The casting resins used for hobby and art are very special epoxy products, whose properties are specially adapted to the unique requirements of casting decorative elements, figures, molds, and other areas of application. With the subsequent information, we might wish to show you clearly during which areas epoxy casting resins are often used, and which details you ought to consider when buying.
Casting resin may be a relatively low-viscosity resin that’s always mixed fresh from two components before processing: the particular resin in liquid form and an identical hardener. Once these two ingredients are mixed together, a reaction is about in motion. This not only releases heat, but also allows the mass to harden completely after a particular time.
The most desirable feature of casting resin is precisely its thin consistency. This makes it possible for the casting resin to penetrate even the littlest gaps and cavities and fill them. However, casting resin with a very low viscosity also takes a extended time to harden. If you would like to shop for such a casting resin, you almost certainly have already got a concrete project in mind.
Buy the proper Clear Casting Resin for each Project
Resins are available during a big variety of products from special dealers and on the web. However, these are often named with very different product names. This makes it quite difficult to differentiate between special clear casting resins and other epoxy resins. After all, these products are sometimes also mentioned as laminating resins, topcoats, or gelcoats in reference to possible areas of application. If, thanks to misunderstandings or misleading designations, an unsuitable resin is then purchased, this might well prove costly.
Differences between Casting Resin and epoxy (Laminating Resin)
These are the most differences between casting resins and epoxy resins:
Relatively low viscosity
Longer working time and also longer curing time
Casting of thicker layers in one operation is feasible
Layers of paint mix more quickly with a thinner consistency
More viscous than casting resin
Significantly shorter curing time
Therefore also rather short time interval
Only relatively thin layers up to a maximum of two cm should be poured directly
Different color layers are often better distinguished from one another thanks to the viscous consistency
Which Projects are often executed with Casting Resin?
To avoid unpleasant surprises during the work or afterward, the question of the proper material should be clarified beforehand for Cromas special paints & resins and epoxy resin chemistry. Casting resin in its various product variants is essentially suitable for the subsequent areas of application:
the production of river tables/casting resin tables
the creation of resin jewelry
the casting of molds or the casting of cast resin figures in silicone molds
Pouring of objects of all types
the filling of cracks and cavities in wooden work-pieces with casting resin
Coloring Transparent epoxy resin
Transparent epoxy resin is usually still mixed with paint after mixing resin and hardener so as to be utilized in the specified color shade. However, when choosing the colors you ought to pay close attention as to if they’re really suitable to be used together with the casting resin.
Transparent epoxy resin is ideal for the following applications:
Outdoor protective coatings
Autolevelling transparent epoxy resin
Impregnation of technical fabrics (fiberglass, carbon fiber, Kevlar).
Safety also Comes First when Working with Resin
Although most synthetic resins are largely harmless after complete curing, their processing is certainly related to certain health risks. You ought to therefore never allow liquid casting resin or its components to return into direct contact together with your skin. Nitrile gloves that are freed from holes and cracks are therefore indispensable. You ought to also protect your eyes with suitable safety glasses. Albeit your workplace is well ventilated, we recommend that you simply wear a respiratory mask to guard against toxic vapors.
