MOLTOPREN® – coloring of PU foams

Color pastes for coloring polyurethane systems based on polyether and polyester

The applications of MOLTOPREN® pastes are very varied. In the polyurethane industry, they are especially recommended for the universal coloring of PU foam or slabstock foam (ester and ether) and are used for the technical labeling of foams.

Our pigment pastes of the MOLTOPREN® range are based on a special carrier binder. They are precisely tailored to the requirements of combined use in polyether and polyester systems.

MOLTOPREN® pigment pastes are manufactured as monopigment pastes within narrow tolerances in terms of color strength and color location. Of course, you can also get already mixed shades according to your individual requirements.
