We have a wide range of aqueous solutions of organic dyes that are designed specifically for addition to particle board resin binder systems and in dilute form to MDF fiber mats for identification purposes. Our dyes are stable in both the high temperature and acidic environment encountered in board pressing operations. They have no detrimental effect on board properties. Also, because they are UV stable, our dyes are widely used in laminates such as High Pressure Compact Laminates.
