GlassCast 50 has been designed as a casting resin, not a coating resin. This means that whilst it offers the advantage of incredible clarity - even in thick sections - it does not cure with a perfect surface on the open face in the way that our GlassCast 3 coating resin does. However, GlassCast 50 can easily be flatted and polished to achieve a perfectly flat, glossy finish if required (such as the top surface of a river table).

Suggested Uses

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.

Suggested Uses

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.

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.

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.

Shelf Life

Shelf Life is 12 months from date manufacture. GlassCast should be stored in its original container and out of direct sunlight. It is recommended that the storage temperature should be between 15ºC and 25ºC. Ideally, containers should be opened only immediately prior to use. KEEP THE PACKING TIGHTLY SEALED WHEN NOT IN USE. When stored correctly, the resin and hardener will have a shelf-life of 12 months. Although it may be possible to use the resin and hardener after a longer period, a deterioration in the performance of the resin will occur.

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.

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.
