WARFARE ADHESIVE AGENTS (U).
M. A. Schmoke and R. J. Smith, May 1960.
CONFIDENTIAL
The objectives of this investigation were to conduct laboratory
and field studies on the effects of varying climatic conditions on the
adherence of certain candidate radiological warfare (RW) liquid adhesives
“4
to road surfaces under conditions of realistic military traffic on these
adhesives.
The adhesives tested were polymethyl methacrylate (Lucite)
in ethylene dichloride, polystyrene in ethylene dichloride, and yellow
traffic paint, Fed Spec TY-P-li5a.
Tracer quantities of zirconium-niobium
oxide were mixed with all the adhesives to simulate the RW contamination
and for radiological evaluation purposes.
Laboratory tests were made in the Atlas Weather-Ometer to
determine the effects of moderate and high temperatures and humidities on
the durability of the adhesives. Four field tests were conducted to
}
determine the adhesives' durability under various traffic and climatic
conditions:

winter, passenger vehicles; (2) summer and fall,
passenger vehicles; (3) winter, tanks and heavy trucks; (4) fall, military

The conclusions to be drawn from this report are: |
1.
Varying weather conditions have no appreciable effect on
the bonding properties of the polystyrene adhesive formulation.
2.
The polystyrene adhesive formulation demonstrates excellent
adhesive and wear resistance on asphaltic roadways under heavy and light
military traffic up to the test traffic density of 3,000 vehicles a month.
3.
The polymethyl methacrylate edhesive formulation shows very
