Types of Adhesives: Sealants

D51531 Gasketing Flange SealantToday we will be starting a new series on types of adhesives! This series will run for three weeks, and will cover all of the adhesives that we carry at www.All-Spec.com. We will begin by looking at various types of sealants.

In general, sealants are used to close gaps in products. This allows the user to seal holes or gaps to not only keep foreign objects out, but to also protect the product itself. One of their main types is gasketing flange sealant.

To better understand what gasketing flange sealants do, it helps to take apart its name. A gasket is a seal that is used to fill space between two surfaces, helping to prevent air or liquid leaks. Flanges are flared ends, typically of pipes, which are used to provide larger surface area allowing them to be better connected to other pipes. A gasketing flange sealant is a liquid that you put between two flanges, and when it hardens it becomes the gasket that prevents leaks.

There are other types of gasketing sealants as well, which are made for other applications. Again, these are all used to help prevent leaks, the main difference lies in what they can be used for. Some are oil resistant, making them great for use in automobiles, while others are waterproof for use with plumbing. If you have any area with two hard metals, plastics, or resins that are touching, then gasketing sealants can help close the gap and ensure that no contaminates can get in and that no liquids or gasses can get out.

Gasketing sealants also help to create a buffer between hard materials, so they do not rub against each other. This can prevent some wear and tear on products, giving you a longer lifespan with less erosion in the machine itself.
