Plywood Makers Look At Soy

Pacific Adhesives Co., Portland, Or., is testing a new, soy-based plywood glue in pilot programs to replace animal blood protein currently used in plywood glue formulas.

These tests are an intermediate stage between the National Center for Agricultural Utilization Research, Peoria, Illinois, and mill trials, which use the actual volume of glue required for one day's work.

"Concerns about animal blood's limited supply and health issues prompted our search for alternative protein extenders," said Milagros Hojilla-Evangelista, a research associate in the Plant Polymer Research Unit at ARS.

The plywood glues were designed to be applied by "foam extrusion," which is one of four conventional ways the industry applies glue to wood. The extenders are substances added to an adhesive to reduce the amount of resin required.

As part of their evaluations, Hojilla-Evangelista and ARS technician Rick Haig checked each experimental formulation for its foaming ability, refoaming ability, foam strand quality, and adhesive properties.

"Early results have confirmed our laboratory findings about foaming properties and adhesive quality," said Hojilla-Evangelista.

NCAUR researchers tested three different soy glue formulations by varying the amount of soy extenderadding either soy flour, or soy concentrate.

Soy flour has been found to make the best glue, and the glue ends up being 50 cents less expensive per 100 kilograms than conventional formulations. Flour makes up 3.5Vo to 5.5Vo of the glue mix, with the adhesive resin being the primary component.

Researchers found that soy flour cannot be used one-for-one in place of blood protein in glue because soY flour contains less protein than animal blood. Increasing the amount of soy flour produced glue that foamed better at less cost.

"We have to get the amount of soY just right to produce a glue that will foam as well as conventional glue, and at the same time be as adhesive," said Hojilla-Evangelista. "Other benefits of our foamed soy-based glue are that it requires less drying time, uses less water and produces less waste than conventional plywood glues."

The new glue could create an additional domestic market for nearlY 50,000 bushels of soybeans annually.

Eleven plywood mills in North America currently use foam extrusion technology: two each in Louisiana and Washington and one each in Idaho, Oregon, Montana, Arkansas, Mississippi, Texas, and British Columbia.

The latest foam extrusion system reportedly was installed last year in Hamina, Finland, and is the first plywood mill in that country to convert to foam extrusion application because of Finland's new pollution regulations.
