Chapter 8 – Formulas and Specifications



Section 8-A.



Previous editions of this publication have shown in detail the manufacturing  formulas of all paints and varnishes, as a basis for the control of quality.  Specifications are now in preparation for all of the paints and varnishes specified herein by formula designation.  Pending issue of specifications printed sheets for each formula are available in most instances for distribution, giving manufacturing details.  However, specifications and formulas for anticorrosive, antifouling, boot-topping, submarine ballast and submarine superstructure coatings are not furnished to contractors because the necessary close control of quality of products is impracticable.  These products will be supplied as government furnished items.  Specifications where applicable or in lieu thereof standard manufacturing formulas which have been approved by the Bureau shall govern the procurement of materials from commercial sources and the manufacture of products by the navy yards.


Containers shall be labeled with the name of the paint and the formula designation.


The following are the formula designations and specification symbols where applicable to date, with a brief statement of the purpose for which the product is used primarily and also including its indicated suitability for other purposes.

Film thickness – spreading rate.- Emphasis has been placed in chapter 1 upon a maximum film thickness of paint on interior surfaces to minimize the fire hazard and to save weight.  Film thickness involves spreading rate and volume of nonvolatile components of a paint.  Also, it is often desirable to know the spreading rate of a paint in estimating costs.  For ready reference a graph is shown indicating the relationship between spreading rate, film thickness, and volume of nonvolatile components.  If the value of any two of these properties is known the third can be determined from the chart.  For example, if the spreading rate is known to be about 400 square feet per gallon and the nonvolatile component volume is 40 percent, the average thickness of the dry film should be .0016 inch.  If the inspector measures the film thickness and finds it averages about .0024 inch he will know that the spreading rate was about 275 square feet per gallon or that  more than one coat was applied.


The volume of the nonvolatile components of a paint can be computed from the manufacturing formula.  As an example, the steps in determining the value for the nonvolatile components in the zinc-chromate primer, formula 84, are given:
