HANSA® ADD 6775 – THE CHEMISTRY BEHIND

15.01.2019 Technology Management, BU Paints & Coatings3

HANSA® ADD 6775 is based on a modified, high viscosity polydimethylsiloxane emulsion.

Due to its nonpolar character and its low surface tension, migration to the coating surface takes place. Here, slip & anti-blocking properties come into full effect.

HANSA® ADD 6775 – TEST METHODS

15.01.2019 Technology Management, BU Paints & Coatings6

� Slip characteristic

� Slip angle° is reached until a sled of

specified weight moves along the

coating`s surface.

Slip angle°

Horizontal movement

� Abrasion Resistance

� Evaluation of surface gloss reduction

∆GU caused by friction of a coated

weight that moves horizontally.

As lower the slip angle°, as higher the slip of a surface Gloss reduction ∆GU in % after 200 double strokes
