Abstract
A novel adhesive has been developed that is particularly adapted for use in bonding automotive components made of sheet molding compound. It is comprised of suitable amounts of cross-linkable epoxy novolac resin; an epoxy flexibilizer; natural and colloidal silica; and an imidazole curing agent substituted in the one position with a short chain hydroxyalkyl group. The adhesive cures to a high bond strength in three minutes at 150.degree. C. It is resistant to degradation due to temperatures up to 200.degree. C., salt spray, humidity and water soak.
