Developed by the Berlin company C.W.Zimmer AG, Zimmerit first appeared on German
tanks and SP guns in the summer of 1943. It's purpose was to combat the use of "sticky
bombs" and magnetic mines. The thickness of the of the zimmerit put distance between the
vehicle surface and warhead thus preventing magnetic contact with a shaped charged
mine whilst the irregular texture reduced surface adhesion for 'sticky bombs".
Zimmerit was a mixture of barium sulphate, polyvinyl acetate, zinc sulphide and saw dust.
Ochre pigment was added to mix giving it a dark yellow colour. Applied at the factory,
the mixture was smoothed over a vertical surfaces and a shaped tool used to rake in the
texture. Additionally, a knife was used cut grooves before the mix hardened.
By the middle 1944 the application of zimmerit was phased out. Reasons vary but it was
more than likely a combination of a number of factors. Time consuming to apply at a time
when AFV's were in desperate need at the front, the extra weight added to already
underpowered heavy tanks and the increased effectiveness of AT weapons. There is also
the belief that rounds hitting the vehicle caused the zimmerit itself to ignite.
