ETHOCEL™ Standard 4 Industrial is a low molecular weight, water-insoluble, ethyl cellulose polymer that is used as a binder in specialty inks and coatings.
ETHOCEL™ Standard 4 Industrial is the lowest molecular weight ethyl cellulose polymer available from DuPont. It is very high purity, burns out cleanly, and is excellent for improving the green strength of conductive pastes used to screen print circuits for photovoltaic cells. ETHOCEL™ Standard 4 Industrial is soluble in many common solvent types including esters, ethers, ketones, aromatics, and alcohols. It is used to impart a pseudoplastic rheology to solvent based coating, ink, and adhesive formulations. Additionally, ETHOCEL™ Standard 4 Industrial is thermoplastic and can be used to form durable films with excellent gloss and flexibility. ETHOCEL™ Standard 4 Industrial is soluble in many solvents commonly used in gravure ink formulations and can be easily added to improve the properties of the ink. In gravure ink formulations, ETHOCEL™ Standard 4 Industrial is used as a rheology modifier, pigment binder, and improves printability on difficult substrates like plastic and glass.
