In one process for waterproofing, a fabric is exposed to (CH3)₂SiCl₂ vapour. The vapour reacts with hydroxyl groups on the surface of the fabric or with traces of water to form the waterproofing film [(CH3)₂SiO], by the reaction n(CH3)₂SiCl₂ +2nOH →→→2nCl¯ + nH₂O + [(CH₂)₂SiO] where n stands for a large integer. The waterproofing film is deposited on the fabric layer upon layer. Each layer is 6.0 Å thick [ the thickness of the (CH3)₂SiO group]. How much (CH3)2 SiC1₂ is needed to waterproof one side of a piece of fabric, 1.00 m by 3.00 m, with a film 300 layers thick? The density of the film is 1.0 g/cm³.
