The use of all kinds of silicone glue will be subject to the following restrictions: 1, long-term immersion of the place is not suitable for construction; 2, do not meet the seeping oil, plasticizer or solvent of the material dissolved; 3, frosted or wet surface can not bond; 4, completely closed place can not be cured (silica gel needs to be cured by moisture in the air); 5. The surface of the substrate is not clean or firm.
Acid glass glue has the following restrictions:
Acidic silicone adhesives will corrode or fail to bond copper, brass (and other copper alloys), magnesium, zinc, electroplated metals (and other zinc alloys), At the same time, it is suggested that acidic glass glue should not be used on materials made of brick and stone and iron carbide matrix. It is not possible to obtain good bonding effect and miscibility when using this product on materials made of methyl isobutylene (Plexiglas), polycarbonate, polypropylene, polyethylene and Teflon (Teflon, PTFE). Moving 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 also best not to use ordinary acid glass glue (except acid structural glue), in addition to wear and will produce substantial drawbacks should not be used in the place of acid glass glue. Acidic silicone rubber substrate surface temperature over 40℃ is not suitable for construction.
