Nhasi, mavara akashongedzwa akawanikwa zvikuru. Iyi emulsions inobatanidza zvinhu zve watercolors namafuta. Mukugadzirwa kwavo vanofananidza mapiritsi emafuta, uye, semvura yakadzika, inonaya nemvura. Zvinotoshamisa kuti mushure mekuoma, havakwanisi kuvharwa. Acrylic paints yakasiyana nemuvara wakazara, iyo kwenguva yakareba haifaniri uye haina kuderera. Uye zvinogona kushandiswa zvachose pane imwe nzvimbo pamusoro. Ipine haisi chepfu uye hauna kunhuhwirira. Vanodzingwa nyore nyore kubva kune zvishandisi kana apedza basa.

Acrylic lacquer inowanzoshandiswa mumushandisi wekuvaka. Ichi chinokonzerwa nemvura yakasvibiswa inogadzirwa kubva mumhando yakakwirira resins pamwe nekuwedzera kwekuwedzera zvinhu. Acrylic varnishes inoshandiswa zvose pakudzivirira nzvimbo dzehuni kubva pane zvakasiyana-siyana zvinokuvadza, uye pakuita mabasa ekugadzira uye kupedza. Chimwe chinhu chinokosha chemas emulsions iyi kukurumidza kukurumidza. Iyo yakasvibiswa nemvura uye inoshandiswa kumusoro zvose zviri mumvura uye mumhepo inopisa. Mushure mokupwa, lacquer ye acrylic inoumba kunyange, zvishoma nezvishoma pamusoro pekunze kwepamusoro iyo isingasviki kupera. Zvinokwanisika kushambidza emulsion chete nechinangwa chakakosha. Icho hachichinje ruvara rwe substrate, asi, pane zvinopesana, rinosimbisa mufananidzo wemuti. Acrylic varnishes vane chiremera chakasimba chekudzivirira mazai eUV, migumisiro yemarudzi akasiyana-siyana ekuchenesa uye unyoro. Mukuwedzera, ivo vanodhura zvikuru.

Chii chinonzi acrylic, kwete nekunzwa, vamiririri vazhinji vehafu yakanaka yevanhu vanoziva. Izvi zvinyorwa zvinoshandiswa mukanakisa salons kwezvipikiri zvembambo. Mukadzi marigolds akaitwa nema acrylic ane simba, akanaka uye chaiwo.

Nokuda kwezvinhu zvayo zvakasiyana, iyi inonzi polymer yakatora nzvimbo inotungamirira munzvimbo dzakawanda dzehupenyu hwehupenyu.
