Silicone gum is a kind of ointment that solidifies into a tough rubberlike solid material when it comes into contact with moisture in the air. Because it does not flow due to its own weight, it can be used over the top or side wall joints without sag, collapse or flow away. It is mainly used for the adhesion of dry and clean metal, glass, most non-greasy wood, silicone resin, sulfur-added silicone rubber, ceramics, natural and synthetic fibers, and many paint plastic surfaces. Good quality silicone glue in the zero degree Celsius below the use of extrusion will not occur, physical properties change and other phenomena. The fully cured silicone glue can maintain continuous effectiveness at temperatures up to 204 ° C (400oF), but the effective time will be shortened at temperatures up to 218 ° C (428oF). Silicone glue has a variety of colors, commonly used colors are black, porcelain white, transparent, silver gray, gray, bronze six. Other colors can be customized according to customer requirements.
Silicone gum can be divided into two categories from the product packaging: one component and two component. One component silicone glue, its curing is by contact with water in the air and physical properties of the change; Two-component refers to the silicone glue is divided into A and B two groups, any group alone can not form curing, but the two groups of glue once mixed will produce curing. Common on the market is one component silicone glue, this book to introduce this kind of glass glue.
One component silicone glue according to the nature and divided into two kinds of acid glue and neutral glue.
Acid glass adhesive is mainly used for general bonding between glass and other building materials. The neutral adhesive overcomes the characteristics of acid adhesive corrosion of metal materials and reaction with alkaline materials, so it is applicable to a wider range, and its market price is slightly higher than acid adhesive.
A special kind of glass glue on the market is silicone structural sealant, because it is directly used for glass curtain wall metal and glass structure or non-structural adhesive assembly, so the quality requirements and product grade is the highest in the glass glue, the market price is the highest.
