Application
OPTAPIX C types differ by their degrees of polymerization and hence the viscosities of their aqueous solutions.
OPTAPIX C types are used in glazes and engobes as viscosity adjusting, non-foaming binding agents. They improve the abrasion resistance, give glazes or engobes a good fit and prevent running.
Sodium CMC being a polyelectrolyte, the low viscosity, i.e. short-chain types like OPTAPIX C 12 G / C 25 G, have a deflocculating effect besides their binding property.
As far as the sodium CMC types with a medium degree of polymerization, such as OPTAPIX C 50 G, are concerned their electrolytic effect is to a large extent compensated by their increased intrinsic viscosity; they, therefore, have a rather neutral effect on the viscosity of the glaze slip, at the usual addition quantities.
High polymer types such as OPTAPIX C 200 G / C 1000 G have a thickening effect on the glaze
