MIL-0E-09500, also known as Methyl Ethyl Ketone (MEK), is a highly flammable and volatile organic compound commonly used as a solvent in the paint, coating and adhesive industries.
When rubber is exposed to MEK, it can cause the material to swell, leading to a loss of strength and elasticity. The solvent can also corrode the rubber, leading to cracks and holes in the material. It can also cause the rubber to degrade, leading to discoloration, brittleness, and ultimately loss of physical properties. In addition, the solvent can dissolve certain types of rubber, causing it to lose its shape and become brittle.
