Bordeaux mixture is a combination of copper sulfate and calcium hydroxide, also known as slaked lime. It is commonly used in gardening and agriculture as a fungicide and insecticide.
When exposed to Bordeaux mixture, rubber materials may become brittle, leading to cracking and splitting. The copper sulfate in the mixture can cause corrosion of the rubber material, leading to further weakening and degradation. Additionally, calcium hydroxide can cause the rubber to become more porous, leading to increased absorption of liquids, which can lead to further degradation of the rubber.
