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.

Radiation-curable optical glass fiber coating compositions, coated optical glass fibers, and optical glass fiber assemblies

Optical fiber primary coating systems are disclosed having excellent ribbon stripping and adhesion behavior. The coatings are radiation-curable. The excellent stripping and adhesion behavior can be inner piramry coating composition having a slip enhancing component and a high modulus outer primary coating composition. Combination of means can be employed. Stripping behavior can be measured by crack propagation and fiber friction measurements.

Radiation-curable optical fiber primary coating system

A method of cleaning a substrate by covering the substrate with a composition in a sufficient amount to clean the substrate. The composition includes a substantial amount of at least one low viscosity organic compound which includes a radiation curable group. The compound is reclaimed for further use. The reclaimed compound may be used as a reactive diluent in a radiation curable coating composition.
