Chosungunulira bwino cha mapiritsi a shellac ndi mowa wocheperako wokhala ndi hydroxyl, monga methanol ndi ethanol. Insoluble mu glycol ndi glycerol, sungunuka mu lye, ammonia, komanso sungunuka m'munsi carboxylic zidulo, monga asidi formic ndi asidi asidi, insoluble mu mafuta, onunkhira hydrocarbons ndi zotumphukira zake halogen, carbon tetrachloride, madzi, sulfure dioxide amadzimadzi njira. Utomoni wa Shellac umawonongeka m'malo achilengedwe. Kutuluka m'madzi kumapangitsa kuchuluka kwa okosijeni m'zamoyo zam'madzi, kupanga madzi eutrophication, ndikupangitsa madzi kukhala ofiira.

1.Muzakudya, shellac imagwiritsidwanso ntchito muzovala zosungira zipatso zatsopano kupanga mafilimu owala, kuwonjezera moyo wa alumali wa zipatso, ndikuwonjezera mtengo wawo wamalonda. Shellac amagwiritsidwa ntchito popaka makeke ndi makeke kuti awonjezere kuwala, kuteteza chinyezi kuyambiranso, ndikupaka makoma amkati a zitini zachitsulo kuti chakudya zisakhumane ndi zitsulo.
2.Shellac ikhoza kugwiritsidwa ntchito kwambiri muzakudya, mankhwala, asilikali, magetsi, inki, zikopa, zitsulo, makina, nkhuni, mphira, ndi mafakitale ena.
Utoto wa 3.Shellac uli ndi zomatira zolimba ndipo umagwiritsidwa ntchito muzinthu zambiri zapamwamba zamatabwa ndi zokongoletsera.
4.Shellac imagwiritsidwa ntchito muzitsulo zachikopa monga mapeto owala ndi otetezera, omwe amadziwika ndi kuyanika mofulumira, kudzaza mwamphamvu, ndi kumamatira mwamphamvu ku zikopa, zomwe zimapangitsa kuti zikhale zofewa komanso zowonjezereka.
5. M'makampani opanga magetsi, shellac imagwiritsidwanso ntchito popanga mapepala otsekemera, mapepala a mica laminated, zotetezera magetsi pansi, ma vanishi otsekemera, mababu, nyali za fulorosenti, ndi solder pastes kwa machubu amagetsi.
6.M'makampani ankhondo, shellac imagwiritsidwa ntchito makamaka ngati retarder kwa othandizira zokutira, zida zotetezera, ndi mankhwala amfuti. Shellac imagwiritsidwanso ntchito popanga zida zankhondo zomwe zili ndi UV- ndi radiation-proof.
7.Shellac imagwiritsidwa ntchito makamaka ngati zokutira pamwamba kapena zodzaza zinthu za rabara mumsika wa rabala. Sinthani mavalidwe, mafuta, asidi, madzi, ndi kutsekereza. Chepetsani ukalamba ndikukulitsa moyo.
20 makilogalamu / katoni, 50 makilogalamu / thumba kapena malinga ndi zofuna za makasitomala.
