摘要:
An engineered wood based siding, cladding or panel with a pre-consolidated fines layer (PCF) applied to the top of the main strand matrix layers to minimize telegraphing and provide an improved surface appearance. The PCF is consolidated prior to application to the surface of the strand matrix or mat, and takes the place of a loose fines layer. The PCF prevents the loss of fines into the strand matrix, effectively keeping the fines at the surface so they can effectively and efficiently function to prevent or eliminate strand telegraphing, and provide a smooth finished surface for the product.
