Abstract: An optical fiber comprising a flame retardant UV light-curable tight-buffer coating coated onto the fiber, wherein said tight-buffer coating is substantially halogen-free, and has a limiting oxygen index of at least about 22%, and wherein said tight-buffer coating is removable from said fiber with a strip-force of less than about 1800 grams when the fiber is upjacketed with said coating at a line speed of at least 300 m/min.

Abstract: The present invention provides a curable liquid resin composition which, when cured, exhibits excellent removability from an adjacent coating layer and is suitable for an optical fiber upjacket material. The curable liquid resin optical fiber upjacket composition comprising a urethane (meth)acrylate or a (meth)acrylate oligomer, a reactive diluent, a polymerization initiator, and a polyol compound having a molecular weight of 1500 or more.

Abstract: Improved radiation-curable compositions and related methods useful in the assembly of optical components. These compositions cure via free-radical polymerization and comprise: about 30 to about 70 wt. % oligomer; about 10 to about 50 wt. % reactive diluent; and about 0.1 to about 40 wt. % adhesion promoter, wherein the cured composition exhibits a modulus of less than about 50 MPa, and a dry adhesion in excess of about 50 g force. A related aspect of the present invention is a higher modulus composition that cures via free-radical polymerization and comprises: about 30 to about 70 wt. % oligomer; about 10 to about 50 wt. % reactive diluent; and about 0.1 to about 40 wt. % polymerizable adhesion promoter, wherein the cured composition exhibits a modulus of greater than about 600 MPa.
