Photopolymerizable coatings

Most commonly epoxy- or urethane acrylate resins are used as a basis with 

As an illustration a few parameters of typical commercial urethane acrylate coatings are listed in Table 1 together with those of recently developed materials. 

and also provide lists of optical, physical and mechanical properties. 

Characterization and evaluation of performance by means of the torsional pendulum technique has been discussed by Hussain Wierenga et al. have used ultramicro indentation measurements for the determination of the viscoelastic properties of coated optical fibers 

Recently, polyether urethane acrylates and poly(dimethyl-co-methylphenylsiloxane) acrylates have been reported as potential fast-curing, low-modulus coatings for high strength optical fibers
