Projectile Interior Coating for Composition B Improvement
Abstract
A system for coating a projectile interior to provide corrosion protection for the steel and to bond the TNT-based explosive casting to the projectile has been developed. The coating material, which consists of an adhesion promoter combined with a polyurethane, has shown excellent properties in laboratory tests at low, ambient, and high temperatures. The coating is a 50/ 50 mixture of Estane 5715/VMCH with 1% Epon 828 dissolved in a 50/50 methyl ethyl ketone/methyl isobutyl ketone solution to give a 20% concentration. The coating material is being tested on a pilot plant scale and has been effective in several loading tests performed to date. This coating appears to be sprayable with standard commercial spraying equipment.
