Body Panel Adhesive

Hot melt body panel adhesive for automotive assembly

Continuous development in close cooperation with our customers has led to a comprehensive range of products that bring our smart adhesive technology to the world of body panel adhesives. 

Our automotive weatherstrip adhesive and watershield bonding solutions are designed to exceed the toughest industry specifications, while saving you time in assembly and reducing your waste and adhesive consumption. 

We relish opportunities to work with our customers in order to provide the perfect adhesive for the perfect panel bond. If you’re interested in using our body panel glue on your assembly line and want personalized guidance on its usage, contact our account team directly. 

Composite bonding benefits

Our watershield adhesives require smaller beads, reducing consumption over standard hot melt pressure sensitive adhesives (HMPSA) by over 20%. They come ready for installation upon dispensing and due to their easy release from liners, are perfect for clean installations. Bostik watershield adhesives are also nonreactive and require no mixing, making them much safer to handle for line workers.

Our HMPSA and butyl automotive weatherstrip adhesives are foamable up to 50%, reducing the amount and weight of adhesive consumption while improving consistency. These smart adhesives also have the additional benefits of reducing interior noise and corrosion from standing moisture, while their repositionability characteristics allow for exact placement and less scrap.

Automotive panel bonding adhesive: applications

Through innovative technologies, material-to-material bonding expertise, and flexibility to form, we create bonds that keep your assembly line moving.

Watershield bonding: direct applied and pre-applied

The watershield is the thin flexible film layer that is bonded directly to the door frame. Watershields protect the electrical components of the door from any damage caused by external water sources. Our direct application adhesives are ideal for use in the assembly line, and our pre-applied adhesives are delivered on a liner, making them ideal for repositionable watershield processes.

Weatherstrip bonding

Automotive weatherstripping is used to protect vehicle interiors from the environment. Weatherstripping needs to be flexible in many aspects, such as the ability to accommodate the vibrations of the vehicle or withstand the extremes of both hot and cold temperatures. The weatherstrip needs an adhesive that is as flexible as the material it’s bonding. 

Automotive body panel adhesive: technologies

We have products in multiple chemistries suitable for bonding weatherstrips and watershields.

Our key technologies include: 

Hot melt polybutene – This adhesive is permanently plastic and tacky and will not dry or crack. It offers heat and humidity resistance, excellent adhesion to plastic and metal and does not require a primer for steel or aluminium substrates.
