BASF Multicolor Solution

-- A 100% water borne coating

BASF Multicolor Solution is a W/W system base

on Acrylic binder

It is a pair of two water borne acrylic

dispersions giving the full system for

multicolored coating.

The cured film is extremely durable and may

be washed repeatedly without causing

damage.

Colored particles

Continuous phase

Multicolor: Application and Paint itself

It is a water in water emulsion (gel) that remains

like a paint

Spray on wall

7

Basically, the colored particles

(pigments) are ‘capsules’ with

tinted coatings sealed inside.

The size is varies from 0.5mm to

several millimeters.

And continuous phase is a kind of clear paint. A transparent film will be

formed after it dried

Acronal® 7077

A binder for base paints which will yield color capsules after

react with Acronal® 7099. It is an acrylic emulsion with

moderate flexibility.

Acronal® 7099

A binder for continuous phase, which will react with base paint

(Acronal® 7077) and get color particles. And it is the carrier for

color particles, which will form a clear film

Additives

BASF offer various additives for the system such as Dispex®,

Rheovis® thickener, Foamaster®/Foamstar® etc.

Colorants

BASF Luconyl® colorants are also be recommended.
