５：２５である。That is, when only γ-glycidoxypropyltrimethoxysilane is used, an aqueous inorganic composition having excellent adhesion to a substrate and excellent air-drying property (natural drying property) can be obtained, but the dry film is boiled. Not sufficiently resistant to water.
When dimethyldimethoxysilane is added to this, the water resistance is improved and it becomes sufficiently resistant to boiling water. However, if the ratio is too large, the stability of the obtained aqueous inorganic composition deteriorates and gelation occurs in a short time. Therefore, the weight ratio of γ-glycidoxypropyltrimethoxysilane to dimethyldimethoxysilane is 85:15 to 60:40, and more preferably 7:15.
It is 5:25.
