## Description

LET'S RESIN

Review: Love this brand of Resin!
Review: This resin is of medium viscosity and clear. I have used it on 3-D printed models to fill gaps between parts. It polymerizes well and fast with a 365 nm UV light. Most lights are at 395nm, so to obtain good results, I recommend also purchasing a 365 nm UV light source.

*by S***R on 19 November 2025*

Super Zeug. Nur sollte man drauf achten keine allzu tiefen Schablonen zu verwenden und vorallem durchsichtige. Aber wenn man Ebene um Ebene dünn aufträgt und mit der Lampe trockenen lässt klappt das ganz gut. Härtet auch sehr schnell aus, ich benutze dafür eine Nagellampe für UV Lacke. In den Fotos die Lampe die ich benutze und im zweiten sind die Drachen mit mit dem Resin und etwas lidschatten gemacht. Nice-to-Know: Übrigens braucht der Lidschatten-Resin Mix länger für die Härtung, weil die Lichtwellen dann nicht mehr so gut durch den Resin kommen
