Acrylic xim feem ntau yog dej raws, nws yuav siv tau raws li lub facade thiab raws li ib tug sab hauv. Nws raws li polyacrylates, pigments thiab dej. Lub macromolecules nyob hauv nws yog tais rau hauv cov khoom pob khoom, uas tsim ib qho kev faib tawm dej. Polyacrylic polymers yog siv los ua ib phau ntawv thiab ua yeeb yaj kiab.
Muaj pes tsawg leeg thiab cov khoom siv ntawm cov xim acrelic facade rau phab ntsa
Qhov xub thawj thiab lub ntsiab ntawm cov xim muaj acrylic yog ib zaj duab xis-ua tus sau. Nws muab cov xim nws lub ntsiab yam ntxwv - qhov kev muaj peev xwm kom zoo adhesion nrog cov nplaum yuav tsum pleev xim.

- Txheej zog;
- ceev kom qhuav;
- haum rau kev siv ntawm cov ntxeem;
- dej thiab pa khov;
- tsis kam hloov mus rau qhov txawv txav thiab atmospheric phenomena.
