Why Use Silicone Paste?

Silicone pastes are a multi-purpose compound that can be used as a sealant, grease, lubricant, or adhesive depending on the situation. It is an excellent heat sink and insulator that also offers moisture, dirt, and chemical resistance. A silicone-based paste allows parts to move freely while protecting them in tough environments.

Common applications for silicone paste include waterproofing surfaces, sealing pipe connections, bonding sensors, lubricating plastics, and preventing electrical arcing. Many pastes have a consistency of petroleum jelly, helping it stay in place when subject to gravity or mechanical stress. Other silicone pastes are two-component formulas that form a solid layer, which is excellent for making gaskets or sealing materials.
