Epoxy Resin Guide (2)
Which Resin Perfect for My Project?
First of all, this question is about the material properties that characterize a particular epoxy resin mixture. You should, therefore, be able to estimate how the epoxy resin can be processed and worked within the liquid and cured state on the basis of the instructions
Low-viscosity Epoxy Resins / Casting Resins
Caution is required when dealing with viscosity: This term describes the flowability of liquids. Accordingly, we speak of low viscosity when a liquid is particularly thin and flowable. So if you need a particularly fluid resin, you should buy a low viscosity resin. The property of a nearly watery consistency can be very important for some applications, e.g. if you want to cast molds or for the production of river tables.
However, the low viscosity of these resin variants means that they cure very slowly. You should, therefore, plan for longer time intervals for the next processing steps. But you also have much more time and no stress during processing. After all, low-viscosity epoxy resin usually only hardens after 12 to 24 hours. Since the exothermic chemical process of transformation is so slow, relatively little heat is released. Thus, in contrast to high-viscosity or medium-viscosity epoxy resins, thicker layers and larger quantities of the material can be processed in one operation without any problems.
Fields of Application for Casting Resin
- Casting of all kinds of molds
- Production of epoxy resin jewelry
- Molded parts in the field of model making
- Furniture such as epoxy resin tables and resin river tables
- Filling cracks and holes in wood
- Epoxy resin floors in living areas or garage floors
High-viscosity Epoxy Resins / Laminating Resins
Many thicker and therefore highly viscous or medium viscous epoxy resins are reminiscent of honey with their tough consistency. Product variants in this category are often explicitly referred to in the trade as laminating resin or epoxy resin and are particularly suitable for coating surfaces. However, they can also be used to undertake projects in the field of resin art and resin geodes. With highly viscous resins you should definitely take the manufacturer’s instructions regarding the maximum layer thickness of a work step seriously. In many cases, a layer thickness of 1 to 2 cm should not be exceeded for problem-free processing.
Application Areas for Laminating Resin
- Resin art, i.e. the casting of pictures with resin
- Deco objects like Resin Geodes and Resin Petri Dishes
- Finishing of paintings and works of art of all kinds
- Certain variations of resin jewelry
- Sealing of surfaces such as worktops or tables
