. Advancing knowledge of forests and rangelands : 1984 research accomplishments. Wood Research United States Bibliography; Forests and forestry Research United States Bibliography; Forest fires Research United States; Insect pests Research United States; Forest management Bibliography. Products and Engineering Adhesives From Southern Pine Bark Scientists at the Southern Forest Experi- ment Station, in cooperation with private industry, have developed a process that enables two-thirds of the resorcinol used in cold-setting adhesives to be replaced by tannins from southern pine barks. Resorcinol is an expensive phenolic com- pound derived from petroleum. The use. of tannins, which are a renewable forest resource, reduces both the cost of these adhesives and also the dependence of industry on petrochemicals. Cur- rently pine bark is primarily used for fuel at the mill, but after the tannins are extracted, about 80 percent of the bark weight can still be recovered for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
