Types of Glue for Glass
Glass is a rather unique material that can prove rather difficult to bond. It is paramount you use the correct type of glue to have the sort of successful results you would expect.
Your decision ultimately comes down to three types, epoxy, super glue or silicone sealant, each of which are represented by one or two products on this list.
Epoxy is a liquid adhesive that typically comes in two parts, a resin and hardener, that need to be mixed in a 1:1 ratio to create an epoxy glue. The bond they form is much stronger than those formed by super glue. Set times compared to super glue are longer, giving you more time to apply the epoxy and position your materials.
Along with great tensile strength, epoxy’s feature excellent temperate and chemical resistance which make them a great choice for industrial applications, for example, medical equipment. You certainly won’t have to worry where you use your epoxy, indoors or out
When handling an epoxy glue extra care should be taken to avoid it coming into contact with the skin. Fortunately, most come with a small mixing tray and stir stick to make the process as safe as possible while ensuring an even spread for maximum hold.
Epoxy glue is the appropriate choice for those looking for a maximum strength glue that will stand up to extreme conditions and shear force.
Perhaps the most commonly used adhesive around the world and certainly the most well-known, super glue offers a strong bond and is super-fast setting. They are available in a few different variety’s each designed for a different surface such as glass, plastic, wood, metal and more.
The quick setting properties of super glue make it a good choice for quick, on the fly repairs as no clamping is required. Unlike epoxy’s which must be mixed before use, super glue is ready to be applied straight from the bottle.
Although the quick setting properties of super glue can be incredibly helpful in many circumstances, there are some in which it is not. For example; it may not give some users sufficient time to position the materials being glued. To avoid mistakes try aligning your materials before applying the glue. You should avoid using super glue when making repairs in extreme weather conditions and on areas that experience shear forces.
Go for super glue if you require an adhesive for delicate applications and smaller-scale jobs that are non-weight barring.
Silicone sealant is a powerful and flexible liquid adhesive that acts like a gel and forms a tough, waterproof, mold and mildew resistant bond that will not crack or shrink once cured. The gel-like consistency of the silicone allows it to reach places that may otherwise be missed to ensure the entire area is sealed.
Due to its highly resistant nature, it is commonly used by households for both indoor and outdoor use and in the automotive industry. Some applications include windshields, lens housings, windows, door frames and glass.
The ability to flex make silicone sealant a great choice for high-stress bonds such as those involved in glass applications but not a good idea for weight-bearing bonds. Go with silicone sealant if you need a resistant adhesive that will stand up to the test, no matter the conditions.
