Polyurethane Thermal Conductive Structural Adhesive
Product Detail
The Polyurethane Thermal Conductive Structural is a dual-component polyurethane thermal conductive structural adhesive with a thermal conductivity available in 1.2 W/m-K and 2.0 W/m-K. It is suitable for bonding between battery cells and cooling plates; and can be utilized for automated adhesive assembly. This material is mixed thoroughly by A and B components through a helical mixing tube. It can cure at room temperature as well at high temperatures. The adhesive surface stress is extremely low (virtually absent), ensuring excellent adhesion to the material interface and resulting in low thermal resistance. Once cured, it securely bonds the battery cells to the cooling plate. Its exceptional structural performance and weather resistance make it particularly suitable for adhesive applications in new energy vehicles. Moreover, the thermal conductive structural adhesive adopts a polyurethane formulation system. It is non-toxic, odorless, non-corrosive, and complies with RoHS directives and relevant environmental requirements.
