Polyester Special Water Clear Casting Resin (arts etc) and Catalyst

  • UV stable
  • Excellent for preserving and embedding decorative objects
  • Super clear once cured
  • Suitable for outdoor use

Please note, due to the styrene content in this Resin, it does have a strong odour. It should be used and stored in a well-ventilated area.

How to Calculate your Volume of Resin

Multiply height (in metres) x width (in metres) x depth (in millimetres).

e.g. Require coverage for a table - 1 metre high x 2 metres wide x 5mm depth = 10 litres/kg of resin. 

Further application details can be found on our Clear Casting Resin instruction guidelines.

Product Description

This water clear casting resin is used for embedding and preserving biological and medical specimens. It can also be used for making paperweights and decorative objects, such as costume jewellery. 

Because of its water-white appearance when cured it can be used to create water effects such as streams or waterfalls by modellers. Catalyst addition is 1.5% giving a pot life of approx. 20 minutes.

It is important to leave the resin piece in one place for 4-5 days after pouring so the resin to allow it to cure effectively.

This resin is UV stabilised, meaning it can be used for outdoor use and projects which will be kept in the garden e.g. pebble displays or waterfalls.

If doing multiple pours of clear casting resin, great care should be taken in regards to the heat that is generated with each pour. Before each pour, it is best to ensure the first pour has cooled (and is cool to the touch) before adding the next batch of resin.

We also stock a Clear Epoxy resin too. This is also available to purchase on our website.

Ask a Question

Work out how much Glass you have by weight and multiply by 2.5. i.e. for 2kg of fibreglass mat, you will require 5kg of resin. Alternatively, use our Materials Quantity Calculator. Roofing applications may require more resin if the resin is applied to OSB3 boards as the boards will soak more resin. Our materials calculator will give exact requirements depending on application e.g. Roofing, Pond Lining or General Fibreglass Projects.

Yes, all Resins, Topcoats and Gelcoats sold by FibreGlassDirect are supplied with sufficient catalyst. 

We recommend that up to 10mm of Clear Resin should be poured at any one time before pouring the next layer. If doing multiple pours of clear casting resin, great care should be taken in regards to the heat that is generated with each pour. Before each pour, it is best to ensure the first pour has cooled (and is cool to the touch) before adding the next batch of resin.

Yes, the Polyester Clear Casting odour has a strong, solvent odour. Therefore, this resin is best used in a well, ventilated area.

Yes, the Water Clear Casting Polyester Resin may be used for making Canvas Micarta (knife handle). Once the resin has adequately cured it can be shaped as required.

The Clear Casting Resin will not cure in a uniformed fashion. It will be tacky to the touch with ripples. To remove the tackiness of the cured Clear Casting Resin, you must sand back the top layer starting with a 240 grit sandpaper, working up through 400 to 600 until all bumps or ripples have been removed and the area is totally smooth. To get a shine, use a Farecla Compounding Paste.

Yes, this resin is suitable for use with a silicone mould. If there is a lot of detail in the mould, you could use a CIL release spray if required before pouring the resin into the mould.

No, unfortunately, this resin would not have enough scuff or scratch resistance to be used on a floor.

Yes, this Resin may be used for casting penneys onto a table. If using a glass table, great care should be taken with regards to the heat which is generated during the curing process to avoid any cracks in the glass. We recommend several pours, ensuring the previous pour is cool to the touch before adding the next pour. The resin will cure tacky, so once cured the top layer will need to be sanded back and compound paste used for shine. A clear lacquer may also be used to prevent scuffs and scratches. We have made a video detailing the process and it is available to watch on our... Read more

Unfortunately, Polyester Resin cannot be used on Polystyrene as it will eat into it! An Epoxy Resin would be better suited for this application.
The shelf life of Catalyst is approximately 6 months. It is important that the catalyst is stored in its original packaging in a cool, dry location away from sunlight. As Catalyst is an extremely flammable chemical, it is important to refer to MSDS and TDS sheets before use.

There is a simple formula for calculating the volume for resin required. Simply multiply length (metres) x width (metres) x depth (millimetres). 

In this case - 1.5 metres x 1.5 metres x 5mm = 11.25kg of resin. This method will work for epoxy and polyester calculations.

For river resin tables we would recommend our clear cast epoxy resin as this will be more durable and will have less shrinkage than the polyester version.

This depends on the temperature of your working conditions and how much catalyst has been incorporated into the mix. Warmer temperatures will reduce your curing time and colder temperatures will increase the length of cure.  Likewise, adding extra catalyst will speed up the curing process - often necessary for colder temperatures and reducing catalyst will reduce curing - again often necessary during warmer temperatures. We would recommend mixing no more than 1.5 - 2kg at a time. Once the resin and catalyst are mixed, the curing process will begin and you are working against the clock to get the resin applied - usually no more than 20 minutes. Only mix as much as you need.  Epoxy Resin is mixed on a ratio basis and should not be altered. Room temperature is the ideal scenario for curing. Each resin type will differ so we would always recommend referring to the MSDS and TDS available on each product listing before use.  Although some resins may be hard to the touch after 24 hours, some may not be fully cured for up to 3 days. Again, this information will be available on the product Technical Data Sheet... Read more
Generally speaking, for Polyester Resins, the mixing ratio is 2% i.e. 20ml for every 1kg of Resin in working conditions at room temperature. For the Water Clear Casting Polyester Resin, this drops to 1.5% or 15ml for every 1kg. In colder working temperatures you may wish to increase the catalyst addition to 3% but definitely, no more than 4% to speed up the curing process. Similarly, in warmer temperatures, you may wish to reduce the amount of catalyst to extend the pot life of your resin. In this case, you should not go below 1%.  To ensure accuracy, please refer to the TDS of each resin which will detail cure times.  Epoxy resins are treated very differently and work on a ratio e.g. 1:1. Please refer to the TDS and MSDS attachments which are available on each product page as each Epoxy Resin will vary. If in doubt, don't hesitate to contact our team who would be happy to... Read more
