Pour water into your beaker of 0.1 percent to 2.0 percent concentration. These measurements are the same as 1 to 20 milligrams of water. The amount will depend on how much silane you are diluting. If you are using silanes that are not water soluble, mix your water with equal amounts of alcohol.
Add 1 to 20 milligrams of acetic acid to your water. Mix with a stirring rod to ensure acid is completely mixed with the water. Add solid silane cubes one at a time to the mixture.
Stir your solution for 30 to 60 minutes to full dissolve the solid silanes. Your solution becomes clear as the silane is dissolves into the water/acid mixture. Filter if silane is to be used more than once.
