Sap Stain

The microbial discoloration of sap wood, commonly called “sap stain”, results in the total loss or depreciation in value of large volumes of lumber each year. Because of the ever growing value of lumber and the need for efficient utilization of wood, saving and using the sap wood of trees is very important.

Products from the LANXESS portfolio are a reliable solution to this problem. Treatment of freshly sawn logs with a biocide formulation is very effective at preventing discoloration, thereby extending storage time and increasing overall quality.
