摘要： Optical fibers are coated with a radiation-curable liquid, polyethylenically unsaturated coating composition consisting essentially of an organic polysiloxane having from 2 to 6 reactive side chains each of which carry a functional group providing one reactive site which has been reached to provide a single radiation-curable monoethylenically unsaturated side chain. There are about one such side chain for every 500 to 5,000 units of molecular weight. This provides a prime coating which has a modulus of elasticity at room temperature and at -60.degree. C. below 3000.

摘要： Thermally curable wet-impregnated rovings are disclosed in which the fibers of the roving are impregnated with a liquid polyepoxide having dispersed therein a latent heat-activatable epoxy curing catalyst, such as dicyandiamide, the polyepoxide dispersion having a room temperature viscosity of from 2000 to 5000 centipoises and a tack of less than about 6 on a Thwing-Albert inkometer. The rovings are produced without organic solvent by passing a dry multifillament roving through an elevated temperature bath of the polyepoxide dispersion, this elevated temperature being insufficient to activate the curing catalyst and functioning to lower the viscosity to enable uniform impregnation. The wet rovings are stored in a supply package.
