Resin Casting For Slower Art Casting 

Casting Moulds using casting resin can be a complicated process. Pouring resin into a mould can be one of the more challenging things. When pouring, if you pour it too fast or too high, it may contain a lot of bubbles during the final cure. To avoid this, you can use our ArtCast casting resin as it’s very low in viscosity coupled with outstanding air release, which will provide higher quality castings with minimal to no bubbles.

What is an Epoxy Casting Resin?

Epoxy casting resin is of a less viscous consistency than normal epoxy coating resin. An epoxy casting resin is made explicitly for casting works, such as moulds, figurines, filling wood, deep pour, and jewellery. Unlike most coating resins, a casting resin normally takes a longer time to cure and can take up to one week for demoulding. The low viscosity resin systems enable the resin to flow into and occupy the smallest of gaps and cavities. Casting resin will normally cure a lot harder than coating resin systems.

To use casting resin kits, you will need to mix part a being the resin with part b the hardener. The proportion of hardener to resin will differ with the sort of resin you are utilising see our resin calculator for further details on proportions. The mixture will start to cure and harden after a specified period of time once mixed. 

Once cured, casting resin can be polished or sanded to create a smooth, hard and glossy finish. 

Why Should I Use A Slow Curing Casting Epoxy Resin?

With very slow curing casting systems, demoulding can take up to 7 days and up to 14 days until the cured resin is hard enough to sand and polish. Normally Slow casting epoxy resin systems are designed for very large projects such as River Tables or large volume castings (over 3 litres). Therefore, curing times may be enormous when casting smaller items. ArtCast is geared towards smaller casting that requires ultra-toughness against day to day wear and tear. It is ideal when it comes to more complicated designs such as keychains or keyrings to pyramid moulds.

Resin Casting Troubleshooting Tips and FAQs

If you're having trouble with Casting Resin or the Art Casting Process, here are some troubleshooting tips and FAQs that may help.

Why is there wet/ uncured resin on the bottom of my casting?

A: When measuring Casting Resin, if you find the casting is curing hard but has wet tacky spots usually on bottom, this is the outcome of not enough hardener.

Why is my casting soft & malleable after cured?

A: When measuring Casting Resin, if you find once resin is cured, the resin is still soft and malleable, this is the outcome of having too much hardener.

What could be the causes of Resin becoming hard in the cup?

A: 1. Over 10 percent ink/pigment/acrylic paint to Resin ratio by weight was used *It is important to note that not all acrylic paints or pigment additives are compatible and some will catalyze the curing process since they contain high levels of water.

A: 2. Excess Part B, measuring is to be accurate

A: 3. Room temperature too high, should be 22-25 degrees

A: 4. Mixed Resin should not be left in a confined area (e.g. cup, jug) as this will speed up the curing time and may experience violent exothermic reactions.

My resin is not curing. What is wrong?

A: This can occasionally occur due to incorrect mixing of the resin and hardener together a small trick is to pour Part B (Hardener) first then add Part A (Resin) this to help the resin not to stick to the sides of the container or jug. Stir until Resin and Hardener are clear and without streaks, do not forget to scrape the sides and stick.

What are the bubbles in my cast?

A: Bubbles may be caused by several reasons. The first reason could be that you mixed the resin and hardener excessively before you poured them in the mould. 

A: The other thing that could happen is that your piece is too thick and this can cause pockets of air to become trapped within it as it dries, this can happen more in cooler weather.

What causes bubbles on the outer edge of my casting?

A: Occasionally some moulds may entrap air bubbles on the wall, this may be caused by a rough mould surface sometimes found when using DIY moulds, or in very small high detail moulds. A small secret is to run a mixing stick or brush over all the surfaces of the mould, this will aid the release of air bubbles.

My mould is not coming off the resin - What should I do?

A:To avoid this there are a couple of things you can do. First is to ensure that you apply mould release agent on your mould before you pour in the resin. It may also be that the resin has not fully cured and may still be soft, in which case it has more time before de-moulding.
