For Direct Application to Glass

Aerosol OT Surfactant is used in special formulations that are applied directly to glass surfaces to prevent fogging under adverse weather conditions. Some of these formulations give durable films that stand up under severe tests. An example of an excellent Antifog paste is as follows  

Heat the water to 1B0F and add the Aerosol OT-75% slowly with mixing. Sift in powdered gum tragacanth. Continue mixing until all gum is dispersed, cool to 105F, and add petrolatum. 

Dampen the corner of a piece of cloth with paste and rub over entire glass surface. Before film becomes dry, polish well with clean portion of the cloth. 

Aerosol DT Surfactant may also be cast into stick form. Softening agents such as glycerine or ethylene glycol are incorporated to simplify application to the glass surface. 

Such sticks, usually two to four inches long and one-half inch in diameter, are sold in kits for application to goggles, windshield wipes and bthroom mirrors.
