Whats the difference between a hard coat and a soft coat?
A hard coat is a pyrolytic coating applied on-line during the initial glass manufacturing process. Since the coating is applied while the glass is in the semi-molten state, it becomes part of the glass surface. A soft coat is a sputtered process that is applied in a batch method after the initial glass manufacturing. The sputter coating is not integral to the glass surface, but rather is a surface coating. There are advantages and disadvantages to both coating options. Please contact Pilkington Product Specialist for more information. For more information on pyrolytic coatings, see The Pyrolytic Advantage.
