Applications

ETHOCEL™ Standard 4 Industrial is multi-functional resin. It works as a binder, thickener, rheology modifier, film former, and water barrier in many applications as detailed below:

  • Adhesives: ETHOCEL™ Standard 4 is broadly used in hot melts and other solvent-based adhesives for its excellent thermoplasticity and green strength. It is soluble in hot polymers, plasticizers, and oils.

  • Ceramics: ETHOCEL™ Standard 4 is highly utilized in ceramics made for electronic applications such as multi-layer ceramic capacitors (MLCC). It works as a binder and rheology modifier. It also provides green strength and burns out without residue.

  • Printing Inks: ETHOCEL™ Standard 4 is used in solvent-based ink systems such as gravure, flexographic and screen printing inks. It is organosoluble and highly compatible with plasticizers and polymers. It provides improved rheology and binding properties which helps the formation of high strength and resistance films.

  • Coatings: ETHOCEL™ Standard 4 provides waterproofing, toughness, flexibility and high gloss to paints and coatings. It can also be used in some specialty coatings such as in food contact paper, fluorescent lighting, roofing, enameling, lacquers, varnishes, and marine coatings.

  • Other Applications: ETHOCEL™ Standard 4 uses extends to other applications such as cleaners, flexible packaging, lubricants, and any other solvent-based systems.

ETHOCEL™ Versatile and Performance-Enhancing

ETHOCEL™ ethylcellulose polymers are organosoluble products with a narrow specification and uniform ethoxyl functionality. This enables ETHOCEL™ to have very predictable performance, key to industrial applications where the same output is desired batch to batch.

ETHOCEL™ polymers are water-insoluble thermoplastic polymers; they can therefore be employed for a wide variety of functions. They are used for rheology modification, film formation, binding, water barriers, and as time-release agents. ETHOCEL™ can also be effectively used as a sacrificial binder as they exhibit clean burn out.
