When a leading adhesives manufacturer reached the limit of his plant capacity, he sent an S-O-S to his Humble representative. Our Research and Sales people suggested a new solvent. It would cost 16% more per gallon . . . but increase production up to 54% through greater solution viscosity at the doctor blade. Results: 1) Lower solvent cost per unit out­put. 2) Extra plant capacity with no new equipment. Bonus: fuel saving— the new blend evaporates with 25% less heat.
