Filed: 1988-11-07
Abstract: This invention relates to adhesives, and more 
particularly, epoxy adhesives.  
     The automotive industry has used sheet molding 
compound (SMC) for manufacture of parts for automobile 
bodies. Sheet molding compound typically comprises 
specialty thermosetting polyester resins, reinforcing 
fibers, thickeners to increase the viscosity of the resin 
and to facilitate handling, catalysts to cure the resins, 
filler to lower cost, improve the surface, or add specific 
properties, mold release agent, and pigment.  
     Thermoplastic copolymers have been incorporated in 
sheet molding compound in an effort to improve the 
appearance of painted SMC automobile components. The use 
of thermoplastic copolymers in SMC formulations has 
resulted in severe bonding problems for conventional 
repair adhesives. At present, there are no after market 
adhesives suitable for repairing parts made of SMC.  
     This invention provides a composition comprising 
an epoxy resin, an adduct of a tetra-substituted titanate 
and a di-substituted hydrogen phospite, a neutral ester of 
a phosphorous acid, and a curing agent for the epoxy 
resin.

Title: Recurable and cured cellular materials
IPC: C08J9/36
Filed: 1989-09-05
Abstract: Cured polyimide foam is exposed to an atmosphere of 
steam at elevated temperature and pressure for a period of 
time sufficient to convert the foam into a non-flexible, 
non-resilient recurable cellular material having many 
uses. Preferably the process is conducted such that the 
cellular material is recurable to a flexible resilient 
foam having tensile strength properties similar to the 
tensile strength properties of the original cured polyimide 
foam subjected to the process. Before recuring, the 
non-flexible, non-resilient recurable cellular material 
may be shaped or contoured, and then recured. For example, 
by impressing shaped articles into the recurable 
material followed by recuring, shipping/storage containers 
for the articles are readily produced.
