Paint coatings continued causes

To rinse, wash the surface in clear, continuous running water to remove all traces of soluble salts which may cause blistering on the surface. The tank can be similar to the phosphating lank. It may, however, be coated with an anti-corrosive paint to extend its life. 

In all the paint systems tested in the atmosphere, the presence of the chloride contaminant at its highest concentration, causes the appearance of small blisters. Such blisters may in time burst due to the oxide built-up inside them, as was seen in the case in the CR system ("Table III.") In the P system ("Table III."), the blistering seen with the third level of chlorides continues after two years outdoor exposure, without rust coming through the coating. This same effect is also seen in salt fog test panels, but it does not appear in those test specimens subjected to accelerated weathering tests. 

Continuous efforts have therefore been made to develop binders for one-pack paints which must be completely compatible with active pigments such as zinc dust. Mixtures of ethyl silicate and zinc can be stored for unlimited periods in the absence of water. If the hydrolysis and condensation reactions caused by atmospheric moisture can be sufficiently accelerated during application of the coating, a one-pack system can be produced. 

Ozone can lead to the development of cracks in products made of rubber or sjmthetic rubber, such as tires, boots, gloves, and hoses. Continued expostire to high levels of ozone can cause these products to disintegrate completely. Ozone accelerates the fading of dyes damages cotton, acetate, nylon, polyester, and other textiles and accelerates the deterioration of some paints and coatings.
