Have some of the zinc-silicate coatings such as Dimetcote (Amercote) or zincilate been tried?
No zinc silicate coatings were tried during the earlier period of this investigation. So far as the author knows, none were available for trial at that time. More recently, laboratory tests of one commercial coating of this type were started. These fests are not complete, but the coating is still in a satisfactory condition after 38 weeks in test.
Question 1 has been answered on page 197 of the published article.
Answer to question 2.—The polysulfide type coating (proprietary) was self-primed. The vinyl-type coating (proprietary) consisted of one gray primer coat, three gray body coats, and three black seal coats. The author has no information as to the composition of the primer coat. The Saran-type coating was self-primed.
You mentioned a cost of $300 for coating a tank car with Saran lining. How did you arrive...
