MS resin 920R
MS resin 920R
NHUNGAMIDZO
920R is silane yakagadziridzwa polyurethane resin yakavakirwa pahupamhi hwema molecular weight polyether, inopera-yakavharwa ne siloxane uye ine carbamate mapoka, ine maitiro ekuita basa rakakwirira, hapana dissociative isocyanate, hapana solvent, yakanakisa adhesion uye zvichingodaro.
920R yekurapa michina ndeye kurapa mwando.Catalysts inodiwa mukugadzira sealant.Ordinary organotin catalysts (senge dibutyltin dilaurate) kana chelated tin (yakadai se diacetylacetone dibutyltin) inogona kuwana yakanaka mechanical properties.Iyo yakakurudzirwa huwandu hwemarata ekugadzirisa ndeye 0.2-0.6%.
920R resin yakasanganiswa neplasticizer, nano calcium carbonate, silane coupling agent uye mamwe mafirita uye ekuwedzera anogona kugadzirira sealant zvigadzirwa zvine simba rekusimba re2.0-4.0 MPa, 100% modulus pakati pe1.0-3.0 MPa.920R inogonawo kushandiswa kugadzirira zvisimbiso zvakajeka izvo zvinoshandiswa zvakanyanya mukuvaka kunze kwemadziro, kushongedza kwemba, maindasitiri elastic sealant, elastic adhesive zvichingodaro.
