A sealant is a material used to fill the gap between mating surfaces to create an airtight, watertight or weathertight joint. It can be applied to the surface before joining parts or sprayed into the joint, depending on the type of sealant. Unlike adhesives, sealants do not permanently lock the two surfaces together and may require mechanical fasteners to maintain contact. Sealants are available in a variety of forms, including pastes and liquids. The choice of a sealant depends on a number of factors, including the surface to be sealed, the load to be imposed and the environmental conditions.
Some important specifications to consider when choosing a sealant are its adhesion, tensile strength, compression set and flexibility. Adhesive and sealant manufacturers often provide accelerated weathering testing results for their products, which can help users determine whether a product will remain durable and withstand environmental conditions.
A good sealant should be flexible to allow the component to expand and contract with changes in temperature. It should also be capable of resisting vibration, impact, moisture and harsh environments. It is best if the sealant does not contain toxic or harmful chemicals and is easy to clean up.
Many sealants are designed to be used in particular applications and environments. For example, some are formulated to resist the presence of water, dirt and other contaminants, while others are formulated to withstand high temperatures or low humidity. The characteristics of a sealant are determined by its base polymer, which may be acrylate, silicone, epoxy or some other material.
Some sealants are designed to be used in conjunction with specific materials, such as rubber, metals or glass. They are formulated to adhere well to these materials and also to bond with other substances, such as concrete or masonry. The properties of a sealant may be further defined by its viscosity, flowability and other physical and chemical characteristics.
When choosing a sealant, it is also important to consider the cost of the product and the speed at which it will cure. The price of a sealant is determined by its formulation, performance and market demand. It is advisable to consult with several Sealant Manufacturers and obtain pricing information for the type of sealant that is most appropriate for a project.
