Many adhesives are not particularly environmentally friendly. Montana Biotech has been working on an affordable, water-based adhesive produced from a renewable resource. The high molecular weight polysaccharide is non-cytotoxic, biodegradable and has a melting point of 225 °C. This “green” adhesive has good tensile strength approximately 6.2 mPa on bare aluminum and is especially useful on epoxy glass and manufactured woods. Cured adhesive maintained full strength in an environmental chamber during a week-long 85% humidity, temperature-cycling program.
