1379279 Casts MERCK & CO Inc 13 Dec 1972 [20 Dec 1971] 57483/72 Heading A5R [Also in Division D1] A body cast material comprises a knitted or woven textile impregnated with an ultraviolet light-curable resin, textile being of a mesh of generally rectilinear openings with side dimensions of 0.045-0.150 inch and wale or warp yarns separating adjacent openings to provide a fabric thickness of 0.035-0.060 inch. When cured by the ultraviolet light, e.g. 3650-3720Š in less than six minutes. The textile forms a light, rigid, air-permeable, non-irritating cast the fabric may have lateral stretchability and resistance to lengthwise stretchability, e.g. Raschel knit, prior to curing of the resin. There may be up to 8 layers of fabric in the cast. There may be a knitted polypropylene stockinet within the cast. The yarns in the fabric may be glass of diameter 0.00015- 0.00021 inch, nylon or natural fibres. The curable resin may comprise a benzoin ether or ester of formula C 6 H 5 . CO . CHOR . C 6 H 5 (where. R is hydrocarbyl or -COR', R is hydrocarbyl and. preferably R and R' are methyl, ethyl, propyl, decyl or phenyl), a polyester formed from maleic anhydride, isophthalic acid and ethylene glycol, propylene glycol or butylene glycol, an unsaturated monomer such as. vinyl toluene, an aromatic phenolic type inhibitor, and tertiary-butyl catechol.
