Use silicone as an adhesive and what to watch out for

Gluing with silicone and what to look for

The silicone sealant is also suitable for use as an adhesive in many cases. Not every user knows that. However, there are a few things to consider and some sealant limitations. In fact, silicone has some advantages that make it seem well-suited as an adhesive, such as the following:

  • can be used in a wide temperature range (depending on the type)
  • is resistant to UV radiation
  • permanently elastic and electrically insulating
  • Silicone glue has good adhesive properties

Use sealant or silicone glue for gluing

Because of its soft consistency, silicone is very well suited to be used as an adhesive. However, you can achieve better results than with conventional sealing silicone with a special silicone adhesive. This is offered in cartridges like conventional sealant (€ 17.59 on Amazon *). You will also receive a two-component adhesive, which usually has even better adhesive properties than an adhesive with one component. The two-component adhesives are very popular for heavily used surfaces. It is precisely here that you should not use conventional silicone sealant as an adhesive, especially not when it comes to surfaces that are subject to constant movement, whereby the adhesive surfaces can tear if unsuitable adhesives are used.

Important information on gluing with silicone

It is important during processing to distribute the adhesive or silicone evenly on the adhesive surfaces. You can either work across the board or distribute several equal amounts of glue in points on the respective surface. However, do not apply the adhesive too thickly. A few millimeters are enough. The sealing surfaces must then be pressed together firmly until the adhesive has completely dried out. Corrections can still be made for a short time as long as the mass has not yet dried out. After that, the surfaces should rest. If you use special silicone adhesive, be sure to pay attention to the processing instructions on the cartridge for the adhesive. As a rule, the adhesive surfaces are dried out after 24 hours and can be stressed or stressed.
