BASF Tamol NN 9104

Famico Tamol NN 9104 cargoThe Tamol N types are very versatile stabilizers for aqueous dispersions and emulsions, and for aqueous solutions of surfactants and other auxiliaries. They can also be employed as grinding aids and dispersing agents for pigments and dyes in aqueous media, and as precipitants for basic dyes and cationic compounds. They may also be used as auxiliaries in metal finishing.All the Tamol N types have an excellent dispersing action and perform well as protective colloids. They are not surface-active, with the result that they have low wetting power and very little foaming effect.

The Tamol N types are condensation products of naphthalenesulfonic acid with formaldehyde. The various products differ from each other in terms of their degree of polycondensation, degree of neutralization, neutralizing agent and salt content.

The Tamol NN types have a low degree of polycondensation and Tamol NH 7519 has a high degree of polycondensation.

The products are identified further by the inclusion of a four-digit number in the product name. The first two digits indicate the typical active content and the last two digits the typical sodium sulfate content. The overall solids content is the sum of the active content and salt content. All the figures are approximate.

Early November Famico successfully exported Tamol NN 9104 to HongKong.
