Press Release Summary:

January 21, 2014 - Dispersed in water, Ricobond® 7002 and 7004 produce low-viscosity, stable dispersions with small particle size. Both can be formulated with other emulsions for optimized adhesion to different polar and non-polar substrates. Adding dispersions to standard latexes such as SBR and VP emulsions can also improve water resistance and mechanical properties. Other uses include water-based adhesives, coatings, paper sizing, construction materials, and composites.

Cray Valley Introduces Ricobond® 7002 and Ricobond® 7004

Press release date: January 10, 2014

EXTON, Pa. — Cray Valley has launched Ricobond® 7002 and 7004, two aqueous dispersions of functionalized low molecular weight polymers. The polymers are dispersed in water to produce low viscosity, stable dispersions with small particle size. They can be formulated with other emulsions for improved adhesion to different polar and non-polar substrates.

Ricobond® 7002 and 7004 have demonstrated excellent performance in textile (fabric and single-end cord) to rubber adhesion as well as adhesion to other substrates such as metal and PET film.

Ricobond® 7002 has shown utility in filler treatment to improve dispersibility and overall properties of the thermoplastic resin.

Adding these dispersions to standard latexes such as SBR and VP emulsions can improve adhesion, water-resistance and mechanical properties. Ricobond® 7002 and 7004 may also be used as additives in other water-based formulations such as adhesives, coatings, paper sizing, construction materials and composites.
