Ready! 4 chemical derivatives from Starch FREE RESEARCH KIT The best place to keep abreast of new developments in chemical derivatives from starch is right in your own experimental laboratory. Try applying the widely varying characteristics of NATIONAL'S four basic chemical derivatives and a new type of starch to your current problems. 1 —DRY FLO—-a starch ester derivative containing hydrophobic groups. Excellent flow . . yet cannot be wetted with water. Will produce films with water repellent properties. 2—VULCA 100—an ether derivative of ungelatinized starch. Its granules are unaffected by heat or chemicals. Can be autoclaved without appreciably changing its properties. 3—CLEAR-FLO—the sodium salt of a low substituted starch acid ester derivative. Easy to prepare, free flowing, clear and smoothly textured. Won't 'skin over' on long exposure to the air. Unaffected by freezing.
Glue that plans our defense What helps to develop new ideas? Glue! Resin wood glue. Used everywhere from foundry patterns to pencils. Look at a pencil. It's made of two pieces of wood. A length of i6 lead." An eraser. All glued together. Next, walk through a pattern-making shop. Resin wood glue again! Moisture-resistant. Fast setting, in minutes, not hours. Non-abrasive so that knives and saws won't dull. Strength stronger than wood.
4—NU-FILM—a starch acid ester derivative containing sodium carboxyl a t e and s u l f o n a t e g r o u p s . H a s demonstrated unusual soil suspending ability and resistance to wet soil pick-up. 5—AMIOCA—a new type of starch consisting of pure amylopectin. Gelatinizes sharply after minimum cooking. Finished pastes resemble natural gums.
. . . where else is resin wood glue used? 3> "you name it... / helped make it!" What's a drawing b o a r d ? Wood glued edge-to-edge. And end-locked. With glue lines as soft as the wood. No hard ridges. Look at engineers' scales, slide rules, drafting tables, desks, office partitions and doors. The NATIONAL touch is everywhere. Glue applied through imaginative research and service. To every item of defense.
