In this case, a glass wall remained dry. Bloomingdales does not necessarily agree. In 2 cup water was sprayed from the nozzle in one click of the lever, the torch nozzle was sent directly into a glass. As a result, at the bottom and walls of glass formed small droplets of water across the surface. Water temperature in the cups was about 15 C. Glass number 3 – dry. Tumblers set were placed in the freezer, where were kept about 2 – 3 minutes. After keeping the cup in the chamber which was released at polyurethane foam aid dispenser gun. Pre-cylinder was thoroughly shake and had a temperature of about 20 C.

Beakers filled with foam, one after another, without interruption. Total time filling three glasses was about 8 – 9 (Eight – nine) seconds, ie we can assume that they are filled almost simultaneously. Also been done for the second grade foam. Beakers were kept in the freezer – the chamber at a temperature of minus 10 – 12 C relative humidity of about 58 – 62 percent within 48 hours. Results of the experiment in a glass number 1 polyurethane foam greatly subsided. The lower area, located close to the water has a fairly homogeneous structure without any major far. By increasing the thickness of foam relative to the surface water quality of the material significantly and dramatically reduced.
