摘要:
An anti-fog coating composition is described comprising an aqueous polymeric dispersion; a crosslinker, and a surfactant. The dried and cured coating composition does not exhibit fogging within 8 seconds after being soaked in 25° C. water for 1 hour. In favored embodiments, the dried and cured coating composition does not exhibit fogging within 60 seconds after being soaked in 50° C. water for 24 hours. Also described are articles comprising the dried and cured coating composition disposed on a substrate as well as a method a providing an anti-fog coating on a substrate.

摘要:
The present invention is a method of coating an adhesive layer. The method includes non-contact depositing a fluid solution onto the adhesive layer and allowing the fluid solution to substantially dry, where the fluid solution comprising a biological active. The fluid solution exhibits a Hildebrand solubility parameter of at least about 3.7 MegaPascals1/2 greater than a Hildebrand solubility parameter of the adhesive layer.
