Adhesives and sealants designed for process efficiencies
Our smart adhesives include a wide range of technologies that cater to specific application needs, offering an easy-to-use process while still being cost-effective. Using smart technologies can reduce cycle time from two to six process steps while also reducing the quantity of adhesive per part. Bostik's leading technologies are available in all regions and have limited health and safety impact.
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.
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.
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.
- Solvent based adhesive
- PUR adhesive
- Rubber adhesive
- Water based adhesive
