Vaatleme kahte silikoonit\u00fc\u00fcpi ning nende kasutuskohti allj\u00e4rgnevalt l\u00e4hemalt.<\/p>\n\n\n\n<p><strong>Erinevus ei seisne ainult l\u00f5hnas<\/strong><\/p>\n\n\n\n<p>Nii neutraalsed kui ka happelised \u00fchekomponentsed silikoonid tarduvad \u00f5huniiskuse toimel. Kuigi tardunult n\u00e4ivad m\u00f5lemad \u00e4ravahetamiseni sarnased, esineb nende vahel rida olulisi erinevusi, mida tuleks enne kasutamist teadvustada ja selgeks teha, et seej\u00e4rel oskas juba vastavalt kasutuskohale sobiva toote valida.<\/p>\n\n\n\n<p>Paljude jaoks seisneb neutraalsete ja happeliste silikoonide erinevus vaid l\u00f5hnas. Nagu nimigi viitab, siis happeliste silikoonide tardumisel on tunda tugevat \u00e4\u00e4dikhappe l\u00f5hna. Neutraalsete silikoonide puhul on eralduvad \u00fchendid spetsiifilise magusapoolse aroomiga v\u00f5i praktiliselt l\u00f5hnatud. See tuleneb neutraalsete silikoonide oksiim- v\u00f5i alkoks\u00fc tardumiss\u00fcsteemist.<\/p>\n\n\n\n<p>Ainult l\u00f5hnak\u00fcsimusega kahe silikooniliigi erinevused ei piirdu. Happelised silikoonid ei sobi kasutamiseks kokkupuutes katmata metallidega, kuna tardumisel eralduv \u00e4\u00e4dikhape v\u00f5ib p\u00f5hjustada korrosiooni. Samuti ei ole soovitatav kasutada happelisi silikoone tsemendi baasil toodetega (nt betoon, krohvitud pinnad, ehitusplokid jne), kuna peale tardumist ei oma need piisavat naket antud pindadega. Neutraalsed silikoonid seevastu nakkuvad eelpool nimetatud materjalidega v\u00e4ga h\u00e4sti ja seega saab neid ka oluliselt enamates kasutuskohtades tarvitada.<\/p>\n\n\n\n<p><strong>Millisel juhul tuleks eelistada \u00fcht v\u00f5i teist tardumiss\u00fcsteemi?<\/strong><\/p>\n\n\n\n<p>Asjatundmatule inimesele v\u00f5iks vastata, et kahtluse korral tasuks alati eelistada neutraalset silikooni. Seda just eelpool kirjeldatud omaduste t\u00f5ttu. Kui k\u00f5rvale j\u00e4tta eritooted spetsiifilisteks rakendusteks, siis v\u00f5ib v\u00e4ita, et neutraalsed silikoonid t\u00f6\u00f6tavad suurep\u00e4raselt ka kohtades, kuhu soovitatakse happelisi silikoone. Vastupidi aga ei pruugi see v\u00e4ide aga kehtida. Tihendamist\u00f6\u00f6d metallist <em>sandwich<\/em>-paneelide \u00fchenduskohtades, aknapleki paigaldamisel, ventilatisoonit\u00f6\u00f6del, betoonfassaadide ning m\u00fc\u00fcritiste vuukides on vaid m\u00f5ningad n\u00e4ited, kus korrektselt paigaldatud neutraalne silikoon t\u00f6\u00f6tab, kuid happeline mitte.<\/p>\n\n\n\n<p>Siiski ei maksa unustada, et on kasutuskohti, kus happelised silikoonid t\u00e4idavad suurep\u00e4raselt neile esitatud ootusi ning on ainu\u00f5igeks valikuks. N\u00e4iteks sanitaarruumide tihendamist\u00f6\u00f6del, kus peamiselt kasutatavateks materjalideks on keraamilised plaadid, klaas, anodeeritud alumiinium, sobivad happelised silikoonid ideaalselt ning omavad ka teatavat hinnaeelist neutraalsete silikoonide ees. Lisaks ka klaas-klaas \u00fchenduste, n\u00e4iteks klaasvaheseinte, hermetiseerimist\u00f6\u00f6d, kus tuleb v\u00e4lja \u00fcks happelise silikooni eelis v\u00f5rreldes neutraalsega- nimelt on happeline v\u00e4rvitu silikoon oluliselt l\u00e4bipaistvam kui analoogne neutraalne silikoon.<\/p>\n\n\n\n<p>Kokkuv\u00f5tlikult v\u00f5ib \u00f6elda, et silikooni valides on oluline esmalt m\u00f5elda, mis kasutuskohta seda vaja on ning milliste materjalidega see nakkuma peaks.
