Humidity during storage

The reactions of amines and isocyanates are important in adhesives because of the possible reaction of isocyanates with water. Because isocyanates react readily with water, raw materials used in formulating adhesives must be dry, and the compositions must be protected from moisture, including atmospheric humidity, during storage. The first reaction...

Polyurethane liner pads employed in naval missile launch systems are exposed to high humidities during storage and occasionally to sea water after their installation. In order to determine their durability towards water, a detailed study was made of their hydrolytic stability. Even though both polyether and polyester based urethanes can give the physical properties required for this application, only the polyether urethanes were studied since they display much superior resistance to hydrolysis (1, 2, 3, ). 

Water is the most influential parameter directing the environmental attack on glass. Therefore, the optimisation of relative humidity during storage and display...
