【Feature of Ethyl Cellulose 】
Binder: Ethyl cellulose acts as a binder in conductive paste formulations, providing adhesion and cohesion to hold the conductive particles together.
Film-forming ability: Ethyl cellulose has excellent film-forming properties, allowing it to form a continuous film when dried or cured. This film helps to provide a stable and uniform coating over the conductive particles.
Solvent compatibility: Ethyl cellulose is soluble in various organic solvents, which allows for easy formulation and processing of conductive pastes. The solvents can be chosen based on their compatibility with ethyl cellulose and the other components of the paste.
Viscosity control: Ethyl cellulose can be used to control the viscosity of the conductive paste. By adjusting the concentration of ethyl cellulose, the viscosity can be tailored to achieve the desired application and printing characteristics.
Adhesion: Ethyl cellulose contributes to the adhesion between the conductive paste and the substrate. It helps in creating a strong bond between the conductive particles and the surface, ensuring good conductivity and reliability.
Thermal stability: Ethyl cellulose exhibits good thermal stability, which is essential for conductive paste applications that involve high-temperature processes such as sintering or curing.
Compatibility with other additives: Ethyl cellulose is generally compatible with other additives commonly used in conductive paste formulations, such as dispersants, rheology modifiers, and conductive fillers. This allows for easy incorporation and compatibility of different components in the paste formulation.
【Properties of Ethyl Cellulose uesed in conductive silver paste】
Ethyl cellulose is the ideal binder for conductive silver paste used in MLCC, due to its high purity, clean burn-out, adjustable rheological performance and outstanding batch-to-batch consistency
• Best performing ethyl cellulose with unique organo-solubility and outstanding stability due to advanced production process
• Good solubility and low impurities allows reduction of filtering costs
• Narrower and higher electrodes with sharper edges that contribute to high conversion rates for photovoltaic cells
• Formulation flexibility and reduced rheology adjustment costs
