Abstract

A material adapted for use as a binder in moulding compositions is prepared by incorporating water or furfurol in substantially pure and ash-free lignin material derived from spent digestion liquor to lower the melting point below the melting point of the over-dry material. In examples, the incorporation of 12 per cent of moisture in a material having a dry melting point of 203 DEG C., lowered the melting point to 125 DEG C., and the incorporation of 13,4 per cent of moisture into a material having a dry melting point of 148 DEG C., lowered the melting point to 72 DEG C. The treated material may be incorporated with fillers such as wood flour, cotton linters reclaimed tyre fabric, or asbestos, alone or in combination with other binders such as phenol-aldehyde and urea-aldehyde resins, shellac, casein, cellulose acetate, &c. A suitable composition comprises 50 per cent filler, 25 per cent synthetic resin and 25 per cent the treated lignin material.
