HEIITLOCK EXTRACT SUCCESST'UL rN COII)-SETTING LIIMINATES

Montreal, P.Q., Canada, June ?-An extract of western hemlock bark can be used to obtain spectacular results in cold-setting adhesives at new, low-costs, members of the Forest Products Research Society heard here today at the Society's 14th annual meeting'. Dr. X'. W. Herrick, a scientist from Rayonier's Olympic Research division at Shelton, Washington, reported that the chemical cellulose producer's relatively new silvichemical, HT-120, a unique and highly reactive polyphenolic intermediate, can be used successfully as a partial replacement for expensive resorcinol.

The report revealed that adhesives containing from 30 to 60% of the bark product on a solids basis gave excellent bonding quality in Douglas fir laminates prepared under room-temperature setting conditions. The new adhesive bonds were found to be fully resistent to delamination by water during several Cycles of vacuum-pressure treatment followed by drying or by prolonged boiling water treatment. Dr. Her- rick said these new adhesives were developed to meet pot-life and long open assembly requirements of the softwood laminating industry.

He added that it is possible to modify or tailor-make adhesives of this type to fit the operational requirements of industry.,.Util- ization of this natural, forest-grown resource permits a reduction in adhesive costs and at the same time contributes to the upgrading of our basic forest resource -wood," he said.

In. 1958, Dr. Herrick disclosed that Ray- onier's tree bark extract met ,,all present commercial requirements" for exterior type plywood, noting that the intermediate can help cut costs in ply"wood production and expand markets for plywood in outdoor construction.
