Hot tack<\/a>\u00a0je kl\u00ed\u010dovou vlastnost\u00ed\u00a0tepeln\u011b zataven\u00e1 vrstva<\/strong>, proto\u017ee ur\u010duje schopnost vrstvy odol\u00e1vat sil\u00e1m, kter\u00e9 se sna\u017e\u00ed odd\u011blit t\u011bsn\u011bn\u00ed, kdy\u017e je je\u0161t\u011b v hork\u00e9m stavu. Tato vlastnost m\u00e1 zna\u010dn\u00fd v\u00fdznam zejm\u00e9na v procesech, jako je vertik\u00e1ln\u00ed pln\u011bn\u00ed a ut\u011bs\u0148ov\u00e1n\u00ed (VFFS).<\/p>\n

Vlastnost lepivosti za horka je d\u016fle\u017eit\u00e1, proto\u017ee tato situace nast\u00e1v\u00e1 u vertik\u00e1ln\u00edch obal\u016f s tvarovou v\u00fdpln\u00ed a t\u011bsn\u011bn\u00edm, p\u0159i nich\u017e nen\u00ed k dispozici mnoho \u010dasu na ochlazen\u00ed.<\/p>\n
