Without producing clumps, a professional adhesive must be poured in a consistent and smooth way. A company seeks a dispenser/ applicator that can handle a thick, gelatinous, preformed, professional-quality adhesive. Currently, a polymer dispersion of polyvinyl pyrrolidone is used. While the stearates thicken the adhesive and provide an even “flow,” they bring the compression/shear strength of the formulation down to 400-600 lbs. A proposed professional-level adhesive must dispense just as well, but offer a compression shear strength of 2000-2500 lbs. The substrates to be joined include such porous substrates as wood and engineered wood products, and various non-porous surfaces such as metal and plastic.
