摘要:
The present invention provides radiation-curable compositions for coating plastic substrates, wherein the compositions, after cure, have a combination of sufficient adhesion, flexibility, and hardness. The compositions include: (a) at least one component comprised of a metal oxide bonded to an organic compound, said organic compound having (i) a radiation curable group; and (ii) a group represented by the following formula (1): wherein X represents an amine (NH), oxygen (O), or sulfur (S) radical; and Y represents an oxygen (O), or sulfur (S) radical; (b) a poly(meth)acrylate compound; and (c) an adhesion promoter.
摘要:
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.
摘要:
Radiation-curable inner and outer primary optical fiber coatings are disclosed having both fast cure speed and reduced rates of yellowing. The compositions comprise particular photoinitiators and UV absorbers which are used in amounts to provide the combination of properties. The UV absorber can have ethylenic unsaturation. Outer primary coatings can be formulated to screen inner primary coatings and have fast cure speed.

摘要:
A fast curing radiation-curable composition useful as coating compositions for inner and outer primary coatings, inks, ribbons other matrix material coating layers for coating and surrounding optical fibers. The improved radiation-curable compositions, having a propoxylated monomer or oligomer component, demonstrate unexpectedly fast cure speeds while providing strong adhesion characteristics to a variety of substrates and can also be used as a general radiation-curable adhesive or can be adapted for use in the specialized process of digital versatile disk (DVD) production.
