摘要:
Provided is a ribbon assembly having the functional capability of providing mid-span access without the use of additives, monomers or oligomers containing fluorine or silicone. The ribbon assembly is formulated from an oligomer which reduces the surface energy of the ink coating and/or the matrix material.
摘要:
Provided is a ribbon assembly containing a plurality of coated optical glass fibers and a matrix material which binds the plurality of coated optical glass fibers together. At least one of the coated optical glass fibers contains an ink coating or colored outer primary coating. At least one of the ink coating, the colored outer primary coating, or the matrix material contains a phospholipid.

Provided is a ribbon assembly having the functional capability of providing break-out of ink coated or colored outer primary coated optical glass fibers from the ribbon assembly. The ink coating or colored outer primary coating is formulated from a benzophenone compound and at least about 1 wt. % of a homolytic photoinitiator to provide a level of adhesion between the ink coating or colored outer primary coating and matrix material which is less than the level of adhesion between the ink coating or colored outer primary coating and an adjacent underlying coating. Also provided are ink coating and colored outer primary coating compositions adapted to form ink coatings and colored outer primary coatings suitable for use on optical glass fibers contained in a ribbon assembly.
摘要:
The invention relates to a radiation curable composition including a polyester urethane (meth)acrylate oligomer prepared from ortho-carboxylic polyester polyols, where the composition, after cure, has a secant modulus greater than about 600 MPa and an elongation at break of at least about 10%. The invention also relates to coated optical fibers and optical fiber ribbon including at least one coating derived from this composition, and to a process of making these coated optical fibers.
摘要:
Provided is a ribbon assembly having the functional capability of providing break-out of ink coated optical glass fibers from said ribbon assembly. The monomers, oligomers and photoinitiator for forming an ink coating on the optical glass fibers contained in the ribbon assembly have been selected to provide an average percentage of reacted acrylate unsaturation which provides a level of adhesion between a matrix material and an ink coating that is less than a level of adhesion between the ink coating and the coated optical glass fiber to provide break-out of the ink coated optical glass fiber from said ribbon assembly. Also provided are ink coating compositions adapted to form ink coatings suitable for use on optical glass fibers contained in the ribbon assembly.
摘要:
A composition which is cured upon exposure to ultraviolet light in the absence of solvent is disclosed. The liquid composition is prepared by combining a liquid maleate polyester and at least one of a vinyl compound and an allyl functional compound. A photoinitiator is then added to the polymerizable liquid composition. A substrate is impregnated with the polymerizable liquid composition and exposed to actinic energy of a sufficient dosage for a sufficient amount of time to polymerize the composition to a sufficient degree to impart useful properties to the substrate. The composition can be used as a binder for fiberglass insulation, in the manufacture of transparent or semi-transparent paper and to manufacture paper for use in photocopy machines.

摘要:
Provided is radiation-curable ink composition containing a radiation-curable carrier system containing at least one radiation-curable monomer or oligomer and at least one pigment dispersed in the radiation-curable carrier system in an amount sufficient to provide a color which is visible without magnification. The pigment is substantially insoluble in the radiation-curable carrier system whereby the particulate shape of the pigment is substantially retained in the radiation-curable carrier system. The pigment having a particle size that substantially avoids pigment induced microbending of an optical glass fiber coated with the ink coating.
