MS cob 920R
Taw qhia
920R yog silane hloov kho polyurethane resin raws li qhov hnyav molecular polyether, kawg-capped nrog siloxane thiab muaj carbamate pawg, muaj cov yam ntxwv ntawm kev ua haujlwm siab, tsis muaj isocyanate dissociative, tsis hnyav, adhesion zoo thiab lwm yam.
920R curing mechanism yog noo noo kho.Catalysts yog xav tau nyob rau hauv sealant formulation.Ordinary organotin catalysts (xws li dibutyltin dilaurate) lossis chelated tin (xws li diacetylacetone dibutyltin) tuaj yeem ua tiav cov khoom zoo.Tus nqi pom zoo ntawm tin catalysts yog 0.2-0.6%.
920R resin ua ke nrog cov yas yas, nano calcium carbonate, silane coupling tus neeg sawv cev thiab lwm cov khoom ntim thiab cov khoom ntxiv tuaj yeem npaj cov khoom sib khi uas muaj zog tensile ntawm 2.0-4.0 MPa, 100% modulus ntawm 1.0-3.0 MPa.920R kuj tseem siv tau los npaj pob tshab sealants uas tau siv dav hauv tsev sab nrauv phab ntsa, kho kom zoo nkauj hauv tsev, kev lag luam elastic sealant, elastic nplaum thiab lwm yam.
