Hot Melt Sealants

The terms Hot Melt Sealants and adhesives are often used interchangeably since some formulations actually provide both functions. Sealants are generally chosen for their ability to fill gaps and resist relative movement of the substrates. Sealants are generally used as a barrier or a means of protection. In this way, sealants are used to exclude dust, dirt, moisture, and chemicals or to contain a liquid or gas. They are also often used as a coating to protect a surface or an article. They can exclude noise and vibration, improve appearance, and perform a joining function. Sealants can also be used as electrical or thermal insulators, fire barriers, and as products for smoothing or filleting. Most importantly, sealants are often used to serve multiple roles as they may be called upon to perform one or several of these functions
