Sehlahisoa se molemo ka ho fetisisa sa matlapa a shellac ke lino tse tahang tse tlaase tse nang le hydroxyl, tse kang methanol le ethanol. Ha e qhibilihe ka har'a glycol le glycerol, ha e qhibilihe ka har'a lye, ammonia, empa hape e qhibiliha ka har'a acid e tlase ea carboxylic, joalo ka asiti ea formic le acetic, e sa keneng ka har'a mafura, li-hydrocarbon tse nkhang hamonate le lihlahisoa tsa tsona tsa halogen, carbon tetrachloride, metsi, tharollo ea metsi a sebabole. Shellac resin e senyeha tikolohong ea tlhaho. Ho tsoa ka metsing ho tla baka keketseho ea oksijene ea lintho tse phelang metsing, ho etsa hore metsi eutrophication, 'me a etse hore metsi a be khubelu.

1.Ka indasteri ea lijo, shellac e boetse e sebelisoa ka ho roala litholoana tse hloekileng ho etsa lifilimi tse khanyang, ho lelefatsa bophelo ba litholoana, le ho eketsa boleng ba tsona ba khoebo. Shellac e sebelisoa ha ho etsoa confectionery le li-pastry coatings ho eketsa khanya, ho thibela mongobo hore o boele o be teng, le ho tlotsa mabota a ka hare a makotikoti a tšepe ho thibela lijo hore li se kopane le tšepe.
2.Shellac e ka sebelisoa haholo lijong, meriana, sesole, motlakase, enke, letlalo, metallurgy, mechine, lehong, rabara le liindasteri tse ling.
Pente ea 3.Shellac e na le sekhomaretsi se matla 'me se sebelisoa linthong tse ngata tse phahameng tsa mapolanka le mekhabiso.
4.Shellac e sebelisoa indastering ea letlalo e le qetello e khanyang le e sireletsang, e khetholloang ka ho omisa ka potlako, ho tlatsa ka matla, le ho khomarela ka matla ho letlalo, ho etsa hore e be bonolo le ho feta.
5. Lefapheng la motlakase, shellac e boetse e sebelisoa ha ho etsoa pampiri e sireletsang, mapolanka a mica a laminated, li-insulators tsa motlakase oa fatše, li-varnish tse sireletsang, li-bulbs, mabone a fluorescent le li-solder pastes bakeng sa li-tubes tsa elektronike.
6.Indastering ea sesole, shellac e sebelisoa haholo-holo e le retarder bakeng sa li-agent tsa ho roala, thepa ea ho itšireletsa le lithethefatsi tsa sethunya. Shellac e boetse e sebelisoa ho etsa lisebelisoa tsa sesole tse sa boneng mahlaseli a kotsi a UV le mahlaseli a kotsi.
7.Shellac e sebelisoa haholo-holo e le ho roala holim'a metsi kapa ho tlatsa lihlahisoa tsa rabara indastering ea rabara. Ntlafatsa moaparo, oli, asiti, metsi, le ho intša. Fokotsa botsofali le ho lelefatsa nako ea bophelo.
20 lik'hilograma / lebokose, 50 lik'hilograma / mokotla kapa ho ea ka litlhoko tsa bareki.
