Ko ta tatou RE, e kiia ana ko TTI, he otinga kei roto 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate me te 72.5% ethyl acetate. He kaihoko whakaora/whakawhitiwhiti mo te whakapiri i runga i te polyurethane hydroxyl, rapa maaori me te rapa waihanga, he pai rawa mo te hono i nga rawa rapa. Kei te whakamahia whānuitia hoki mo te whakapiri konganuku ki te rapa. I tua atu, ka taea te whakamahi RE i runga i te kapia, te antioxidant, te plasticizer, me etahi atu. I roto i te waahi whakapiri, ka whakamahia te RE hei kaihoko whakawhiti i runga i te whakapiri neoprene me te p hydroxyl polyurethane whakapiri i nga waahi hu. Ko te tikanga, mo te rongoa i te whakapiringa o nga wahanga 100 ma te taumaha (pbw) i runga i te nui o te 4-7 pbw RE. Ko te ora o te kohua o te whakapiri whakauru he tata ki nga haora.
Me whakamahi te whakapiri-waahanga e rua i roto i te waa e tika ana i muri i te whakaurunga ki roto RE. Ko te roa o te wa e tika ana ehara i te mea e pa ana ki te ihirangi polymer o te whakapiri, engari ano hoki etahi atu waahanga e tika ana (penei i te kapia, te antioxygen, te plasticizer, te whakarewa, me etahi atu. Ina tata ki te waa e tika ana, ko te nuinga o nga haora, kotahi ra mahi ranei, te whakapiri. ka uaua ake ki te whakahaere, ka piki ake te pokey Ka mutu, ka waiho hei tiēre e kore e taea te huri, te polyurethane Hydroxyl (te 20%), te horopeta RE 4-7. , To tatou RE mahi 4-7.
