Formulation Additives for reactive systems

Dispersing Agents

Grinding and dispersing of pigments and fillers is one of the most difficult and

time / energy consuming part of the production of coatings and other reactive

systems. The use of dispersing agents during this process is indispensable and

ensures better wetting of the particles, reduces viscosity and prolongs stabilization.

It also helps improve color strength in coatings.

BASF’s broad technology portfolio including polymeric, oligomeric and surfactant

based dispersing agents enable our customers to find optimum solutions for their

reactive resin formulations.

Defoamers

Defoamers are essential components to control and prevent

foaming during formulation, application and transport of

reactive resins.

Foam is an extremely undesirable phenomenon that can

reduce the efficiency of the production process, impact

the surface appearance and promote weak points in the

dried film.

A defoamer point of action is the stabilized foam lamella.

Therefore, the product should be insoluble in the system and

able to enter the lamella and develop the defoaming action.

Depending on the formulation and customers’ requirements

different products can be selected to ensure the perfect

balance between performance and compatibility.

Efka® PB and Efka® SI range for reactive systems are based on

raw materials with low surface tension such as polysiloxanes,

polyacrylates and other organic polymers.

Rheology Modifiers

Rheology modifiers are key ingredients to control viscosity,

consistency and sag resistance in reactive systems. The

special additives enable the formulators to adjust rheology

and flow in their systems and improve the application char-

acteristics of the formulations.

To control rheology in reactive systems, we recommend

powder grades such as hydrogenated castor oil powders –

Efka® RM and hydrated magnesium aluminosilicate – Attagel®.

These additives offer high thixotropy and sag resistance.

Film-forming agents

Within the category of film-forming agents we present three plasticizers for reac-

tive systems focusing on low-VOC products. Plasticizers enhance the flexibility of

the final film after completion of the cross-linking reaction. But depending on the

application they are also used to enhance adhesion and tackiness or the rheologi-

cal behavior of a reactive system.

Wetting Agents and Surface ModifiersA smooth appearance in coatings systems depends on

good flow and leveling. Wetting agents and surface modifiers

enhance the component compatibility in the system and

provide the formulation with an adequate surface appearance.

BASF Performance and Formulation Additives offers a broad

portfolio of wetting agents and surface modifiers for reactive

systems based on various chemistries. Besides the Efka® tech-

nologies presented here we also recommend Loxanol® MI 6721,

which acts as an adhesion promoter and a cross-linking com-

ponent in epoxy or PU systems.
