FR 6210 is a sulphonated melanin polycondensate, especially specific for cementitious materials such as Portland cement, lime, or plaster. FR 6210 is adsorbed on the surface of the particles, and by electrostatic charges (due to sulfonate groups), repulsive forces originate between them, dispersing the pastes, grouts, mortars, or concrete of cement, plaster, pigments, or forces.

FR 6031 is a sodium salt of condensed naphthalene sulfonic acid of high molecular weight. It is a powder easily dispersible in water that imparts excellent dispersion properties. FR 6031 works effectively in applications that involve the dispersion of particles of a solid in an aqueous medium or where it is necessary to reduce the viscosity of the dispersion. This property is due to the fact that the pH range in which this material is handled is very wide.
