from 1939 through 1942.<br />

As will be seen, the major portion of <strong>formaldehyde</strong> u-as consumed by the<br />

synthetic-resin industry. Uses in this field include not only the preparation<br />

of cast and molded resins but also production of resin adhesives for<br />

plywood and other laminated products, manufacture of resin lacquers,<br />
