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.

� Slip characteristic
� Slip angle° is reached until a sled of
specified weight moves along the
coating`s surface.

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
