Amarangi yo mu nganda akoreshwa mu mazi ahanini akoresha amazi nk'umuti wayo ugabanya ubushyuhe. Bitandukanye n'amarangi akoreshwa mu mavuta, amarangi yo mu nganda akoreshwa mu mazi ntakenera imiti igabanya ubushyuhe nk'imiti ivura ubushyuhe n'imiti igabanya ubushyuhe. Kubera ko amarangi yo mu nganda akoreshwa mu mazi adashya kandi agaturika, ni meza kandi ni icyatsi kibisi, kandi nta VOC nyinshi akoreshwa, akoreshwa cyane mu nganda, nko mu biraro, mu byuma, mu modoka z'ubucuruzi, mu mashini z'ubwubatsi, mu ngufu z'umuyaga zikomoka kuri peteroli n'ahandi.

Abakora amarangi ashingiye ku mazi muri rusange bagabanya amarangi y’inganda ashingiye ku mazi mu marangi ashingiye ku mazi ya alkyd, amarangi ashingiye ku mazi ya acrylic, amarangi ashingiye ku mazi ya epoxy, amarangi ashingiye ku mazi ya acrylic, amarangi ashingiye ku mazi ya acrylic, amarangi ashingiye ku mazi ya amino, n’amarangi ashingiye ku mazi atagira umwimerere. Ashobora kugabanywamo ubwoko bwo kwiyumisha, ubwoko bwo guteka n’ubwoko bwo gusiga amarangi mu mazi.

Irangi rya alkyd resin rishingiye ku mazi rifite imiterere yo kuma vuba kandi rikora neza cyane mu kurinda, kandi rishobora gukoreshwa mu gukingira hasi ibintu by'icyuma. Irangi rishobora gukoreshwa mu gukingira, gukingira, gukingira n'ubundi buryo. Ubu bwoko bukoreshwa cyane mu gukingira ibikoresho byo mu nzu, chassis y'imodoka, n'amasoko y'amababi y'imodoka, kandi rikwiriye cyane cyane gukingira ubuso bw'icyuma cyoherejwe mu mahanga.

Ikintu cy'ingenzi kiranga irangi rya acrylic rishingiye ku mazi ni uko rifata neza kandi ntirizongera ibara, ariko rifite ubushobozi bwo kudashira no kudakoresha imiti. Kubera ko rihendutse kandi rifite ubuziranenge buke, rikoreshwa cyane ku byuma bifite ububengerane buke kandi bifite imiterere mito.

Irangi rya epoxy resin rikozwe mu mazi ntiririmo ibintu byangiza nka benzene, formaldehyde, lead, mercure, nibindi. Rifite imiterere ikomeye, rifata neza, rirwanya ingese neza, kandi ririnda ubushyuhe n'umutekano mwiza w'ibicuruzwa. Iterambere n'ikoreshwa ryaryo ni byo bigezweho mu iterambere ry'ibirahure byo mu mazi.

Amarangi yo mu nganda agizwe ahanini n'ibinyabutabire by'amazi bigizwe na amine na alkyd. Uretse imiterere y'irangi rikozwe mu mazi, iri barangi rikozwe mu mazi rifite ubwiza budasanzwe kandi bwuzuye, kandi imikorere yaryo ntaho itandukaniye n'iy'amine gakondo. Ariko, rigomba gutekwa mu gihe cyo kuritunganya, ari nabyo bibi by'iki gicuruzwa.
