How do I choose the right resin system?

It depends on what you want to make (end use) and how you want to do it (application). You need to ask yourself the following questions:

  1. Room-temperature or heat-assisted cure?
  2. How thick will the resin layer be?
  3. What dimensions (volume or size) are you talking about?
  4. Do you care if it is transparent?

 

Do I need SuperSap CCR (clear casting resin) or SuperSap CLR (clear laminating resin)?

 This decision tree walks you through what we describe below:

1. How thick?

If you are casting a THICK layer of >3mm, then you need SuperSap CCR (Clear Casting Resin) as Part A – this ensures it won’t get cloudy with thick castings.

If you are casting a THIN layer of <3mm, then you can also use SuperSap CLR (Clear Laminating Resin) as Part A.

2. Choose the Hardener (Part B) as follows:

With SuperSap CCR (Part A), if you are casting a really thick layer >2.5cm, use the SLOW (CCS) hardener. This is to avoid exotherm on particularly thick casts.

If your layer is <2.5cm, then you can use the FAST (CCF) hardener.

With SuperSap CLR (Part A), you can choose between hardener speeds: CLX (Extra-fast hardener), CLF (Fast hardener) and CLS (slow hardener) depending on the amount of pot life (working time) you need.

 

What is the correct mix ratio of resin to hardener?

Most systems have a mix ratio by weight or volume. You can see it written in the labels, and in the TDS (Technical Data Sheet). For example:

SuperSap CCR

Mix ratio resin to hardener:

100:43 by weight or 2:1 by volume.

SuperSap CLR

Mix ratio resin to hardener:

100:47 by weight or 2:1 by volume.

SuperSap ONE

Mix ratio resin to hardener:

100:44 by weight or 2:1 by volume.

 

Are SuperSap resin systems biodegradable?

Not at this time. Biodegradable and non-toxic resins are still under development when you look at scientific articles on for example www.sciencedirect.com 

 

Are the resin systems 100% non-toxic?

Not at this time. There are chemicals inside because epoxy resin or any other polymer is a chemical. In order to prevent strong chemical smell we have kept the VOC volatile organic compounds as low as possible.
