Methoxy butanol, also known as methyl ethyl ketone, is a clear liquid with a mild, sweet smell. It is used as a solvent in the production of paints, lacquers, and adhesives, and as a fuel additive.
When rubber is exposed to methoxy butanol, it can cause swelling, softening, and discoloration. Additionally, prolonged exposure to methoxy butanol can cause rubber to become brittle and to lose its strength and elasticity. The presence of air or water vapor can also accelerate the degradation of rubber when exposed to this chemical. In some cases, the rubber can become so brittle that it is no longer usable.
