INTSHAYELELO

I-920R i-silane eguqulelwe i-polyurethane resin esekelwe kwi-polyether ephezulu ye-molecular weight, i-end-capped kunye ne-siloxane kwaye iqulethe amaqela e-carbamate, ineempawu zemisebenzi ephezulu, i-isocyanate ye-dissociative, i-solvent, i-adhesion egqwesileyo kunye nokunye.

I-920R yokunyanga indlela yokunyanga ukufuma. Ii-Catalysts ziyafuneka ekuqulunqweni kwe-sealant. I-organotin catalysts eqhelekileyo (efana ne-dibutyltin dilaurate) okanye i-chelated tin (njenge-diacetylacetone dibutyltin) inokufezekisa iimpawu ezintle zomatshini. Isixa esicetyiswayo se-tin catalysts yi-0.2-0.6%.

I-resin ye-920R edibeneyo kunye ne-plasticizer, i-nano calcium carbonate, i-agent yokudibanisa i-silane kunye nezinye izizalisi kunye nezongezelelo zingalungiselela iimveliso ze-sealant ezinamandla anamandla e-2.0-4.0 MPa, i-100% modulus phakathi kwe-1.0-3.0 MPa. I-920R ingasetyenziselwa ukulungiselela izitywini ezicacileyo ezisetyenziswa ngokubanzi ekwakheni udonga lwangaphandle, ukuhlobisa ikhaya, i-industrial elastic sealant, i-adhesive elastic njalo njalo.
