Bermodol

Bermodol additives are polyurethane- or surfactants-based and can be used  to modify rheological properties in paint and aid in dispersing pigments.

Bermodol PUR
The Bermodol PUR range of polyurethane-based associative thickeners –  Bermodol PUR 2102, 2110, 2130 and 2150  –  has been developed to enable paint manufacturers to formulate their paints to suit market preferences on viscosity, brushing resistance, hiding power, levelling, consistency and spatter-free application.

Since they are associative thickeners, they are highly dependent on their interactions with other ingredients in the formula, including binders, surfactants, dispersants and pigment particles. Their hydrophobic groups interact with other hydrophobic groups or with surfaces resulting from components present in the paint. They also interact with one another, contributing to an increase in viscosity.

The main difference between the products lies in how much they associate with other hydrophobic components. Bermodol PUR2102 and 2150 display the strongest associations. Bermodol PUR 2110 and 2130 displays the weakest association. Their differing associative performances lead to different rheological behavior, enabling them to be employed to obtain different end-results in paint formulations.

Bermodol SPS
Universal colorants are liquid dispersions of solid pigments, and these color pastes should be compatible in both water borne and solvent borne paints. The dispersing process is a very important step in the manufacturing of pigment pastes, and to achieve the right tinting strength when add it into the white base paint, the choice of wetting and dispersing agents is critical.

The Bermodol SPS range consist of optimized nonionic surfactants, with very good wetting and dispersing properties for organic pigments, in water borne colorants.

These Bermodol SPS products are all free of alkyl phenol ethoxylates and organic solvents.
