Heat resistant glue is designed to withstand high temperatures without melting or degrading. It may have bonding issues with certain materials and color and bond strength should be considered. Different brands are suited for different purposes, so choose a glue that meets your needs without exceeding them.
Heat resistant glue is similar to any other type of glue, but is particularly resistant to higher temperatures due to its chemical composition. Heat resistance is a major concern with this type of glue, so you should make sure it can withstand the amount of heat generated or experienced by the substrate it will be used with. Depending on the brand of the heat resistant glue, there may be some materials that the glue cannot adhere to, and you should check this before choosing a brand. If the glue will be used in obvious places, the color of the glue may matter. Along with this, you need to check the bond strength especially if you are gluing heavy objects.
The main difference between heat resistant glue and any other glue is that it does not bubble, melt or otherwise degrade at high temperatures. This glue is specifically designed to be used at high temperatures, but it may still be a good idea to determine how much heat the glue can handle. Stronger glue usually costs more than less strong glues, so it may be best to get a glue that meets your needs but doesn’t vastly exceed them.
In addition to being good against heat, heat resistant glue is similar to regular glue. It may have bonding problems with certain materials, such as wood or plastic. No matter what type of material you’re gluing, it’s normally a good idea to know what materials a particular product can bond with, so you don’t accidentally get an ineffective adhesive that can’t glue your item together.
Glue is sometimes used in a conspicuous spot that is easily visible, although it can also be hidden from view. If heat resistant glue is used extensively, it may be a good idea to check the color of the glue and its ability to melt when dry. Clear, transparent glues may work well for this, but clear glue can still have a whitish color that is clearly visible against the surface of a darker substrate.
There are both general and industrial brands of heat resistant glue, and while some will be fine for household items, others will be best for heavy objects such as large pieces of metal or wood. Depending on what you want to adhere to, you should choose a glue that has enough strength to hold the item together. You can always go for a stronger glue bond strength but, like higher heat resistance, this drives up the price of the glue and may actually prove ineffective for lightweight items.
