Binder waterbased

WB4101

Most popular water based binder with basic defoamer, wetting agents and other additives. In general will outperform popular solvent based systems. Binder also acts as ceramic dispersant and therefore typically 25-50% of the total binder should be included in the grinding stage. WB4101 is 35% solids (28% polymer and 7% plasticizer). For more specific tape casting guidelines PII can be contacted for example formulas for certain ceramic types and there are several other resources such as the presentation called “Tape Formulation”, the demonstration kit and custom formulation services are also available.

WB40B-67

Similar to above (same polymer type) but with none of the plasticizer used in the WB4101.

It is useful for making stiffer and harder tapes. Binder solids are 27% (27% polymer and 0% plasticizer).
