GlassCast 50 Clear Epoxy Casting Resin
GlassCast 50 has been designed to be as easy-to-use and reliable as possible. It does not require degassing or any other special equipment and in fact will thoroughly degas itself during cure, resulting in a perfectly clear, bubble-free casting. GlassCast 50 uses a simple 2:1 mix ratio by volume meaning that it can be measured and mixed accurately requiring only marked buckets.
Even more remarkable is that GlassCast 50 can be poured into insulating materials (such as wood) at thicknesses up to 25mm in a single pour without overheating, distorting or discolouring. If even more thickness is required, multiple layers of up to 25mm each can be poured on top of each other – following partial cure of the previous layer – to create castings of unlimited thickness.
When not pouring into wood (plastic or silicone moulds for example) GlassCast 50 cast actually be used at thicknesses up to 50mm in a single pour.
Glass Cast 50 is incredibly clear, even at thicknesses of 50mm or more and uses the very latest UV stabilising technology to provide industry leading long-term yellowing protection*.
To create stunning translucent colours (like stained glass) just add a few drops of our resin tinting pigments. GlassCast can also be enhanced with a metal powders, glitters and glow powders to achieve a huge range of decorative effects.
IMPORTANT: Maximum Casting Thickness
When casting into wood the insulating effect of the wood (particularly if you also have a wooden base/board) can make it very difficult for the resin to lose heat as it cures. This limits the maximum recommended castable thickness when casting into wood at 25mm. This is particularly important when working in higher ambient temperatures (anything above 20°C).
For a typical ‘river table’ fill (example 40mm) we would suggest splitting the main pour into 2 layers of 20mm each, this will avoid the possible risk of exotherm during cure and achieve the best possible results.
When casting GlassCast 50 into other materials such as plastic or silicone moulds, it it usually possible to cast up to 50mm in thickness in a single pour.
GlassCast 50 can be used for just about any application that requires a water-clear, bubble-free and highly tough resin casting. It is the ideal product for clear casting resin for wood projects and is the perfect live edge river table epoxy resin.
It can be poured as a thick coating over existing surfaces or into moulds made from silicone rubber and of course it can be poured into knot-holes, cavities and gaps between wood for furniture pieces like epoxy river tables.
If you are looking for an epoxy resin to create jewellery – like wood and resin rings, pen blanks or 3D resin art, GlassCast® 10 would be more suitable.
- River tables / knot holes
- Wood and resin combination furniture (lamps, sculptures)
- Clear castings / sculptures
Pigments and Tints
To create stunning translucent colours (like stained glass) just add a few drops of our resin tinting pigments. GlassCast can also be enhanced with metal powders, glitters and glow powders to achieve a huge range of decorative effects. It is the perfect clear resin for crafts of all kinds.
Our Glass Cast range of resins are compatible with many pigments and colouring powders on the market today. This includes epoxy compatible pigment pastes, various pigment powders and translucent tinting pigments. If the pigment manufacturer is not sure if the pigment is epoxy compatible then a small test should give you the answer you need. We stock a range of pigments that have all been tested and work great with all of our Glass Cast resins. You can find our range of pigments at the links below.
- Translucent Tinting Pigments
- Pearl Ex Pigment Powders
- Opaque Epoxy Compatible Pigment Pastes
How to Use
GlassCast 50 should always be mixed, poured and cured at a constant room temperature of around 20°C. Resin and hardener should be mixed 2 parts resin to 1 part hardener by volume (calibrated mixing pots are available).
For castings, GlassCast 50 can be poured into common mould materials such as silicone**, polyethylene and polypropylene without the need for any release agent. For thick coatings GlassCast 50 can be poured directly onto dry surfaces such as metal, concrete and wood following a light ‘keying’ of the material.
*Additional layer should be poured when the previous layer reaches the B-stage of the cure. If the resin has fully cured the surface on the previous layer must be keyed to ensure a strong mechanical bond.
**Unlike most water clear resins, GlassCast can be cast into Condensation/tin cure RTV silicone rubber moulds without any problems.
