- Based on metal salts of 2-ethylhexanoic acid (octoates) or their isomers
- Accelerates film structure and cute of resin binders
- Used in conjunction with organic peroxides to cure unsaturated polyester systems
- Unsaturated polyester systems for coatings and casting resins
- Synthetic resins for fiber reinforced tools
In unsaturated polyesters, the addition of cobalt is between 0.005 and 0.020 %, calculated as metal on solid
binder. Octa-Soligen® Cobalt accelerators can be used in combination with 15% Potassium Hex-Cem® EU and Borchers® Deca Copper 8. 15% Potassium Hex-Cem® EU helps to reduce discoloration of the resin binder that results from the cobalt. This is obtained due to a reduction of the cobalt which overlays the natural cobalt color shade. In combination with Borchers® Deca Copper 8, pot life can be controlled. In addition, the curing process will proceed with less thermal development. This is important to prevent surface imperfections, cracks and discoloration, particularly in case of bigger tools. Irrespective of these guidelines, the addition should always be determined in preliminary trials.
Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product.
