All kinds of silicone rubber will be subject to the following restrictions when used: 1, long-term immersion place is not suitable for construction; 2, do not dissolve with the exudate oil, plasticizer or solvent material; 3, frost or wet surface can not be bonded; 4. The completely closed place cannot be cured (the silica gel needs to be cured by the moisture in the air); 5, the substrate surface is not clean or firm.
Acid glass glue has the following restrictions:
Acid silicone adhesive corrodes or fails to bond copper, brass (and other copper alloys), magnesium, zinc, electroplated metals (and other zinc alloys), At the same time, it is recommended not to use acid glass glue on the materials made of brick and stone materials and iron carbide matrix, because it will not be able to get good bonding effect and good compatibility if used on the materials made of methyl isobutenate (PLEXIGLAS), polycarbonate, polypropylene, polyethylene and TEFLON (TEFLON). Move more than 25% of the joint width of the connection is not suitable for the use of acid glass glue, in the structure of the glass is best not to use ordinary acid glass glue (except acid structural glue), in addition to erosion and will produce substantial disadvantages should not use acid glass glue. The surface temperature of the base material of acid silicone rubber is more than 40℃.
