Frequently Asked Questions

What happens to resin if it has passed its shelf life?

When a product has exceeded its shelf life, the casting process can become unstable. Working time and demolding time will likely change as well.

Does temperature play a role in the casting process?

Temperature plays a major role when it comes to mixing and curing silicone, resin or epoxy. Heat and humidity can speed up your curing time and cooler temperatures will do the opposite and slow down your curing time.

How much metallic or glow-in-the-dark powder am I supposed to use in my resin or epoxy project?

When adding metallic or glow-in-the-dark powder to your resin, you should start by adding small amounts and continue to add more until you reach the desired result.

What is the right amount of pigment to use?

When adding pigment to a project remember a little goes a long way. Add pigment by drops until you reach the desired color. Make sure to make a note of how much pigment you used so you can match if making multiple batches.

How do I eliminate bubbles in my silicone mold?

There are few ways you can eliminate bubbles in your silicone rubber mold:

  • Degas material within the working time frame.
  • Pour a thin stream and allow material to slowly fill in any negative space.
  • Use a thinning agent that will allow bubbles to rise faster.

Works well, demolds well, no issues

Works well, no problems with curing or demolding... seems a a little softer than 40. I'll try the 60

Issues with wrong information and short shelf life

I had a lot of issues with your AI response system and information in the website being wrong about suggested glues paint etc. I nearly lost a client because nothing was working. Costing me a 3000$ commission as well the hardener agent went bad despite being dept climate controlled and closed other than initial pouring.
