Low Density Epoxy Syntactic Structural Adhesives for Automotive Applications

摘要

SUMMARY OF THE INVENTION The present invention provides a syntactic structural adhesive comprising an epoxy resin, a low density particulate filler and a hardener, which, when cured, exhibits at least the following balanced properties: (i) a density of less than 1 g/cm 3 ; (ii) a compressive modulus greater than 500 MPa; and (iii) a lap shear strength greater than 750 psi. Syntactic structural adhesives are particularly useful for bonding and/or sealing metal, plastic and composite parts in a variety of applications, such as the automotive sector.
