MS resin 920R
OLELO HOOLAHA
ʻO 920R he silane polyurethane resin i hoʻololi ʻia e pili ana i ka polyether molecular kaumaha kiʻekiʻe, hoʻopau ʻia me ka siloxane a loaʻa nā hui carbamate, loaʻa nā ʻano o ka hana kiʻekiʻe, ʻaʻohe isocyanate dissociative, ʻaʻohe mea hoʻoheheʻe, adhesion maikaʻi a pēlā aku.
ʻO 920R ka hana hoʻōla ʻana i ka maʻamau.Pono nā catalysts i ka hoʻokumu ʻana i ka sealant.Hiki i nā mea hoʻoheheʻe organotin maʻamau (e like me ka dibutyltin dilaurate) a i ʻole ka tin chelated (e like me ka diacetylacetone dibutyltin) hiki ke loaʻa nā waiwai mechanical maikaʻi.ʻO ka nui i manaʻo ʻia o nā catalysts tin he 0.2-0.6%.
920R resin i hui pū ʻia me ka plasticizer, nano calcium carbonate, silane coupling agent a me nā mea hoʻopihapiha a me nā mea hoʻohui e hiki ke hoʻomākaukau i nā huahana sealant nona ka ikaika tensile o 2.0-4.0 MPa, 100% modulus ma waena o 1.0-3.0 MPa.Hiki ke hoʻohana ʻia ʻo 920R no ka hoʻomākaukau ʻana i nā sealants māmā i hoʻohana nui ʻia i ke kūkulu ʻana i ka paia o waho, ka hoʻonani hale, ka mea hoʻopaʻa elastic elastic, elastic adhesive a pēlā aku.

E kau ma kahi ʻoluʻolu a me ka makani. ʻAʻole wehe ʻia ka mālama ʻana i ka lumi wela. ʻO ka manawa mālama huahana no nā mahina 12. ʻO nā waiwai hiki ʻole ke puhi ʻia, e like me ka halihali kemika maʻamau.
