high performance PE base coating
Polyester is the most recent material to be used on pianos. It is a product of modern chemical technology that provides the highest degree of beauty and protection available. Polyester is a very stable product and weather changes have no effect on its size. Therefore, applying a stable finish to a constantly changing surface invites trouble. When the wood changes in response to humidity, the polyester can crack or lose adhesion with the wood.YAMAHA utilizes a special resin and wood pulp formula to create a sheet of material that provides a stable surface for the polyester application.
