Silicone Glass Glues Restrictions
Various silicone glass glues are subject to the following restrictions when used:
1. It is not suitable for construction in a place with long-term flooding;
2. It is not compatible with materials that can ooze grease, plasticizer or solvent;
3. No adhesion on frosted or wet surfaces;
4. It cannot be cured in a completely sealed place (silica gel needs to be cured by moisture in the air);
5. When the surface of the substrate is not clean or firm, it cannot be bonded.
Acid silicone glass glue will corrode or cannot bond copper, brass (and other copper-containing alloys), magnesium, zinc, electroplated metals (and other zinc-containing alloys), and it is recommended to make masonry materials and ferrous carbide substrates Do not use Acid glass glue. It will not be good if used on materials made of methyl methacrylate (PLEXIGLAS), polycarbonate, polypropylene, polyethylene and TEFLON (Teflon, polytetrafluoroethylene) Bonding effect and good compatibility.
Acid glass glue is not suitable for connections that move more than 25% of the joint width. Ordinary acid glass glue should not be used on structural glass (except for acid structural glue). In addition, it should not be used in places where there is abrasion and substantial disadvantages. Use acid glass glue. The surface temperature of the base material of the silicone acid glue exceeds 40℃ and it is not suitable for construction.
