The fillers should be stirred into the single components A and B , so that these have nearly the same viscosity. After that both components can be very well mixed. In case of small quantities and sufficient experience it is also possible to mix the unfilled components first and then to stir in the filler, without making the potlife too short for casting.

Technical Details & Test Data
- In General
We have different resins -with one hardener- available. The various types differ in potlife and curing time:
- SG 2000 S, potlife 1,5 – 2,5 minutes
- SG 2000, potlife 2,5 – 3,5 minutes
- SG 2000 L, potlife 7 – 8 minutes
- SG 2015 potlife 14 - 18 minutes
The fast curing of the materials leads to a short demoulding time. The very thin binding agent effects a high filler content. The addition of different fillers determines the properties and strength.
Material should be carefully stirred up/ shaked before use. The product can be subject to color variations due to raw materials, but these color variations have no influence on the quality and the properties of the product.
