj yeem txhim kho kev ua haujlwm zoo thiab kev ruaj khov ntawm cov khoom siv kho tshuab; tib lub sijhawm, ua ib qho kev hloov kho rau cov txheej thiab cov kua mem, nws tuaj yeem txhim kho kev tiv thaiv huab cua, kev hnav tsis kam thiab kev nplaum ntawm cov khoom, ua rau cov khoom ruaj khov dua thiab zoo nkauj dua.

Hauv kev lag luam tshuaj zoo, 2-methyl-2-octadecyl acrylate ua haujlwm ua tus ua ntej ntawm surfactants thiab tuaj yeem ua tiav ntxiv rau hauv cov tshuaj ntxuav, emulsifiers thiab lwm yam khoom nrog cov haujlwm tshwj xeeb; hauv kev lag luam luam ntawv thiab dyeing, nws kuj tseem siv tau ua softener, antistatic tus neeg sawv cev thiab lwm yam additives, nws tuaj yeem txhim kho qhov kev xav thiab hnav xis nyob ntawm cov ntaub.
