He rauemi matū tino pai te Trimethylolpropane (TMP) me ōna tono whānui, tae atu ki ngā mara pēnei i ngā kapia alkyd, ngā polyurethane, ngā kapia kore mākū, ngā kapia polyester, me ngā paninga. Hei tāpiri, ka whakamahia te TMP i roto i te hanga hinu whakahinuhinu rererangi, ngā waituhi tā, ā, ka mahi hei āwhina kakahu me te whakaū wera mō ngā kapia polyvinyl chloride (PVC).
Hei whakaroa mekameka e whakamahia whānuitia ana i roto i te umanga kapia, he hua matua te TMP e akiaki ana i te whakapai ake ahumahi o te rāngai polyols. Nā tōna hanganga ngota ahurei ka iti te ira rewa me ngā āhuatanga polyol rite ki te glycerol. Kāore e taea e te TMP te whakakapi i te glycerol i roto i te hanganga o ngā kapia alkyd engari ka taea hoki te mahi tahi me ētahi atu polyols pērā i te neopentyl glycol me te pentaerythritol, ka whakanui ake i te whānuitanga o ngā momo kapia alkyd. Ka whakarei ake tēnei whānuitanga i te mahi me te urutau o ngā hua e ahu mai ana i te kapia, ka whakaū i te tūranga matua o te TMP ki te whakatairanga i te auahatanga rauemi me te whai huatanga o te tono puta noa i ngā ahumahi.
Ko ngā kapia alkyd i hangaia mā te whakamahi i te TMP he ātete tino pai ki te waikura, te pumau o te waikura, te ātete ki te kawakore, me te pumau o te wera, he mea tino pai mō te hanga peita tohu rori. E whakamahia whānuitia ana hoki ēnei i roto i te hanga peita topcoat mō ngā motuka, ngā pouaka whakamātao, ngā mīhini horoi, me ētahi atu taputapu whare. Hei tāpiri, he mahi nui tā TMP i roto i ngā tukanga whakaputa o ngā surfactants, ngā kaihoko whakamakuku, ngā mea pahū, ngā mea whakakoi kirihou, ngā kirihou whakakaha muka karāhe, ngā esters rosin, ngā hinu whakahinuhinu rererangi kounga teitei, ngā kaihoko tukatuka muka, ngā waituhi tā, me ngā pahuka polyurethane, e mahi ana hei whakaroa mekameka kapia, hei āwhina kakahu, me te whakaū wera mō ngā kapia PVC.
He whānuitia ngā whakamahinga o ngā hua o te TMP puta noa i ngā mara maha, hei hononga whakawhiti, hei whakamaroke, hei whakapūhui, hei tuku, me hei whakakorikori. E whakamahia ana hoki ēnei i roto i te hanganga o ngā irahiko kiriuhi wai me te whiriwhiringa teitei mō ngā katote konutai.
Ko te TMP te rauemi matua e whakamahia ana mō te hanga i ngā matū whakaora PU, te hanga i ngā paninga UV, me te hanga i ngā kapia alkyd kounga teitei. I Haina, neke atu i te 70% o te tapeke o te trimethylolpropane e whakamahia ana i roto i te whare. Hei tāpiri, he mahi nui tā TMP i roto i te hanga kapia polyester me te titanium dioxide.
Kei a TMP te tūranga matua i roto i te hanga o ngā kapia alkyd kounga teitei, e whakamahia whānuitia ana i roto i ngā peita motuka kounga teitei me ngā kaihoko whakaora-whakaahua mō ngā peita me ngā waituhi. I te mea kei te whakapai tonu te kounga o ngā hua i roto i ngā ahumahi motuka me ngā taputapu kāinga o Haina, kua tino piki ake te hiahia mō ngā paninga kounga teitei. I te wā kotahi, kua piki haere te kaha o ngā ture taiao kua akiaki i te tipu tonu o te hiahia mō ngā kaihoko whakaora-whakaahua. Nō reira, e matapaetia ana ka nui te tipu o te hiahia mō te TMP i ngā tau e haere ake nei.
