Antidepressant.: Doxepin HCL belong to a class of antidepressants called Tricyclics. Some of the side-effects include dry mouth, constipation, drowsiness or sedation, hypotension, dizziness, difficulty initiating the urinary stream, depression, suicidal thoughts and weight gain.
The life expectancy of paint coatings on new weathering steel is at least equivalent to the life of the same coatings on ordinary structural steel. It could even be argued that the life will be longer, as the weathering steel will resist any creep of corrosion under the paint from a damaged area.
Steel can suffer oxidation at temperatures above 400Â°C. This can be decreased by using weathering steels. At temps above 400Â°C weathering steels form a protective patina. A typical improvement would be an increase of 50Â°C over equivalent loss in carbon manganese steels.
