RADIATION-CURABLE OPTICAL FIBER COATINGS HAVING REDUCED YELLOWING AND FAST CURE SPEED |
摘要 |
<p>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.</p> |
