Mukuvaka kwemazuva ano kwemba refu uye mainjiniya emadziro makuru emaketeni, ma sealant ekuvaka anoshanda sezvinhu zvakakosha zvekubatanidza zvine simba, zvichisarudza zvakananga kuchengetedzeka kwechivako, kugadzikana uye hupenyu hwebasa remaenvelopu ekuvaka. Semutungamiri wepasi rose mukugadzira zvinhu zvemakemikari, ma sealant eSika structural silicone ave chigadzirwa chemuenzaniso wemapurojekiti ekubatanidza madziro emaketeni egirazi epamusoro pasi rose, anoshandiswa nekuda kwesimba rawo rekubatanidza rakakwirira, kuramba kwakanakisa kwekumanikidza uye kugadzikana kwechivako kwenguva refu. Kusiyana ne ma sealant ekushongedzera akajairika, ma sealant eSika structural akagadzirwa nehunyanzvi hwekubatanidza zvine simba, kuita mabasa ekubatanidza chivako asingaperi uye kutumira mutoro pakati pezvikamu zvekuvaka.
Sika structural sealant inoshandisa fomura yesilicone polymer yakachena uye tekinoroji yekurapa yakazvimirira, ine chinhu chimwe chete chinogadzirisa neutral, hapana ngura kusimbi, girazi, aruminiyamu alloy, matombo nezvimwe zvinhu zvekuvaka, uye hapana kukuvara kwezvinhu zvekuvaka zvepamusoro uye machira. Kushanda kwayo kukuru kuri muhunhu hwepamusoro hwemakanika, ine simba rakasimba rekusunga uye kuramba kuchekwa, izvo zvinogona kutakura huremu hwemapaneru egirazi uye kudzivirira mitoro yekunze senge mhepo yakasimba, kushanduka kwekushisa uye kugara kwechivako. Chigadzirwa ichi chinotsigira dynamic stress bearing kwenguva refu, kudzivirira kudonha kwegirazi, kusuduruka kwemapaneru uye kutsemuka kwechimiro kunokonzerwa nekukwegura nekukundikana kwesealant.
Panyaya yekuchinjika kwezvakatipoteredza, Sika structural sealant ine simba guru rekudzivirira mamiriro ekunze, inodzivirira mwaranzi ye ultraviolet, ozone erosion, kukwegura pakupisa kwakanyanya uye kuputsika kwekupisa kushoma. Inogona kuchengetedza kushanda kwakasimba kwekubatana kwechimiro muhurefu hwe -50℃ kusvika 150℃, isina kubvisa gum, kutsemuka kana kushanduka mushure memakumi emakore ekushandiswa panze. Kana ichienzaniswa neadhesives dzechimiro dzakajairwa dziri pamusika, ine simba rakasimba rekuchinja kushanduka, ichizadzisa zvinodiwa zvekuwedzera kwekupisa uye kushanduka kwekudzikira kwemadziro emadziro makuru munzvimbo dzakasiyana zvakanyanya dzekupisa, ichivimbisa kuchengetedzeka uye kuchengetedzwa kwemaenvelopu ekuvaka mugore rese.
Zvichinyanya kushandiswa pafuremu yakavanzika, furemu yakavanzika zvishoma uye madziro emachira egirazi anotsigirwa nepfungwa, madziro emachira ealuminium panel, madziro emachira ematombo nezvimwe zvivakwa zvepamusoro-soro, Sika structural sealants dzakapasa zvitupa zvakawanda zvepasi rose uye dzinosangana nezvinodiwa zvekuchengetedza zveinjiniya yekuvaka pasi rose. Nekuvandudzwa kuri kuitwa kwezvinodiwa zvekuchengetedza zvivakwa zvepamusoro-soro, Sika structural sealants dzakasimba uye dzakasimba dzave zvinhu zvinofanirwa kushandiswa pakutsigira zvivakwa zvepamusoro-soro uye mapurojekiti ekuvaka anozivikanwa, zvichipa vimbiso yakasimba yekuchengetedza zvivakwa zvemazuva ano zvekuvaka maguta uye kuchengetedza makwikwi asingaperi mumusika wekuvaka wepamusoro-soro.
