Cray Valley, EXTON, Pa., 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 nonpolar 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, and may also be used as additives in other water-based formulations such as adhesives, coatings, paper sizing, construction materials and composites.
