Publication number: 20150175865Abstract: A dehazing agent includes a polyethylene glycol compound of 6˜27 wt %, a modified organic polysiloxane mixture of 45˜60 wt % and alcohol. The surface of the article being sprayed or coated with the dehazing agent becomes hydrophilic such that the contact angle of a drop of water on the article is less than 10 degrees. As a result, it lasts for 30 minutes more without forming haze on the surface of the article. The article is thus applicable to humid and warm environments so as to assist the use to work for a long time in such a circumstance.Type: ApplicationFiled: March 20, 2014Publication date: June 25, 2015Applicant: National Taiwan UniversityInventors: Bor-Shiunn Lee, Chia-Wen Wu
