Radiation curable optical fiber coating composition |
摘要 |
Provided is a radiation-curable, glass optical fiber coating composition which when suitably cured exhibits resistance to attack from hydrocarbon gel cable filing material. The composition contains about 10 to about 90% by weight of a first radiation-curable oligomer; from 0 to about 40% by weight of a reactive diluent; from 0 to about 40% by weight of a photoinitiator; from 0 to about 10% by weight of a pigment; and about 10 to about 90% by weight of a second radiation-curable oligomer according to the following formula:R1-L1-C1-L2-R2(1)where: R1 and R2, independently, each represent a radiation-curable functional group; L1 and L2, independently, each represent an alkyleneoxy chain having from about 2 to about 40 carbon atoms, wherein L1 and L2 are linked to C1 through an oxygen atom C1 comprises a hydrocarbon having from about 5 to about 40 carbon atoms and containing at least one cyclic group.
