Muri iki gihe, TDI cyangwa MDI byatoranijwe kuba ibikoresho byibanze byibicuruzwa byinshi bya PU, byaba umukozi, byoroshye kandi bikomeye, delastique, uruhu rwa PU cyangwa pu baramba. Humwenda,haba kuriTDIorMdi, yayoImpeta ya Benzenemuri TDI na MDIGuhuza nezasKuri BitandukanyeIsocyanesteramatsinda, kandi pin yahujwe hamwe na NCO. Munsi ya lIly, ubushyuhe, ogisijeni, cyane cyane imirasire ya ultraviolet, irairashobora gutera Ammona ester ihuza kuboranakubyara Aromatic Amine, ahobenzene nucleusgusubirwamo nyumaokiside. Ibi byabyara amatsinda ya chromophoric bitera umuhondo kubicuruzwa byanyuma bya PU.Ijisho ryumuntu ryumva neza ibara, mubisanzwe ppm nkeya yumwanda wamabara azaganisha ku bicuruzwa byumuhondo.
Kugirango ukemure ikibazo cyumuhondo, uburyo bwingenzi ni ugukoresha HDI cyangwa IPDI aho kuba TDI na MDL nkibikoresho bibisi bidafite umurongo utaziguye hagati ya bejezene Impeta na NCO. Ariko igiciro cyibikoresho fatizo gifite ibibi: Igiciro kirahenze, kirwanya imiti irwanya imiti, ikarishye ntabwo ihagije .... Ibi bigabanya cyane kuzamurwa kwa HDI kuri PU.
Ikindi gisubizo nukuzuza gaze ya inert mugikorwa cyumusaruro nububiko kugirango utandukane umubano na ogisijeni bishoboka. Uburyo bwiza cyane ni ukukongeraho antioxidant kandiUV Gushaka, niki gishobora gukumira neza no gutinza ibintu bya PU umuhondo.
Yihoo HN130 ni Amine Anti-Umuhondo. Ni's yakoreshejweNka stabilizer ya gaze mubikorwa byo gukora, bifite neza kuri nitric oxide (oya)naNitrogden Dioxyde (No2),nagukumira nezaumuhondo watewe nafugunging.
Yihoo HN130 Yakoreshejwe cyane muri PUIbikoresho byo kubumbaIbikoresho byo mu nk inkweto, Plastike, Polyurethane Fibre na Polyurethane no Gukuramo Polinethane, kwagura cyane ubuzima bwa serivisis.
