Tshawb Pom Cov Kev Ntseeg ntawm Alkyd Xim: Tus Kws Tshaj Lij Qhia
Alkyd xim muaj ntau yam tshwj xeeb uas ua rau nws sawv tawm ntawm lwm hom xim, suav nrog:
- Smooth tiav: Alkyd xim muaj ib tug du thiab glossy tiav uas yog unmatched los ntawm lwm hom xim.
- Kev Pabcuam: Alkyd xim tuaj yeem npog qhov chaw hauv ib lossis ob lub tsho loj, ua rau nws yog qhov kev xaiv nrov rau cov neeg pleev kob.
