BENEFITS OF ZONYL® TREATMENT
•抗沾污 STAIN RESISTANCE •抗油 OIL REPELLENCY •抗油渍、抗尘污 GREASE AND DIRT RESISTANCE •易清理 EASIER TO CLEAN •抗水 WATER REPELLENCY •天然观、触质感 NATURAL APPEARANCE •无形防护 INVISIBLE TREATMENT •非覆膜型 NON-FILM FORMING •高透气性 PERMEABLE TO WATER VAPOR
石材种类 石材
Types of Stone
• 有些石材含有 (CaCO3)
• Some stone contains calcium carbonate (CaCO3)
例如，大理石，石灰石，石灰华
e.g. Marble, Limestone, Travertine
此类石材较易受酸蚀，对表面磨光之大理石则会 因酸蚀而失去光泽
