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. Product specifics transparent 2K epoxy system very long pot life, low viscosity solvent-free, phenol-free, free from benzyl alcohol very good wetting properties 5 cm layer thickness per grout (at max. 23 ° C MT & RT) possible, 2 cm per grout up to + 40 ° C curing temperature very good self-venting properties minimized hardening shrinkage due to low exothermic temperature development good chemical resistance and mechanical properties application areas Potting in thick layers Infusion & vacuum processes impregnate hand lamination

It is essential to protect surfaces from moisture (dew, condensation), dust, etc. during the curing time. ** Surfaces that have cured for a longer period of time must be sanded to ensure optimum adhesion properties.

storage Store in a cool, dry place at +20 to + 25 ° C. Products can be stored for 1 year in the original container. Always close the container tightly after removing the product. Due to its special properties and high purity, the resin is sensitive to cold. At storage or transport temperatures below + 15 ° C, fogging / highly visible cloudiness up to crystallization can occur. Please check the transparency of the resin before processing. Regeneration without loss of quality can be achieved by heat treatment. Regenerate the resin ideally at a maximum of + 55 ° C over a period of 24 hours in the delivery container. Slightly open the cap to allow pressure equalization. After cooling, apply the resin as usual. The hardener tends to form carbamates when exposed to oxygen and / or moisture. This cannot be regenerated, the hardener must be disposed of properly. Always close container tightly after use. Security notice Our epoxy resins and hardeners are classified and labeled as hazardous substances in accordance with REACH, CLP / GHS regulations. Danger and safety notices on the labels and the information in the safety data sheets must be observed. Disposal of residual materials and containers Liquid residual materials and containers with residual substances must be properly disposed of by the locally responsible hazardous waste disposal company (hazardous waste). Do not allow to get into groundwater or bodies of water. Only properly cured material may be disposed of with household or commercial waste.

Epinal UR 36.40 / UH 36.40

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.
