Moloko o mocha oa li-silicone tse phekolang UV le li-epoxies li ntse li sebelisoa haholo lits'ebetsong tsa likoloi le tsa elektroniki.
Ketso e 'ngoe le e 'ngoe bophelong e kenyelletsa ho fapanyetsana: Ho fumana molemo o mong ka litšenyehelo tsa o mong, ho finyella litlhoko tsa boemo bo teng ka ho fetisisa. Ha boemo bo kenyelletsa maqhama a mangata, ho tiisa kapa ho kenya gasketing, bahlahisi ba itšetleha ka li-adhesives tsa UV hobane li lumella ho hlokomeloa le ho fola kapele (metsotsoana e 1 ho isa ho e 5 ka mor'a ho pepeseha ha leseli).
Leha ho le joalo, khoebo ea khoebo ke hore li-adhesives tsena (acrylic, silicone le epoxy) li hloka substrate e bonaletsang hore li tlamahane hantle, 'me li bitsa chelete e ngata ho feta likhomaretsi tse phekolang ka mekhoa e meng. Leha ho le joalo, bahlahisi ba bangata liindastering tse ngata ba entse khoebo ena ka thabo ka lilemo tse mashome a 'maloa. Likhamphani tse ling tse ngata li tla etsa joalo bakeng sa bokamoso bo lebelletsoeng. Phapang, leha ho le joalo, ke hore lienjineri li tla ba le monyetla oa ho sebelisa sekhomaretsi sa silicone kapa epoxy UV-pheko, joalo ka e thehiloeng ho acrylic.
"Le hoja re entse li-silicone tse phekolang UV lilemong tse leshome tse fetileng, lilemong tse tharo tse fetileng re ile ra tlameha ho matlafatsa boiteko ba rona ba ho rekisa ho tsamaisana le tlhoko ea 'maraka," ho bolela Doug McKinzie, motlatsi oa mopresidente oa lihlahisoa tse khethehileng Novagard. Litharollo. "Thekiso ea rona ea silicone ea kalafo ea UV e eketsehile liperesente tse 50 lilemong tse 'maloa tse fetileng. Sena se tla fokotsa ba bang, empa re ntse re lebeletse khōlo e ntle lilemong tse ’maloa tse tlang.”
Har'a basebelisi ba kholo ka ho fetisisa ba li-silicone tse phekolang UV ke li-OEM tsa likoloi, le barekisi ba Tier 1 le Tier 2. Mofani a le mong oa Tier 2 o sebelisa Loctite SI 5031 sealant ho tloha Henkel Corp. ho kenya li-terminals tse ka har'a matlo bakeng sa li-module tsa elektronike tse laolang mariki le li-sensor tsa khatello ea mabili.
