Screen Printable Paste Inks, with Narrow Lines, Low Resistance and Clean Burn-Out

Lines of conductive paste ink, made from solvents, binders, metal powder, and glass frit, are screen-printed onto silicon wafers. The outstanding rheology of ETHOCEL™ allows screen-printing of tall, narrow electrodes with sharp edges.

Thanks to the high purity of ETHOCEL™ it burns off completely, leaving highly conductive electrodes required for high efficiency solar panels.

Our Solutions

ETHOCEL™ ethylcellulose polymers are being used as high-quality rheology modifiers, film formers, and binders in conductive inks for screen printing. Additionally, ETHOCEL™ ethylcellulose polymers act as wetting agents and lubricants during the three-roll milling to achieve the necessary fineness of grind (FOG).



Best performing ethyl cellulose with unique organo-solubility and outstanding solution stability due to advanced production process; Excellent solubility and low impurities allows reduction of filteri

Rheology modifier, dispersant, and sacrificial binder in conductive screen-printing inks

Your Applications

ETHOCEL™ ethylcellulose polymers are broadly used as high-purity rheology modifiers for photovoltaic frontside and backside metallization pastes.
