Epinal UR 36.40 / UH 36.40 Very good UV-resistant epoxy resin system

UR 36.40 / UH 36.40 is a very lightfast, transparent epoxy resin system for many casting applications. Due to the reduced reactivity of the system, layers up to 5 cm thick can be poured in one operation (material & room temperature max. 23 ° C). Even at a curing temperature of 40 ° C, layer thicknesses of 2 cm can be produced without any problems. Epinal UR 36.40 / UH 36.40 is also excellently suited as a low-viscosity impregnation system with a very long pot life (e.g. wood consolidation). It has excellent adhesion properties on various fabrics, foams, wood and mineral materials. Mineral fillers as well as light fillers can easily be added if necessary. Depending on the type of filler, this can extend or shorten the pot life, processing time and also the curing time. Translucent to opaque coloring without impairing the surface hardness is possible with Epinal Color Cream UR. Appropriate application tests with regard to the intended casting project are recommended.

Sehr gut UV-beständiges Epoxy Gießharzsystem

UR 36.40 / UH 36.40 ist ein sehr gut lichtbeständiges, transparentes Epoxyharzsystem für viele Gießanwendungen.

Durch die reduzierte Reaktionsfreudigkeit des Systems können Schichtstärken bis zu 5 cm in einem Arbeitsgang gegossen werden (Material- & Raumtemperatur max. 23°C).

Selbst bei einer Härtungstemperatur von 40°C sind Schichtstärken von 2 cm problemlos herzustellen.

Epinal UR 36.40 / UH 36.40ist auch als niederviskoses Imprägniersystem mit sehr langer Topfzeit hervorragend geeignet (z. B. Holzverfestigung). Es besitzt ausgezeichnete Haftungseigenschaften auf diversen Geweben, Schaumstoffen, Holz und mineralischen Werkstoffen.

Mineralische Füllstoffe sowie auch Leichtfüllstoffe können bei Bedarf problemlos bei-gemengt werden. Je nach Füllstoffart kann sich dadurch die Topfzeit, Verarbeitungszeit und auch die Härtungszeit verlängern bzw. verkürzen.

Transluzente bis deckende Einfärbung ohne Beeinträchtigung der Oberflächenhärte ist mittels Epinal Color Cream UR möglich.

Entsprechende Anwendungstests hinsichtlich des beabsichtigten Gießvorhabens werden empfohlen.
