The new dispersion PRIMIS^® SAF 9000 ensures permanently clean walls, as can be seen by a direct comparison – while the left-hand surface was painted with a conventional interior paint, the right-hand surface has been treated with a paint containing PRIMIS^® SAF 9000: Even lipstick can be completely removed from the treated wall (right bottom), while the untreated surface still shows visible stains after cleaning (left bottom).
