Abstract

L'INVENTION CONCERNE UNE POUDRE D'AGENT DE VIRAGE A BASE DE RESINE EPOXY BLOQUEE. LA RESINE EPOXY A UNE MASSE MOLECULAIRE EPOXY COMPRISE ENTRE 2000 ET 7500 ENVIRON ET COMPREND UNE RESINE EPOXY MODIFIEE OBTENUE PAR BLOCAGE DES GROUPES EPOXY D'UNE RESINE EPOXY D'UNE MASSE MOLECULAIRE EPOXY D'UN MAXIMUM DE 700 ENVIRON DANS DES PROPORTIONS CHOISIES. LA POUDRE EST PARTICULIEREMENT UTILISABLE DANS UN APPAREIL DE REPRODUCTION DE VOLUME IMPORTANT AVEC UN DISPOSITIF DE FIXATION PAR CONTACT ET PEUT ETRE FIXEE DE MANIERE EXCELLENTE A UNE TEMPERATURE EXTREMEMENT PEU ELEVEE EN QUELQUES CENTIEMES DE SECONDE.THE INVENTION RELATES TO A FIXING AGENT POWDER BASED ON A BLOCKED EPOXY RESIN. EPOXY RESIN HAS AN EPOXY MOLECULAR MASS OF ABOUT 2000-7500 AND INCLUDES A MODIFIED EPOXY RESIN OBTAINED BY BLOCKING THE EPOXY GROUPS OF AN EPOXY RESIN OF A MAXIMUM EPOXY MOLECULAR MASS OF APPROXIMATELY 700 IN SELECTED PROPORTIONS. THE POWDER CAN BE PARTICULARLY USED IN A REPRODUCING APPARATUS OF LARGE VOLUME WITH A CONTACT FIXING DEVICE AND CAN BE FIXED EXCELLENTLY AT EXTREMELY LOW TEMPERATURE IN A FEW HUNDRED OF A SECOND.
