TAD-N-PU-2C
联系方式 
TAD-N-PU-2C is a thermally conductive and thixotropic PU adhesive made from highly filled A and B components. The adhesive begins to cure immediately after the two components are thoroughly mixed. TAD-N-PU-2C is characterized by high wetting properties and excellent bond strength on most surfaces. The adhesive system cures completely at room temperature, and curing is accelerated at higher temperatures.
Due to its thixotropic properties, TAD-N-PU-2C can also be used as a dispensable two-component system: Form-in-Place Gap Filler, which creates a precisely placeable gap filler system that cures directly in place, allowing gaps with very tight tolerances to be filled, especially in non-planar structures.
