QUICK RESULTS: OUR FAST-SETTING CASTING RESINS

duranity and duranity flex are our top products when it comes to casting climbing holds. But are you familiar with our quick-setting casting compounds? Our colleague and expert Gregor Franzen explains below which of your projects they are best suited for.

Gregor, why do we need the quick-setting casting compounds that we offer on our website under ‘Other accessories’?

We recommend two special quick-setting casting compounds that have different properties and are used for different projects. In any case, both are a good choice for climbing hold manufacturers.

Let's start with the SG 2000 quick-setting casting compound.

Gladly. We use this polyurethane casting resin to produce masters for the manufacture of silicone moulds. SG 2000 is very thin, which is great for accurately replicating the rough surface of the silicone mould. Due to its short pot life, the resin hardens very quickly. This master is so stable that it is suitable for many castings of silicone moulds, either as a solid casting or as a thin-walled silicone skin. With SG 2000, you can also make all kinds of impressions and use the filler F-B, for example: For each kilogram of A and B components, add up to four kilograms of filler. This reduces shrinkage, works well and is also inexpensive.

Okay, that sounds good. And what about SG 241?

SG 241 has a higher heat resistance, which makes it an excellent choice for manufacturing thermoforming tools.

What do I need those for?

Large volumes, macros, are now often produced by vacuum thermoforming – this is relatively inexpensive and also interesting in terms of sustainability, as the films for vacuum thermoforming can be made from recycled plastic. These thermoforming tools can be cast very easily from SG 241. Here, too, you can use up to four kilograms of filler for two kilograms of starting product – we recommend F-Alu from ebalta. The tool can then be cast solidly, but you can also use displacers. If the cast tool is then tempered, the temperature resistance increases, but this is not essential. SG 241 is really very easy to process – it couldn't be simpler.

If in doubt, you or Clemens are available to answer any questions, right?

Of course, you can contact us at any time and we will advise you on which of our materials is suitable for you and how to use it optimally.
