Trimethylolpropane (TMP) ke thepa ea bohlokoa ea lik'hemik'hale tse ntle tse nang le ts'ebeliso e pharaletseng, e akaretsang masimo a kang li-resin tsa alkyd, li-polyurethane, li-resin tse sa koaheloang, li-resin tsa polyester le lipente. Ho feta moo, TMP e sebelisoa ho kopanyeng li-lubricant tsa lifofane, enke ea khatiso, 'me e sebetsa e le sesebelisoa se thusang le se matlafatsang sa masela bakeng sa li-resin tsa polyvinyl chloride (PVC).
Jwalo ka ketane e sebediswang haholo indastering ya resin, TMP ke sehlahiswa sa bohlokwa se kgannang ntlafatso ya indasteri ya lekala la polyols. Sebopeho sa yona se ikgethang sa dimolek'hule se e fa ntlha e tlase ya ho qhibiliha le dibopeho tsa polyol tse kang glycerol. TMP e ke ke ya nkela glycerol sebaka feela tlhahisong ya di-resin tsa alkyd empa hape e ka sebetsa mmoho le di-polyol tse ding tse kang neopentyl glycol le pentaerythritol, e leng se eketsang mefuta ya di-resin tsa alkyd. Ho feto-fetoha hona ho ntlafatsa tshebetso le ho ikamahanya le maemo ha dihlahiswa tse thehilweng ho resin, ho tiisa karolo ya bohlokwa ya TMP ho ntshetseng pele boqapi ba thepa le bokgoni ba tshebediso ho pholletsa le diindasteri.
Li-resin tsa alkyd tse lokisitsoeng ka ho sebelisa TMP li bontša khanyetso e ikhethang ea hydrolysis, botsitso ba oxidation, khanyetso ea alkali le botsitso ba mocheso, e leng se etsang hore li tšoanelehe haholo bakeng sa ho hlahisa pente ea matšoao a litsela. Li boetse li sebelisoa haholo tlhahisong ea pente ea topcoat bakeng sa likoloi, lihatsetsi, mechini ea ho hlatsoa le lisebelisoa tse ling tsa ntlo. Ho feta moo, TMP e bapala karolo ea bohlokoa lits'ebetsong tsa tlhahiso ea li-surfactants, li-agent tse kolobisang, li-explosive, li-plasticizer, li-plastiki tse matlafalitsoeng ka fiberglass, li-ester tsa rosin, li-lubricant tsa lifofane tsa boemo bo holimo, li-agent tse sebetsanang le fiber, li-enke tsa khatiso le li-polyurethane foam, li sebetsa e le extender ea ketane ea resin, thuso ea masela, le stabilizer ea mocheso bakeng sa li-resin tsa PVC.
Dintho tse tswang ho TMP di fumana ditshebediso tse pharaletseng masimong a mangata, tse sebetsang e le di-agent tse kopanyang, di-agent tse fodisang, di-emulsifier, di-agent tse lokollang, le di-catalyst. Di boetse di sebediswa tlhahisong ya di-electrode tsa lera la metsi tse nang le kgetho e phahameng bakeng sa di-ion tsa sodium.
TMP e sebediswa haholoholo e le thepa e tala bakeng sa ho hlahisa di-agent tse phekolang tsa PU, ho kopanya dikoahelo tsa UV, le ho etsa di-resin tsa alkyd tsa maemo a hodimo. Chaena, tshebediso ya yona e etsa karolo e fetang 70% ya tshebediso yohle ya lapeng ya trimethylolpropane. Ho feta moo, TMP e bapala karolo ya bohlokwa tlhahisong ya di-resin tsa polyester le titanium dioxide.
TMP e na le boemo ba bohlokoa tlhahisong ea li-resin tsa alkyd tsa maemo a holimo, tse sebelisoang hangata penteng ea likoloi tsa maemo a holimo le li-agent tse fofonelang lifoto bakeng sa lipente le li-enke. Ha boleng ba lihlahisoa indastering ea likoloi le lisebelisoa tsa lapeng tsa Chaena bo ntse bo ntlafala, tlhoko ea li-coat tsa maemo a holimo e eketsehile haholo. Ka nako e ts'oanang, melaoana e thata ea tikoloho e ntseng e eketseha e tsamaisitse kholo e tsitsitseng ea tlhoko ea li-agent tse fofonelang lifoto. Ka lebaka leo, tlhoko ea TMP e lebelletsoe ho ba le kholo e kholo lilemong tse tlang.
