Aqueous akaline developable, UV curable urethane acrylate compounds and compositions useful for forming liquid 100 percent solids, solvent-free solder mask coatings

摘要

Aqueous alkaline developable, UV curable urethane acrylate compounds and compositions are particularly useful for making flexible, 100% solids, solvent-free solder mask coatings which are characterized by having screen-printable viscosities, rapid developability and advantageous performance characteristics.
