What is a Seam Sealer?

A seam sealer is a material used to seal gaps or joints between two surfaces to prevent water, air, or other substances from penetrating through. It is commonly used in automotive, marine, and construction industries to seal seams in vehicle bodies, boats, or buildings.

There are different types of seam sealers available, but most of them are made of a combination of polymers and resins. The most common polymers used in seam sealers are polyurethane, silicone, and acrylic, while the resins used are usually epoxy or polyester. Each type of sealer has different properties and is suitable for different types of applications.

Seam sealers come in different forms, including tapes, liquids, and pastes. Tapes are usually used for temporary seals, while liquids and pastes are more permanent

Polyurethane glue otherwise referred to as PU adhesive, is used in situations that demand extremely high durability. The degree of elasticity offered allows for use for static as well as for more tactile bonding purposes. These adhesive types are formulated from polymers and commonly have a variety of other types of additives in them too.

The Science

In the case of polyurethane adhesive – also known as PU adhesive – this means that the liquid glue will become rigid when exposed to air at room temperature. When polyurethane adhesive sets, it absorbs the energy in heat to power a chemical reaction and create a very high strength bond.

Polyurethane adhesive commonly finds usage as a dual-component adhesive, but it can be found in single-component varieties as well. Either relies on the reactivity of several chemical agents for the adhesive properties, which can often make use of a catalyst like moisture, light, or heat in the process. The adhesive oft
