TER AS Productos was founded in Barcelona in 2009 with the objective to strengthen the position of TER GROUP in the Spanish market. During the last years we have grown constantly gaining an important position in the different sectors our customers are part of.



Our dispersants are additives that allow or stabilize the dispersion, i.e. the optimum mixing, of at least two normally immiscible phases (substances) . Dispersants (surfactants) reduce the interfacial tension between a solid surface and a liquid and thus promote wetting.


Dispersants are used for cement-based and hydrated lime-based dry mortar in the construction industry. Dispersants can also be used for every application in which solid and liquid components form a stable suspension. The main application areas of our dispersant are the coatings and rubber industry.
