WB4101 Compared to Competitive Binders Polymer Innovations, Inc. San Marcos, CA 92078 USA www.polymerinnovations.com Phone: 760-471-2504
Introduction • Standard two stage ball milling methods used • Choose some standard BME powder • Choose some nano powder • For PVB use standard Ferro 2 stage type.

TPL Nano BT • TPL nano BT • Dry powder • Some dispersion challenges for regular binders - agglomerates • WB4101 is strong dispersant and binder
TPL 150 nm BT WB vs. PVB PVB tape agglomerates are so bad tape is not usable and data is not representative
Dispersion Photo TPL 150 nm BT WB vs. PVB Both are 60 v/v% Powder and 2 stage ball milled PVB tape is unusable due to large agglomerates (45X)
Conclusions • Compared to PVB, emulsion and water soluble binders WB4101 typically results in higher packed density (green tape density) and easier lamination characteristics • WB4101 is superior for nano powders and can easily achieve well dispersed tapes with typical ceramic loadings. PVB did not. • WB4101 is capable of achieving high packing densities for thin <6 micron layers when other water based types can not.
