Abstract. The hard resin was dispersed in water EP 384 W (Solutia-Vianova,
Austria) and cross-linked with aliphatic polyaminaduct hardener EH 623
W (Solutia-Vianova, Austria) and distilled water in a stoichiometric ratio
of 50:10:20, respectively.
The degree of the epoxy resin cross-linking and the quantity of unreacted
epoxy groups have been monitored by the FTIR spectroscopic method. The
optimal time of total cross-linking as the measure of the degree of cross-linking
was determined by indirect measuring of the film hardness (JUS.H.C8.055).
Key Words: Epoxy system, degree of cross-linking, FTIR spectroscopic
method, film hardness
ISPITIVANJE EMULGOVANIH VODENIH EPOKSI
SISTEMA
Čvrsta smola dispergovana u vodi EP384W (Solutia-Vianova, Austrija), umrežavana
je alifatičnim poliaminoadukt umreživačem EH623W (Solutia-Vianova, Austrija)
i destilovanom vodom, u stehiometrijskom odnosu 50 : 10 : 20.
Stepen umreženosti epoksi smole i kvantitet neprereagovalih epoksi
grupa praćeni su metodom FTIR spektroskopije. Optimalno vreme potpunog
umrežavanja, kao mera stepena umreženosti, određivano je merenjem tvrdoće
filma indirektnim putem (JUS.H.C8.055).
Ključne reči: Epoksi sistem, stepen umreženosti,FTIR spektroskopija,
tvrdoća filma.
