    Reactive silanes are more typically used as adhesion promoters or couplers. The silane reacts with metals and especially water in metal oxide coatings and pins itself to the substrate. Some silanes combust spontaneously when dumped in a lab sink. The methoxyls or other organic groups are compatible with the adhesives system used.

    Methanol is often used as a carrier solvent in silicone systems. Anyone who has used a platinum catalyzed silicone rubber has smelled it when adding the catalyst. The methanol warning is needed because drunks used to destroy their optic nerves, or died, when trying to drink it, but in trivial sub-gram quantities the MSDS is scarier than it needs to be. Lawyers, you know.
