...used to put a lusterless coating (which must be renewed from time to time) on blue serge and to impregnate wool so that it achieves a durable crease when pressed under heat. To make wool shrink-proof, Powers first wets it to open the fibers, then injects a resin inside the hollowed fibers. This stiffens the tiny, fuzzy barbs that stick out of the side of a woolen fiber and prevents the barbs from interlocking - the cause of shrinkage...
Developed by the Hercules Powder Co., which worked on the problem for many years, the new method involves a powdered resin called Stabinol. The powder is spread on the soil, a few pounds per square yard; then it is harrowed in six inches deep and the soil is packed hard with a steam roller. The result is a smooth, dry surface that sheds water like a duck's back. It is good for tennis courts, athletic fields, earth dams-and especially for roads. The Army has already begun to use it for roads and airfields...
...tree sap, the powder is a cheap (less than $5,000 per mile of 40-ft. road), quick road-builder. It works something like sizing in coated paper; a mixture of about 1% of Stabinol in ordinary soil prevents water from penetrating in sufficient quantity to soften it. A resin-stabilized road stays so dry that even when it is covered with a layer of water a truck driven over it throws up a trail of dust. Stabinol does not waterproof sand (because sand lacks a binder to make it solid) and it does not work on ground that...
...start in 1880 when, as the youngest student at the University of Ghent, he developed Velox paper, a photographic milestone which killed tintypes and netted him a reputed $1,000,000 from Eastman Kodak. Baekeland made possible the "improbable sandwich" (plywood) by his work in 1912 on a synthetic resin filler. He was also honored for : separation of cadmium and copper, oxidation of hydrochloric acid under light, dissociation of nitrate of lead, industrial electrolysis of alkali chlorids...
...ever duplicated shellac's complicated chemical structure. But Chem ist C. G. Harford, of the Arthur D. Little laboratory in Cambridge, Mass., found that a resin named zein, derived from corn, behaved very much like shellac. A drawback, however, was that in solution zein had a tendency to jell. By an un disclosed chemical process, Harford finally succeeded in converting zein into a non-jelling resin. The result, Zinlac, not only has the quick-drying, elastic qualities of shellac, but is also more resistant to water and makes a better coat for metal...
