Optical fiber coatings are disclosed having excellent ribbon stripping and adhesion behavior. The coatings are radiation-curable. The excellent stripping and adhesion behavior can be achieved by several means which include by use of additives, by use of radiation-curable oligomers having higher molecular weight, or by use of coatings having certain thermal properties. Combination of means can be employed. Stripping behavior can be measured by crack propagation and fiber friction measurements.

The present invention relates to optical fiber coatings, inks and matrix material structures such as bundles or ribbons, and methods of curing the same, using low power electron beam radiation. The optical fiber substrate is not substantially degraded following exposure to the low power electron beam radiation during the curing process.

Method for curing optical glass fiber coatings and inks by low power electron beam radiation

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.

A method is disclosed for increasing the adhesion of a radiation-curable coating composition to a surface which comprises treating the surface with a fluorine-containing gas before application of the coating and curing the coating composition by exposure to radiation. The increased adhesion of radiation-curable pigmented coating compositions to treated magnetic recording structures, such as tapes and disks, is particularly contemplated.

Radiation-curable coating compositions applied to fluorine-treated

A concrete mix comprises a cementing agent and aggregate, the aggregate comprising vesiculated beads of cross-linked resin which beads contain an average of at least 2 thin-walled foraminous cells to provide communication between the vesicles within said bead and the exterior of said beads to allow water to move into and out of said beads. This reduces the density of the concrete and the beads hold water to help control the cure.
